Dependencies
OpenGL 1.2 or GL_EXT_texture3D is required.
Support for ARB_fragment_program is assumed, but not required.
Support for ARB_fragment_program_shadow is assumed, but not required.
Support for EXT_framebuffer_object is assumed, but not required.
Written based on the wording of the OpenGL 2.0 specification and
ARB_fragment_program_shadow but not dependent on them.
Overview
There are a number of circumstances where an application may wish to
blend two textures out of a larger set of textures. Moreover, in some
cases the selected textures may vary on a per-fragment basis within
a polygon. Several examples include:
1. High dynamic range textures. The application stores several
different "exposures" of an image as different textures. On a
per-fragment basis, the application selects which exposures are
used.
2. A terrain engine where the altitude of a point determines the
texture applied to it. If the transition is from beach sand to
grass to rocks to snow, the application will store each texture
in a different texture map, and dynamically select which two
textures to blend at run-time.
3. Storing short video clips in textures. Each depth slice is a
single frame of video.
Several solutions to this problem have been proposed, but they either
involve using a separate texture unit for each texture map or using 3D
textures without mipmaps. Both of these options have major drawbacks.
This extension provides a third alternative that eliminates the major
drawbacks of both previous methods. A new texture target,
TEXTURE_2D_ARRAY, is added that functions identically to TEXTURE_3D in
all aspects except the sizes of the non-base level images. In
traditional 3D texturing, the size of the N+1 LOD is half the size
of the N LOD in all three dimensions. For the TEXTURE_2D_ARRAY target,
the height and width of the N+1 LOD is halved, but the depth is the
same for all levels of detail. The texture then becomes an array of
2D textures. The per-fragment texel is selected by the R texture
coordinate.

Additions to Chapter 2 of the OpenGL 2.0 Specification (OpenGL Operation)
None
Additions to Chapter 3 of the OpenGL 2.0 Specification (Rasterization)
-- Section 3.8.1 "Texture Image Specification"
Change the first paragraph (page 150) to say (spec changes identical to
EXT_texture_array):
"The command
void TexImage3D(enum target, int level, int internalformat,
sizei width, sizei height, sizei depth, int border,
enum format, enum type, void *data);
is used to specify a three-dimensional texture image. target must be one
one of TEXTURE_3D for a three-dimensional texture or
TEXTURE_2D_ARRAY_EXT for an two-dimensional array texture.
Additionally, target may be either PROXY_TEXTURE_3D for a
three-dimensional proxy texture, or PROXY_TEXTURE_2D_ARRAY_EXT for a
two-dimensional proxy array texture."
Change the fourth paragraph on page 151 to say (spec changes identical
to EXT_texture_array):
"Textures with a base internal format of DEPTH_COMPONENT are supported
by texture image specification commands only if target is TEXTURE_1D,
TEXTURE_2D, TEXTURE_1D_ARRAY_EXT, TEXTURE_2D_ARRAY_EXT,
PROXY_TEXTURE_1D, PROXY_TEXTURE_2D, PROXY_TEXTURE_1D_ARRAY_EXT, or
PROXY_TEXTURE_2D_ARRAY_EXT. Using this format in conjunction with any
other target will result in an INVALID_OPERATION error."
Change the fourth paragraph on page 156 to say (spec changes identical
to EXT_texture_array):
"The command
void TexImage2D(enum target, int level,
int internalformat, sizei width, sizei height,
int border, enum format, enum type, void *data);
is used to specify a two-dimensional texture image. target must be one
of TEXTURE_2D for a two-dimensional texture, TEXTURE_1D_ARRAY_EXT for a
one-dimensional array texture, or one of TEXTURE_CUBE_MAP_POSITIVE_X,
TEXTURE_CUBE_MAP_NEGATIVE_X, TEXTURE_CUBE_MAP_POSITIVE_Y,
TEXTURE_CUBE_MAP_NEGATIVE_Y, TEXTURE_CUBE_MAP_POSITIVE_Z, or
TEXTURE_CUBE_MAP_NEGATIVE_Z for a cube map texture. Additionally,
target may be either PROXY_TEXTURE_2D for a two-dimensional proxy
texture, PROXY_TEXTURE_1D_ARRAY_EXT for a one-dimensional proxy array
texture, or PROXY TEXTURE_CUBE_MAP for a cube map proxy texture in the
special case discussed in section 3.8.11. The other parameters match
the corresponding parameters of TexImage3D.
For the purposes of decoding the texture image, TexImage2D is
equivalent to calling TexImage3D with corresponding arguments and depth
of 1, except that
* The border depth, d_b, is zero, and the depth of the image is
always 1 regardless of the value of border.
* The border height, h_b, is zero if <target> is
TEXTURE_1D_ARRAY_EXT, and <border> otherwise.
* Convolution will be performed on the image (possibly changing its
width and height) if SEPARABLE 2D or CONVOLUTION 2D is enabled.
* UNPACK SKIP IMAGES is ignored."
-- Section 3.8.2 "Alternate Texture Image Specification Commands"
Change the second paragraph (page 159) (spec changes identical
to EXT_texture_array):
"The command
void CopyTexImage2D(enum target, int level,
enum internalformat, int x, int y, sizei width,
sizei height, int border);
defines a two-dimensional texture image in exactly the manner of
TexImage2D, except that the image data are taken from the framebuffer
rather than from client memory. Currently, target must be one of
TEXTURE_2D, TEXTURE_1D_ARRAY_EXT, TEXTURE_CUBE_MAP_POSITIVE_X,
TEXTURE_CUBE_MAP_NEGATIVE_X, TEXTURE_CUBE MAP_POSITIVE_Y,
TEXTURE_CUBE_MAP_NEGATIVE_Y, TEXTURE_CUBE_MAP_POSITIVE_Z, or
TEXTURE_CUBE_MAP_NEGATIVE_Z.
Change the last paragraph on page 160 to say (spec changes identical
to EXT_texture_array):
"Currently the target arguments of TexSubImage1D and CopyTexSubImage1D
must be TEXTURE_1D, the target arguments of TexSubImage2D and
CopyTexSubImage2D must be one of TEXTURE_2D, TEXTURE_1D_ARRAY_EXT,
TEXTURE_CUBE_MAP_POSITIVE_X, TEXTURE_CUBE_MAP_NEGATIVE_X,
TEXTURE_CUBE_MAP_POSITIVE_Y, TEXTURE_CUBE_MAP_NEGATIVE_Y,
TEXTURE_CUBE_MAP_POSITIVE_Z, or TEXTURE_CUBE_MAP_NEGATIVE_Z, and the
target arguments of TexSubImage3D and CopyTexSubImage3D must be
TEXTURE_3D or TEXTURE_2D_ARRAY_EXT. ..."
-- Section 3.8.4 "Texture Parameters"
Change the first paragraph (page 166) to say:
"Various parameters control how the texel array is treated when
specified or changed, and when applied to a fragment. Each parameter is
set by calling
void TexParameter{if}(enum target, enum pname, T param);
void TexParameter{if}v(enum target, enum pname, T params);
target is the target, either TEXTURE_1D, TEXTURE_2D, TEXTURE_3D,
TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or TEXTURE_2D_ARRAY_EXT."
-- Section 3.8.8 "Texture Minification" in the section "Scale Factor and Level of Detail"
Change the first paragraph (page 172) to say:
"Let s(x,y) be the function that associates an s texture coordinate
with each set of window coordinates (x,y) that lie within a primitive;
define t(x,y) and r(x,y) analogously. Let u(x,y) = w_t * s(x,y),
v(x,y) = h_t * t(x,y), and w(x,y) = d_t * r(x,y), where w_t, h_t,
and d_t are as defined by equations 3.15, 3.16, and 3.17 with
w_s, h_s, and d_s equal to the width, height, and depth of the
image array whose level is level_base. For a one-dimensional
texture or a one-dimensional array texture, define v(x,y) = 0 and
w(x,y) = 0; for a two-dimensional texture or a two-dimensional array
texture, define w(x,y) = 0..."
-- Section 3.8.8 "Texture Minification" in the section "Mipmapping"
Change the third paragraph (page 174) to say:
"For a two-dimensional texture, two-dimensional array texture, or
cube map texture,"
Change the fourth paragraph (page 174) to say:
"And for a one-dimensional texture or a one-dimensional array texture,"
After the first paragraph (page 175) add:
"For one-dimensional array textures, h_b and d_b are treated as 1,
regardless of the actual values, when performing mipmap calculations.
For two-dimensional array textures, d_b is always treated as one,
regardless of the actual value, when performing mipmap calculations."
-- Section 3.8.8 "Automatic Mipmap Generation" in the section "Mipmapping"
Change the third paragraph (page 176) to say (spec changes identical
to EXT_texture_array):
"The contents of the derived arrays are computed by repeated, filtered
reduction of the level_base array. For one- and two-dimensional array
textures, each layer is filtered independently. ..."
-- Section 3.8.8 "Manual Mipmap Generation" in the section "Mipmapping"
Change first paragraph to say (spec changes identical to
EXT_texture_array):
"Mipmaps can be generated manually with the command
void GenerateMipmapEXT(enum target);
where <target> is one of TEXTURE_1D, TEXTURE_2D, TEXTURE_CUBE_MAP,
TEXTURE_3D, TEXTURE_1D_ARRAY, or TEXTURE_2D_ARRAY. Mipmap generation
affects the texture image attached to <target>. ..."
-- Section 3.8.10 "Texture Completeness"
Change the second paragaph (page 177) to say (spec changes identical
to EXT_texture_array):
"For one-, two-, or three-dimensional textures and one- or
two-dimensional array textures, a texture is complete if the following
conditions all hold true:"
-- Section 3.8.11 "Texture State and Proxy State"
Change the second and third paragraphs (page 179) to say (spec changes
identical to EXT_texture_array):
"In addition to image arrays for one-, two-, and three-dimensional
textures, one- and two-dimensional array textures, and the six image
arrays for the cube map texture, partially instantiated image arrays
are maintained for one-, two-, and three-dimensional textures and one-
and two-dimensional array textures. Additionally, a single proxy image
array is maintained for the cube map texture. Each proxy image array
includes width, height, depth, border width, and internal format state
values, as well as state for the red, green, blue, alpha, luminance,
and intensity component resolutions. Proxy image arrays do not include
image data, nor do they include texture properties. When TexImage3D is
executed with target specified as PROXY_TEXTURE_3D, the
three-dimensional proxy state values of the specified level-of-detail
are recomputed and updated. If the image array would not be supported
by TexImage3D called with target set to TEXTURE 3D, no error is
generated, but the proxy width, height, depth, border width, and
component resolutions are set to zero. If the image array would be
supported by such a call to TexImage3D, the proxy state values are set
exactly as though the actual image array were being specified. No pixel
data are transferred or processed in either case.
Proxy arrays for one- and two-dimensional textures and one- and
two-dimensional array textures are operated on in the same way when
TexImage1D is executed with target specified as PROXY_TEXTURE_1D,
TexImage2D is executed with target specified as PROXY_TEXTURE_2D or
PROXY_TEXTURE_1D_ARRAY_EXT, or TexImage3D is executed with target
specified as PROXY_TETXURE_2D_ARRAY_EXT."
-- Section 3.8.12 "Texture Objects"
Change section (page 180) to say (spec changes identical to
EXT_texture_array):
"In addition to the default textures TEXTURE_1D, TEXTURE_2D,
TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and TEXTURE_2D_EXT,
named one-, two-, and three-dimensional, cube map, and one- and
two-dimensional array texture objects can be created and operated upon.
The name space for texture objects is the unsigned integers, with zero
reserved by the GL.
A texture object is created by binding an unused name to TEXTURE_1D,
TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or
TEXTURE_2D_ARRAY_EXT. The binding is effected by calling
void BindTexture(enum target, uint texture);
with <target> set to the desired texture target and <texture> set to
the unused name. The resulting texture object is a new state vector,
comprising all the state values listed in section 3.8.11, set to the
same initial values. If the new texture object is bound to TEXTURE_1D,
TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or
TEXTURE_2D_ARRAY_EXT, it is and remains a one-, two-,
three-dimensional, cube map, one- or two-dimensional array texture
respectively until it is deleted.
BindTexture may also be used to bind an existing texture object to
either TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP,
TEXTURE_1D_ARRAY_EXT, or TEXTURE_2D_ARRAY_EXT. The error
INVALID_OPERATION is generated if an attempt is made to bind a texture
object of different dimensionality than the specified target. If the
bind is successful no change is made to the state of the bound texture
object, and any previous binding to target is broken.
While a texture object is bound, GL operations on the target to which
it is bound affect the bound object, and queries of the target to which
it is bound return state from the bound object. If texture mapping of
the dimensionality of the target to which a texture object is bound is
enabled, the state of the bound texture object directs the texturing
operation.
In the initial state, TEXTURE_1D, TEXTURE_2D, TEXTURE_3D,
TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and TEXTURE_2D_ARRAY_EXT have
one-, two-, three-dimensional, cube map, and one- and two-dimensional
array texture state vectors respectively associated with them. In order
that access to these initial textures not be lost, they are treated as
texture objects all of whose names are 0. The initial one-, two-,
three-dimensional, cube map, one- and two-dimensional array textures
are therefore operated upon, queried, and applied as TEXTURE_1D,
TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, and
TEXTURE_2D_ARRAY_EXT respectively while 0 is bound to the corresponding
targets.
Change second paragraph on page 181 to say (spec changes identical to
EXT_texture_array):
"... If a texture that is currently bound to one of the targets
TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP,
TEXTURE_1D_ARRAY_EXT, or TEXTURE_2D_ARRAY_EXT is deleted, it is as
though BindTexture had been executed with the same target and texture
zero. ..."
Change second paragraph on page 182 to say (spec changes identical to
EXT_texture_array):
"The texture object name space, including the initial one-, two-, and
three dimensional, cube map, and one- and two-dimensional array texture
objects, is shared among all texture units. ..."
-- Section 3.8.14 "Depth Texture Comparison Modes" in "Texture Comparison Modes"
Change second through fourth paragraphs (page 188) to say:
"Let D_t be the depth texture value, in the range [0, 1]. For
texture lookups from one- and two-dimesional, rectangle, and
one-dimensional array targets, let R be the interpolated <r>
texture coordinate, clamped to the range [0, 1]. For texture lookups
from two-dimesional array texture targets, let R be the interpolated
<q> texture coordinate, clamped to the range [0, 1]. Then the
effective texture value L_t, I_t, or A_t is computed as follows:
If the value of TEXTURE_COMPARE_MODE is NONE, then
r = Dt
If the value of TEXTURE_COMPARE_MODE is
COMPARE_REF_DEPTH_TO_TEXTURE_EXT), then r depends on the texture
comparison function as shown in table 3.27."
-- Section 3.8.15 "Texture Application"
Change the first paragraph (page 189) to say:
"Texturing is enabled or disabled using the generic Enable and Disable
commands, respectively, with the symbolic constants TEXTURE_1D,
TEXTURE_2D, TEXTURE_3D, TEXTURE_CUBE_MAP, TEXTURE_1D_ARRAY_EXT, or
TEXTURE_2D_ARRAY_EXT to enable one-, two-, three-dimensional, cube
map, one-dimensional array, or two-dimensional array texture,
respectively. If both two- and one-dimensional textures are enabled,
the two-dimensional texture is used. If the three-dimensional and
either of the two- or one-dimensional textures is enabled, the
three-dimensional texture is used. If the cube map texture and any of
the three-, two-, or one-dimensional textures is enabled, then cube map
texturing is used. If one-dimensional array texture is enabled and any
of cube map, three-, two-, or one-dimensional textures is enabled,
one-dimensional array texturing is used. If two-dimensional array
texture is enabled and any of cube map, three-, two-, one-dimensional
textures or one-dimensional array texture is enabled, two-dimensional
array texturing is used..."

-- Section 3.11.6 "Fragment Program Texture Instruction Set"
(replace 1st and 2nd paragraphs with the following paragraphs)
"The first three texture instructions described below specify the
mapping of 4-tuple input vectors to 4-tuple output vectors.
The sampling of the texture works as described in section 3.8,
except that texture environments and texture functions are not
applicable, and the texture enables hierarchy is replaced by explicit
references to the desired texture target (i.e., 1D, 2D, 3D, cube map,
rectangle, ARRAY1D, ARRAY2D). These texture instructions specify
how the 4-tuple is mapped into the coordinates used for sampling. The
following function is used to describe the texture sampling in the
descriptions below:
vec4 TextureSample(vec4 coord, float lodBias, int texImageUnit,
enum texTarget);

Additions to Chapter 4 of the OpenGL 2.0 Specification (Per-Fragment Operations)
-- Section 4.4.2.3 "Attaching Texture Images to a Framebuffer"
Add to the end of the section (spec changes identical to
EXT_texture_array):
"The command
void FramebufferTextureLayerEXT(enum target, enum attachment,
uint texture, int level, int layer);
operates identically to FramebufferTexture3DEXT, except that it
attaches a single layer of a three-dimensional texture or a one- or
two-dimensional array texture. <layer> is an integer indicating the
layer number, and is treated identically to the <zoffset> parameter in
FramebufferTexture3DEXT. The error INVALID_VALUE is generated if
<layer> is negative. The error INVALID_OPERATION is generated if
<texture> is non-zero and is not the name of a three dimensional
texture or one- or two-dimensional array texture. Unlike
FramebufferTexture3D, no <textarget> parameter is accepted.
If <texture> is non-zero and the command does not result in an error,
the framebuffer attachment state corresponding to <attachment> is
updated as in the other FramebufferTexture commands, except that
FRAMEBUFFER_ATTACHMENT_TEXTURE_LAYER_EXT is set to <layer>."
-- Section 4.4.4.1 "Framebuffer Attachment Completeness"
Add to the end of the list of completeness rules (spec changes
identical to EXT_texture_array):
"* If FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE_EXT is TEXTURE and
FRAMEBUFFER_ATTACHMENT_OBJECT_NAME_EXT names a one- or
two-dimensional array texture, then
FRAMEBUFFER_ATTACHMENT_TEXTURE_LAYER_EXT must be smaller than the
number of layers in the texture."
Additions to Chapter 5 of the OpenGL 2.0 Specification (Special Functions)
-- Section 5.4 "Display Lists"
Change the first paragraphi on page 242 to say (spec changes
identical to EXT_texture_array):
"TexImage3D, TexImage2D, TexImage1D, Histogram, and ColorTable are
executed immediately when called with the corresponding proxy arguments
PROXY_TEXTURE_3D or PROXY_TEXTURE_2D_ARRAY_EXT; PROXY_TEXTURE_2D,

PROXY_POST_COLOR_MATRIX_COLOR_TABLE."
Additions to Chapter 6 of the OpenGL 2.0 Specification (State and State Requests)
-- Section 6.1.3 "Enumerated Queries"
Add after the line beginning "If the value of
FRAMEBUFFER_ATTACHMENT_OBJECT_TYPE_EXT is TEXTURE" (spec changes
identical to EXT_texture_array):
"If <pname> is FRAMEBUFFER_ATTACHMENT_TEXTURE_LAYER_EXT and the
texture object named FRAMEBUFFER_ATTACHMENT_OBJECT_NAME_EXT is a
three-dimensional texture or a one- or two-dimensional array texture,
then <params> will contain the number of texture layer attached to the
attachment point. Otherwise, <params> will contain the value zero."
-- Section 6.1.4 "Texture Queries"
Change the first three paragraphs (page 248) to say (spec changes
identical to EXT_texture_array):
"The command
void GetTexImage(enum tex, int lod, enum format,
enum type, void *img);
is used to obtain texture images. It is somewhat different from the
other get commands; tex is a symbolic value indicating which texture
(or texture face in the case of a cube map texture target name) is to
be obtained. TEXTURE_1D, TEXTURE_2D, TEXTURE_3D, TEXTURE_1D_ARRAY_EXT,
and TEXTURE_2D_ARRAY_EXT indicate a one-, two-, or three-dimensional
texture, or one- or two-dimensional array texture, respectively.

Dependencies on ARB_fragment_program
If ARB_fragment_program is not supported, the changes to section 3.11
should be ignored.
Dependencies on EXT_framebuffer_object
If EXT_framebuffer_object is not supported, the changes to section
3.8.8 ("Manual Mipmap Generation"), 4.4.2.3, and 6.1.3 should be ignored.
Dependencies on EXT_texture_compression_s3tc and NV_texture_compression_vtc
(Identical dependency as EXT_texture_array.)
S3TC texture compression is supported for two-dimensional array textures.
When <target> is TEXTURE_2D_ARRAY_EXT, each layer is stored independently
as a compressed two-dimensional textures. When specifying or querying
compressed images using one of the S3TC formats, the images are provided
and/or returned as a series of two-dimensional textures stored
consecutively in memory, with the layer closest to zero specified first.
For array textures, images are not arranged in 4x4x4 or 4x4x2 blocks as in
the three-dimensional compression format provided in the
EXT_texture_compression_vtc extension. Pixel store parameters, including
those specific to three-dimensional images, are ignored when compressed
image data are provided or returned, as in the
EXT_texture_compression_s3tc extension.
S3TC compression is not supported for one-dimensional texture targets in
EXT_texture_compression_s3tc, and is not supported for one-dimensional
array textures in this extension. If compressed one-dimensional arrays
are needed, use a two-dimensional texture with a height of one.
This extension allows the use of the four S3TC internal format types in
TexImage3D, CompressedTexImage3D, and CompressedTexSubImage3D calls.

Issues
(1) Is "texture stack" a good name for this functionality?
NO. The name is changed to "array texture" to match the
nomenclature used by GL_EXT_texture_array.
(2) Should the R texture coordinate be treated as normalized or
un-normalized? If it were un-normalized, floor(R) could be thought
of as a direct index into the array texture. This may be more
convenient for applications.
RESOLVED. All texture coordinates are normalized. The issue of
un-normalized texture coordinates has been discussed in the ARB
before and should be left for a layered extension.
RE-RESOLVED. The R coordinate is un-normalized. Accessing an array
using [0, layers-1] coordinates is much more natural.
(3) How does LOD selection work for stacked textures?
RESOLVED. For 2D array textures the R coordinate is ignored, and
the LOD selection equations for 2D textures are used. For 1D
array textures the T coordinate is ignored, and the LOD selection
equations for 1D textures are used. The expected usage is in a
fragment program with an explicit LOD selection.
(4) What is the maximum size of a 2D array texture? Is it the same
as for a 3D texture, or should a new query be added? How about for 1D
array textures?
RESOLVED. A new query is added.
(5) How are array textures exposed in GLSL?
RESOLVED. Use GL_EXT_texture_array.
(6) Should a 1D array texture also be exposed?
RESOLVED. For orthogonality, yes.
(7) How are stacked textures attached to framebuffer objects?
RESOLVED. Layers of both one- and two-dimensional array textures
are attached using FreambufferTextureLayerEXT. Once attached, the
array texture layer behaves exactly as either a one- or
two-dimensional texture.
(8) How is this extension related to GL_EXT_texture_array?
This extension adapats GL_MESAX_texture_stack to the notation,
indexing, and FBO access of GL_EXT_texture_array. This extension
replaces the GLSL support of GL_EXT_texture_array with
GL_ARB_fragment_program support.
Assembly program support is also provided by GL_NV_gpu_program4.
GL_NV_gpu_program4 also adds support for other features that are
specific to Nvidia hardware, while this extension adds only support
for array textures.
Much of text of this extension that has changed since
GL_MESAX_texture_stack comes directly from either
GL_EXT_texture_array or GL_NV_gpu_program4.

Quick Start
----- -----
Unzip the MesaLib, MesaGLUT, and MesaDemos ZIP files into the same
directory. The libs and demos build separately, so if you do not care
about the demos or GLUT, you only need to unzip MesaLib. If you unzip
more than one ZIP file, they all need to be unzipped into the same
directory. Don't worry, you will not overwrite anything.
The Windows build system uses Microsoft Visual Studio. Project files
for a specific version of Visual Studio are in their own directory in
the top-level "windows" directory. For example, Visual Studio 6 files
are in windows/VC6. If a directory does not exist for your version of
Visual Studio, you can try importing the project files from an earlier
version of Visual Studio. At this time, project files exist for
Version 6 and Version 7. The code has been built with a beta version
of Version 8 and it runs on 64-bit Windows. If you want to try this,
start by importing the VC7 files and create the 64-bit targets in the
configuration manager.
It is likely that the new and free Visual Studio Express can be used
to build Mesa, but it hasn't been tried yet. Start with the VC7
project files.
The project files to build the core Mesa library, Windows Mesa
drivers, OSMesa, and GLU are in the mesa directory. The project files
to build GLUT and some demo programs are in the progs directory.
Makefiles are no longer shipped or supported, but can be generated
from the projects using Visual Studio.
Windows Drivers
------- -------
At this time, only the GDI driver is known to work. Most of the demos
in progs/demos should work with this driver.
Source code also exists in the tree for other drivers in
src/mesa/drivers/windows, but the status of this code is unknown.
The GDI driver operates basically by writing pixel spans into a DIB
section and then blitting the DIB to the window. The driver was
recently cleaned up and rewitten and so may have bugs or may be
missing some functionality. The older versions of the CVS source may
be useful in figuring out any problems, or report them to me.
To build Mesa with the GDI driver, build the mesa, gdi, and glu
projects in the Visual Studio workspace found at
windows/VC6/mesa/mesa.dsw
or
windows/VC7/mesa/mesa.sln
The osmesa DLL can also be built with the osmesa project.
The build system creates a lib top-level directory and copies
resulting LIB and DLL files to this lib directory. The files are:
OPENGL32.LIB, GLU32.LIB, OSMESA32.LIB
OPENGL32.DLL, GLU32.DLL, OSMESA32.DLL
If the MesaDemos ZIP file was extracted, the DLL files are also copied
to the demos directory. This facilitates running the demos as described
below.
GLUT and Demos
---- --- -----
A Visual Studio workspace can be found at
windows/VC6/progs/progs.dsw
or
windows/VC7/progs/progs.sln
It can be used to build GLUT and a few demos. The GLUT lib and DLL
are copied to the top-level lib directory, along with the Mesa libs.
The demo build system expects to find the LIB files in the top level
lib directory, so you must build the Mesa libs first. The demo
executables are placed in the demos directory, because some of them
rely on data files found there. Also, the Mesa lib DLL's were copied
there by the Mesa lib build process. Therefore, you should be able to
simply run the demo executables from the demo directory.
If you want to run the demos from the Visual Studio, you may have to
change the startup directory and explicitly state where the executables are.
You may also build all the demo programs by using a makefile. Go to
the progs/demos directory and make sure you have executed VCVARS32.BAT
or whatever setup script is appropriate for your compiler. Then,
nmake -f Makefile.win
should build all the demos.
Build System Notes
----- ------ -----
VC6
---
Visual Studio 6 does not recognize files with the .cc extension as C++
language files, without a lot of unnatural tweaking. So, the VC6
build process uses custom build steps to compile these files in the
GLU library.
Two additional configurations are provided, Debug x86 and Release x86
that activate the shader code compilation by defining SLANG_86. It is
unknown if and how this works.
VC7
---
The above-mentioned .cc problem does not exist in this version.
General
-------
After building, you can copy the above DLL files to a place in your
PATH such as $SystemRoot/SYSTEM32. If you don't like putting things
in a system directory, place them in the same directory as the
executable(s). Be careful about accidentially overwriting files of
the same name in the SYSTEM32 directory.
The DLL files are built so that the external entry points use the
stdcall calling convention.
Static LIB files are not built. The LIB files that are built with are
the linker import files associated with the DLL files.
The si-glu sources are used to build the GLU libs. This was done
mainly to get the better tessellator code.
To build "mangled" Mesa, add the preprocessor define USE_MGL_NAMESPACE
to the project settings. You will also need to edit src/mesa.def to
change all the gl* symbols to mgl*. Because this is easy to do with a
global replace operation in a text editor, no additional mangled
version of mesa.def is maintained or shipped.
If you have a Windows-related build problem or question, it is
probably better to direct it to me (kschultz@users.sourceforge.net),
rather than directly to the other Mesa developers. I will help you as
much as I can. I also monitor the Mesa mailing lists and will answer
questions in this area there as well.

for a specific version of Visual Studio are in their own directory in
the top-level "windows" directory. For example, Visual Studio 8 files
are in windows/VC8.
Support has been dropped for versions of Visual Studio prior to 8. The
main reason is because Microsoft now provides a free compiler and
developer environment. Visual Studio Express can be found at
http://msdn.microsoft.com/vstudio/express/visualc/default.aspx
You'll also need the Platform SDK. Instructions for obtaining and
using the SDK with Visual Studio Express can be found at
http://msdn.microsoft.com/vstudio/express/visualc/usingpsdk/
If you are stuck using VC6 or VC7, you may start with these project
files, but you may need to modify them to reflect changes in the
Mesa source code tree. If you sucessfully update the project files,
please submit them to the author of this document so that they may
be included in the next distribution.
The project files to build the core Mesa library, Windows Mesa
drivers, OSMesa, and GLU are in the mesa directory. The project files
to build GLUT and some demo programs are in the progs directory.

<H1>1. Introduction</H1>
<p>
The fbdev/DRI sub-project within Mesa brings hardware accelerated OpenGL
rendering to the Linux fbdev environment.
The X Window System / XFree86 is not needed.
The fbdev/DRI environment supports hardware-accelerated 3D rendering without
the X window system. This is typically used for embedded applications.
</p>
<p>
Basically, the <a href="http://dri.sf.net/">DRI</a> drivers for hardware
accelerated OpenGL for XFree86 have been ported to fbdev so that X is
not needed.
This means fbdev/DRI works in full-screen mode only.
Contributors to this project include Jon Smirl, Keith Whitwell and Dave Airlie.
</p>
<p>
DRI driver writers may find this simplified environment easier to work in,
compared to the full XFree86/DRI environment.
Applications in the fbdev/DRI environment use
the <a href="MiniGXL.html"> MiniGLX</a> interface to choose pixel
formats, create rendering contexts, etc. It's a subset of the GLX and
Xlib interfaces allowing some degree of application portability between
the X and X-less environments.
</p>
<p>
Much of the work for this project has been done by Jon Smirl and
Keith Whitwell.
</p>
<p>
To use fbdev/DRI, you'll need a Linux 2.4 or 2.6 kernel.
</p>
<h3>Background Info</h3>
<p>
The Mesa-based DRI drivers used to be hosted in the DRI tree (which is
basically a copy of the XFree86 tree).
Since the Mesa-based DRI drivers are moreso "Mesa drivers" than "XFree86
drivers" and the fact that with some work, the drivers could be used
without X, the driver code was moved into the Mesa tree.
</p>
<p>
So now the DRI drivers can be compiled for two different environments:
fbdev and XFree86.
To build the drivers for XFree86, one has to download/build the DRI
source tree.
Eventually, we'd like to be able to build the drivers for XFree86 outside
of the XFree86/DRI trees.
</p>
<h1>2. Compilation</h1>
<h2>2.1 Compiling the DRM modules</h2>
<p>
First, you'll need the DRM (Direct Rendering Manager) kernel module sources.
They're found in a module of the DRI CVS tree.
To obtain the code do the following:
You'll need the DRM and pciaccess libraries. Check with:
</p>
<pre>
cvs -d:pserver:anonymous@anoncvs.freedesktop.org:/cvs/dri login
</pre>
<p>
Press Enter/Return when prompted for a password. Then,
</p>
<pre>
cvs -d:pserver:anonymous@anoncvs.freedesktop.org:/cvs/dri co drm
pkg-config --modversion libdrm
pkg-config --modversion pciaccess
</pre>
<p>
Compile the DRM kernel modules:
You can get them from the git repository with:
</p>
<pre>
cd drm/linux
make
git clone git://anongit.freedesktop.org/git/mesa/drm
git clone git://anongit.freedesktop.org/git/xorg/lib/libpciaccess
</pre>
<p>
Note: you may need to be root in order to make a few symlinks.
See the README files in those projects for build/install instructions.
</p>
<p>
When compilation is done, you should have at least the following
kernel modules:
You'll need fbdev header files. Check with:
</p>
<pre>
gamma.o
i810.o
i830.o
mach64.o
mga.o
r128.o
radeon.o
savage.o
sis.o
tdfx.o
via.o
ls -l /usr/include/linux/fb.h
</pre>
<p>
You'll probably want to copy/move them into your kernel module directory
(for example: <code>/lib/modules/2.4.18-14/kernel/drivers/char/drm/</code>).
</p>
<h2>2.2 Compiling the Mesa drivers</h2>
<p>
Begin by editing the <code>Mesa/configs/default</code> file to set
the <code>DRM_SOURCE_PATH</code> variable.
Set it to the location where the DRM module sources are located.
For example, if your current directory in step 2.1 was <code>/home/fred/</code>
set DRM_SOURCE_PATH to <code>/home/fred/drm</code>
</p>
<p>
Next, assuming you're starting with a fresh Mesa CVS checkout,
do the following:
Compile Mesa with the 'linux-solo' configuration:
</p>
<pre>
make linux-solo
</pre>
<p>
If you previously built the source tree, run <code>make realclean</code>
first to remove the old object files.
When complete you should have the following:
</p>
<p>
When this is finished, check the <code>Mesa/lib/</code> directory
to verify that the following files were made:
</p>
<ul>
<li><code>libGL.so.1.2</code> - the client-side OpenGL library
(and a few symlinks to it).
<li><code>libGLU.so.1.1</code> - the GLU library (and a few symlinks to it).
<li><code>libglut.so.3.7</code> - the GLUT library (and a few symlinks to it).
<li><code>mga_dri.so</code> - DRI driver for Matrox G200/G400 cards.
<li><code>r128_dri.so</code> - DRI driver for ATI Rage 128 cards.
<li><code>r200_dri.so</code> - DRI driver for ATI R200 Radeon cards.
<li><code>radeon_dri.so</code> - DRI driver for original ATI Radeon cards.
<li><code>i810_dri.so</code> - DRI driver for Intel i810/i815 chips.
<li><code>i830_dri.so</code> - DRI driver for Intel i830/i845 chips.
<li><code>mga_dri.so</code> - DRI driver for Matrox G200/G400 cards.
<li><code>sis_dri.so</code> - DRI driver for SIS cards.
<li><code>tdfx_dri.so</code> - DRI driver for 3dfx Voodoo 3/4/5 cards.
<li><code>gamma_dri.so</code> - DRI driver for 3Dlabs gamma cards.
<li><code>fb_dri.so</code> - software-only fbdev driver.
<li><code>miniglx.conf</code> - configuration file for the MiniGLX interface
<li>lib/libGL.so - the GL library which applications link with
<li>lib/*_dri_so - DRI drivers
<li>lib/miniglx.conf - sample MiniGLX config file
<li>progs/miniglx/* - several MiniGLX sample programs
</ul>

<h2>Shared library numbering</h2>
<p>
Mesa 6.5.3 supports the OpenGL 2.0/2.1 API. However, the (unix)
shared library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx).
Bumping the shared library version to 2.x would cause linking problems
with existing OpenGL applications. Since OpenGL 2.x is backward
compatible with OpenGL 1.x the shared library version number doesn't
have to be incremented (which would indicate an incompatible ABI).

In 2002/2003 Tungsten Graphics was contracted to develop a subset Mesa/Radeon
driver for an embedded environment. The result is a reduced-size DRI driver
for the ATI R200 chip, for use with Linux fbdev rather than XFree86.
