LibGGI driver for Mesa-3.0
|
||||
by Uwe Maurer (uwe_maurer@t-online.de)
|
||||
GGIMesa for LibGGI 2.x
|
||||
|
||||
Requirements:
|
||||
-------------
|
||||
LibGGI 2.0 or greater
|
||||
|
||||
Introduction
|
||||
============
|
||||
[from libggi.txt by Steve Cheng and Hartmut Niemann]
|
||||
Installation:
|
||||
-------------
|
||||
To install GGIMesa, follow the instructions in INSTALL.GNU. If you
|
||||
wish to install GGIGLUT as well, first install GGIMesa and then run
|
||||
|
||||
"LibGGI, the dynamic GGI (General Graphics Interface) library is a
|
||||
flexible drawing library.
|
||||
make
|
||||
make install (must be root)
|
||||
|
||||
It provides an opaque interface to the display's acceleration
|
||||
functions. It was originally intended to allow user programs to
|
||||
interface with KGI, the kernel side of the GGI code, but other display
|
||||
types can be easily used by loading the appropriate "display target"
|
||||
(e.g. X, memory).
|
||||
in ggi/ggiglut.
|
||||
|
||||
LibGGI consists of a main library (libggi.so) and a multitude of
|
||||
dynamic drivers. The library then loads the necessary "drivers" for
|
||||
the requested mode, taking hints from the graphics device if
|
||||
necessary. LibGGI can also load extension libraries, e.g. to provide
|
||||
enhanced 2D and 3D functions.
|
||||
Notes:
|
||||
------
|
||||
|
||||
It has been designed after having a look at several existing
|
||||
libraries, and so far we have found porting to be quite simple from
|
||||
and to most of them."
|
||||
* Set the environment variables GGIMESA_DEBUG and/or GGIGLUT_DEBUG
|
||||
to 255 to see lots of debugging output.
|
||||

||||

|
||||
|
||||
More information about the GGI project and LibGGI can be
|
||||
obtained from the GGI website:

|
||||
|
||||
Installation
|
||||
============
|
||||
|
||||
- Install LibGGI
|
||||
|
||||
- Unpack the Mesa archives
|
||||
|
||||
- In the Mesa directory type:
|
||||
|
||||
make linux-ggi
|
||||
su
|
||||
make linux-ggi-install
|
||||
exit
|
||||
|
||||
- Now you can try some demos.
|
||||
If they don't work, you can set the GGIMESA_DEBUG
|
||||
variable to 255 and you will see some information from the
|
||||
LibGGI-driver.
|
||||
|
||||
export GGIMESA_DEBUG=255
|
||||
|
||||
|
||||
GLUT
|
||||
====
|
||||
|
||||
You can change these default values in ggi/ggiglut.c:
|
||||
#define WIDTH 640
|
||||
#define HEIGHT 400
|
||||
#define GRAPHTYPE_RGB GT_16BIT
|
||||
#define GRAPHTYPE_INDEX GT_8BIT
|
||||
|
||||
Options:
|
||||
-bpp x Set graphic mode with x bits per pixel
|
||||
-size x y Screen (or window) is x*y pixels
|
||||
|
||||
Example:
|
||||
demos/gears -size 320 200 -bpp 24
|
||||

* GGIGLUT contains support for all of the GLUT 3.6 API except for the
|
||||
high-level primitive drawing functions, but many of the functions (in
|
||||
particular the menu drawing functions) are just stubs.
