<H1>OpenVG State Tracker</H1>
|
|
|
|
<p>
|
|
The current version of the OpenVG state tracker implements OpenVG 1.0.
|
|
</p>
|
|
<p>
|
|
More informations about OpenVG can be found at

|

</p>
|
|
<p>
|
|
The OpenVG state tracker depends on the Gallium architecture and a working EGL implementation.

<h2>Building the library</h2>
|
|
<ol>
|
|
<li>Build Mesa3D with Gallium3D. Any build that builds Gallium3D libraries and EGL will suffice</li>
|
|
<li>cd src/gallium/state_trackers/vega; make</li>
|
|
<li>The last step will build libOpenVG library. You can add the libdir to LD_LIBRARY_PATH or install libOpenVG</li>
|
|
</ol>
|
|
|
|
<h3>Sample build</h3>
|
|
A sample build looks as follows:
|
|
<pre>
|
|
make linux-x86-64-debug
|
|
cd src/gallium/state_trackers/vega
|
|
make
|
|
cd ../../../..
|
|
export LD_LIBRARY_PATH=$PWD/lib64
|
|
export EGL_DRIVER="egl_softpipe"
|
|
</pre>
|
|
|
|
<h2>OpenVG Demos</h2>
|
|
|
|
<p>
|
|
To build the OpenVG demos:
|
|
</p>
|
|
<pre>
|
|
cd progs/openvg
|
|
make
|
|
</pre>
|
|
<p>
|
|
To run a demo:
|
|
</p>
|
|
<pre>
|
|
cd openvg/demos
|
|
./lion
|
|
</pre>
|
|
|
|
|
|
<h2>Notes</h2>
|
|
<ul>
|
|
<li>EGL_DRIVER environmental variable: forces usage of a specific EGL driver. Unless you force egl_softpipe the implementation will look for a DRI hardware accelerate driver and unless you have a Gallium driver that supports it, you'll see crashes</li>
|
|
</ul>
