<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
<a href="http://www.khronos.org/openvg/" target="_parent">
http://www.khronos.org/openvg/</a> .
</p>
<p>
The OpenVG state tracker depends on the Gallium architecture and a working EGL implementation.
</p>
<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>
