Integrating With Your project
It's not too hard to use VSXu as part of your project.
If you want to utilize the OpenGL features, all you have to do is run vsxu
within an OpenGL context. This means it integrates well with Qt or other tools
for instance.
If you don't want to use OpenGL - it's still possible, the engine itself doesn't
make any use of OpenGL, but of course there is a limited amount of modules available...
An example
For a good example on how to initialize vsxu it's good to look at the code for vsxu_server:
