[osg-users] Shaders with multiple views, possible?

[Julien Valentin]

Hi Antoine

Reasons are undertandables through osg adaptation to across openGL history/evolution:

In OpenGL2 there were builtins gl_XXX, in OpenGL3 these builtins have been removed. To make this evolution seamless osg brough you the osg_XXX uniforms that should be use if you're planning to deploy on GL3 core profile.

Cheers
