Re: [osg-users] Rendering to a texture only

Hi, wrt question 1: you could look at Mesa (www.mesa3d.org) and use their OSMesa (off-screen) library. It is a software-only (obviously slow compared to hardware) OpenGL 2.1 implementation and works well with OSG. This will allow you to render to main memory in the PC. jp Williams Steven-ASW0
