[osg-users] Render to texture ONLY?

[Sebastian Messerschmidt]

Hi Chris,

Take a look at the osgprerender example. It shows you how to render to  
a framebuffer object.
The bound texture can be used to be displayed later on.

Cheers
Sebastian

Ideally the viewer would be able to render to a texture, rather than to a screen, or window on a screen. I basically need a headless 3D process running, where the OSG output is going to a texture.
