[osg-users] How to render (sub-)graph only into depth buffer?

[Robert Osfield]

HI Hartwig,

What you describe is a multiple pass render to texture, the way one
does this with the OSG is to use an osg::Camera placed as slave Camera
or a Camera placed in the scene graph.  The Camera has a setRederOrder
method this tells the cull traversal what order to draw things in.
Have a look at the osgVolume::MultipassTechnique for an example of
rendering to a depth texture and then using the result in the main
pass.

Robert.
