Thanks. I guess I don't know yet. just getting started with it.

I don't know whether you want true volume visualization, or just simple transparency would suffice, so I'm directing you to both.

We'd like to hear your opinions on the best methods to approach this using osg. Custom CullVisitor, Custom DrawCallback, GLSL / shader programming, etc.? Would separate geodes be preferable to light sources for the "rays?" Are there existing similar applications? Thanks in advance, Bob Youmans
