Have you taken a look at osgVolume, or perhaps the depth peeling example? I
don't know whether you want true volume visualization, or just simple
transparency would suffice, so I'm directing you to both.

Hello,

 

We are investigating the design of an app to produce images of geometry
objects where some objects are "inside" others, and we want a custom /
flexible algorithm to control the render color of the "hidden" objects,
using an X-ray analogy, where "shielding" / other data properties of some
geometry  nodes (i.e., the "shell") would be used to control the display of
other nodes (e.g., the "core").

 

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
