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
