Hi, I'm trying to come up with a design using OSG to build what i'm calling an "X-ray" viewer. Basically i have relatively simple geometry, a "shell" or "skin" of a vehicle and then the "interior." I want to view the interior as "penetrated" by the X-rays, which is based on a "thickness" calculation and a "distance" and "aspect" angle, all hopefully done in shaders. I envision the shaders setting the fragment alpha and/or color when rendering the "shell", then after to render the "interior" and combine with the "shell" texture to create the final view, showing through the interior in desired parts. Finally, i desire to get a histogram of the colors of the interior to see how the "shell" performed on the x-rays with the interior.
Do you see this as an appropriate application / use of osgppu? i'm running osg 2.8.1. will ppu work with that. i've got osgppu 0.4 i think. also, i'm thinking i need to create the ppu nodes programmatically instead of reading ppu files, so i need examples of that type. i'm just starting to look through them. Thank you!
