hi…
I post this here not because I’m an OpenGL expert, but because it is a question that doesn’t appear to be answered elsewhere so I assume it is advanced.
I would like to create a user-defined cross-sectional view of a 3D mesh. Clipping is easy, but I’m not sure of the best way to handle textures. I could keep it simple and use basic colors, but it would be good to change the textures in 3D if possible.
It seems this particular problem might be easier if i do a volumetric render, but the device in question (iPad 2) lacks compute shaders so i’m anticipating that it would be slower and require a non-standard workflow. i would be happy to be proved wrong, however.
thanks!
