Question Generating UV map programmatically with 3d and textures generated at runtime.

Hello,

I have a project to generate 3d objects from external data received. In these data I receive also images about the original real objects and I convert in textures.

My big issue is apply the texture on the relative 3d objects because the UV mapping must be generated realtime and to be adapted for any specific 3d with texture. I tried various codes and tutorials. The results are the texture wrong applied, stretched or replicated. There is some code with the generic algorithm for my case? Someone can help me? Thanks.

UPDATE: I forgot a detail: I need to apply the texture on the top side only of the 3D.

 

Sounds like you want to use perspective projection mapping.
