- OK. Everyone (well, almost everyone) is familiar with the idea of texture
- mapping in the context of computer graphics. I.E. You have a 3D object that
- you wish to render, and you wrap a texture or image onto that object to create
- a more realistic image. With ray-tracing, the whole process is not entirely
- difficult to program if you know what you're doing.
-
- Anyway, the idea I had was: Given that you have a ray traced, rendered image,
- and that you have the original object and viewing information regarding the
- rendered scene, it should be possible to derive the original texture map.
- I can think of one fairly simple algorithm that could do it.
-
- What I was wondering is: Has this been done before? Is this a new idea?
- It obviously has more far reaching applications than creating pretty
- pictures, and before I go and start work on something like that, I was
- interested in finding out about previous work in this area.
-
- Any help would be appreciated.
- Al.
