If UV mapping were to be implemented in POV , which of the following would you
prefer?
1) regular vs. UV mapping is set for each OBJECT
2) regular vs. UV mapping is set for each PIGMENT, TEXTURE, or NORMAL.
-------------------
Choice (1) example:
bicubic_patch
{
...
uv_mapping
texture { NeatWoodTexture }
}
-------------------
Choice (2) example:
bicubic_patch
{
...
texture { uv_mapping NeatWoodTexture }
}
-------------------
Choice (2) would be more flexible, but creates some interesting questions when
you get into more complicated textures (like texture averages, layered
textures, and texture_map stuff). With choice (2), you could do fun things
like a normal 3D wooden texture with a UV-mapped dirt texture over it.
Choice (2) is also a bit more difficult to impliment (what I've got now is
probably full of bugs, but it looks really cool).
I personally think that choice (1) is much cleaner and will likely cause fewer
problems overall. I also don't think that it is overly restricting.
Comments?
