Hi,
I'd like to create a piece of geometry with a texture that is dynamically generated based on the (s, t) texture coordinate being read. The intent is to allow me to create a terrain texture which will return a road texture on the bits of terrain that shold have roads, grass in the bits that have grass and rock in the bits that have rock. I can't create a single texture before hand because it would be huge, but I can automatically generate the correct 2D texture using a class I've developed (you can request of this call any rectangular area and it will return the correct 'map' for that section). I've considered using multiple textures, but there seems to be no way for me to integrate my distinct texture maps the way I'd like using a purely 3D process.
Another example would be: is there a way to texture a Mandlebrot set on a piece of geometry without prerendering the image of the set?
Is there any way to do this? Will the programmable shaders provide this ability when implemented?
