Hi all, some time ago I posted a similar question on max-specific forum, then I suspended my research. I'm again looking for this technique, possibly with a cheaper program than 3ds max. Note: I'm not even sure I'm using the correct terms.
I need to create terrain models to use them in a real time visualization, I can't use large textures, so I would like to color the vertices of these models from a landsat image (obviously the models will have enough vertices to produce a decent result).
First: is this technique called "light baking"? or "texture baking"? or "vertex color baking"?
Second: I asked in many other application-specific forums on how to do this with that package, it seems that the ability to assign vertex colors from a bitmap is quite uncommon! So far I've found that only Lightwave and 3ds Max can do that, but I was looking for something much cheaper.
I was suggested to look at XSI for its Ultimapper tool, which can do what I was looking for, can you confirm this is the right tool? I got no answers on XSI forum. Any other suggestions regarding 3d modeling packages with this feature?
Here's a link to a movie made from Lightwave, in the first part of the movie you can see what I'm looking for: the guy takes a shape, it applies a bitmap to the vertex colors and then subdivides the mesh getting very close to the original bitmap drawing. In lightwave this is called "textured point".

Do you have other suggestion on how to obtain this result? I have to use as much real geometry as possible, because the point of view will be very close to the terrain.
Thanks
Marco
