Hi all, I’m new to the forum and to 3d modeling in general, I know what I want to do, but I’m not 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. Can Blender bake a texture to vertex colors? can you suggest a specific tutorial on this subject? in the documentation I found nothing about it, and in the tutorials I’ve found how to bake vertex colors onto a texture (the opposite of what I want to do).
Otherwise 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.
