In fact, driving geometry is much simpler than coloring a mesh. Since i think (maybe someone can help me here) there's no way of getting the uv coordinates of a point in 3d space on a projected surface, you need to do some scripting to order the sample points that are closer to each vertex of the mesh and create a parallel list of curvature numbers that coincide with the number of vertices and is in the right position.
I guess there's no way of finding the equivalent uv of a point in 3d space, even if it was projected on a surface, because once it's in world coordinates there's probably some rounding errors that makes it not exactly on the surface. Nevertheless, could the project component have an uv ouptut?
