This node computes the texturing on the mesh.
|
|
|
|
If the mesh has no associated UV, it automatically computes UV maps.
|
|
|
|
For each triangle, it uses the visibility information associated to each vertex to retrieve the texture candidates.
|
|
It select the best cameras based on the resolution covering the triangle. Finally it averages the pixel values using multiple bands in the frequency domain.
|
|
Many cameras are contributing to the low frequencies and only the best ones contributes to the high frequencies.
