Does VTK have a filter that will accept vtkPolyData input with scalars and output vtkPolyData with UV coordinates + vtkImageData texture mapped from the scalars? If so what is it called? I have not been able to find such a thing yet. Thanks.
Take a look at vtkScalarsToTextureFilter. It may do some of what you want.
Hope this helps,
After trying this it really just orthogonally rasterizes the polygon onto the plane of best fit. I want to be able to export something like an OBJ of my polygon and texture of it’s scalars. The full scalar information on a texture. For example, tear all the triangles of a mesh apart and pack them into a texture. Then barycentric interpolate the color across each triangle in the texture.
