[Paraview] ParaView v5.3: Generating textures from scalars and lookup table

[David E DeMarle]

Hi Nenand,

You might try vtkMapper::GetColorMapColors/ColorCoordinates/ColorTextureMap.
I'm using this in the OSPRay renderer for example.

Out of curiosity is this for the p2f3d exporter plugin?

cheers
