[Paraview] POV Exporter, spheres/geom/colors

[Heiland, Randy]

I have a simple 2-point Pgmable Source (below) and render it 1) as 2D Glyphs/Vertex (with the nice OSPRay, and scaled spheres), and 2) as various 3D/geometric glyphs. Then I Export the scenes as POV files. Only the geometric (non 2D/Vertex) glyphs generate partially-meaningful POV output. However, there’s no color associated with the geometry. Thoughts?

The last related thread I saw was at:
