I am trying to render lots of cylinders and would like to use vtkOpenGLStickMapper instead of glyphs to see if it is more performant. However I can’t figure out how to use vtkOpenGLStickMapper. I am just giving it polydata with a bunch of points but every time I go to render, I get a segfault. I assume it needs specific data fields, or named arrays?
Do I have to use the vtkOpenGLMoleculeMapper and a vtkMolecule instead?
