In my Pgmable Source PolyData, I render Points and love the OSPRay-rendered spheres. However, is there any mechanism for (independently) scaling these, i.e., other than the fixed Point Size? Or is the only way to get scalar-value scaled spheres via the Glyph filter? If so, is it possible to control the resolution/triangulation of that glyph? Basically, I’m looking for ways of getting high-res spheres, but will also want to use vtkCutter on them later.<br>
