First I thought this will be quite straightforward using the volume render (similar to the ironProt.vtk example). However, it appears than in order to use a volume renderer, my data needs to be an image map - which implies structured grid. My data is a large number of (x,y,z) coordinates. </div><div><br></div><div>Question for you, what is the best approach? I can use VertexGlyphFilter (<a
