With vtkGlyph3d I’m able to visualize points as spheres with constant “screensize” by using SetScaleModeToScaleByScalar and vtkDistanceToCamera to generate the distance scalars. Another point representation I want to realize is a local oriented triad on each point. Because of the orientation issue I have to use vtkTensorGlyph with tensor data for the triad directions. Everything works fine, except the scaling of the glyphs. I’d like to have a constant size of the triads with respect to the screen but until now I couldn’t find a way. Did I miss something?
Or is there another maybe slower way via data manipulation (scaling the tensor data with scalars from vtkDistanceToCamera)
