[vtkusers] Want to do 3DOF orientation with vtkGlyph3D

[Chris Volpe ARA/SED]

It appears that vtkGlyph3D allows one to orient glyphs that have (nominal, at least) symmetry around one axis, such as vtkCone. What if I want to apply a full 3DOF orientation matrix for each glyph at each point? I realize that specifying both a position and orientation at each occurrence of a glyph can be achieved by using a separate actor for each one, but last time I encountered this situation, VTK incurred a substantial performance penalty when using a large number of actors. And since I don't need any of the other features of multiple actors (e.g. separate material properties), I'd like to avoid doing so if there's a practical alternative. Any suggestions?

Thanks,

Chris
