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?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:24.0pt;font-family:"Monotype Corsiva"'>Chris</span><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Times New Roman","serif"'>--<br>Christopher R.
