<P><FONT SIZE=2>Hi all,<BR>
<BR>
The member methods of vtkActor2D class contains method for placing the actor in different coordinate systems like world coordinates and display coordinates so on and so forth.<BR>
<BR>
If I want to label the vertices of my polyhedron to help me with my geometry related debugging how do I transform my 3D point coordinates(vertices) into the 2D coordinates which is accepted by the methods of vtkActor2D instance.<BR>
<BR>
I'am not all that familiar with the differences between different coordinate systems any pointers to the relevant material will be highly appreciated.<BR>
<BR>
Thanks,<BR>
