[vtkusers] How to retrieve the on-screen x,y coordinates of a 3D actor point?

[Jonathan Bailleul]

Dear all,

I know how to access the points values out of a polydata object used to
make an actor, but can I determine the on-screen projected position of
these points at a given stage of actor visualization?


In advance, thank you for your help.
