[vtkusers] 2D overlay on 3D visualization

[Tijmen Klein]

Hello everyone,

I'm working on a multitouch application for VTK. A 3D dataset is visualized
on the screen, and the multitouch input is used for the interaction. I want
to draw the current locations of the touches as a 2D overlay, so that the
user(s) know which touches are recognized. What would be the best and
easiest way to draw up to 10 points/circles in 2D on top of the 3D
visualization?

Cheers,
Tijmen
