Hi,
I am trying to implement a feature to select a set of points in a 3dViz window using the mouse. However, I am unable to lock the rotation of the point set (i.e. viz::WCloud).
What I would like to achieve is to have the usual mouse interaction in typical conditions (e.g. rotation with the left-hand button, scroll, etc.), but when I press a button (e.g. 'a'), the rotation interaction that gets triggered when the left-hand button is pressed becomes a selection tool, like a rectangular region.
I can't figure out how to implement this. Can anyone help me with this?
Cheers
