<DIV>I recently started working with VTK. I have a mesh that represents a face
in 3D and my goal is to deform it by picking points (control points of the mesh)
and moving with the mouse. I am not really sure if there is a class that will
allow me to do that easily or if I have to use callbacks I implement myself to
track the start and end positions...In general, the easiest way to implement a
mouse listener is to go through the interactor, its observer and a callback
function?</DIV>
<DIV>Thanks for your time...</DIV>
