[vtkusers] picking a voxel in a MIP volume

[Mark Wyszomierski]

Hi,

I'm doing a MIP rendering. Is there a way to 'pick' a voxel in the
rendered volume? I was thinking that the user could click a voxel in
the MIP volume, then I could display the picked voxel's x,y,z
location. Is this possible?

Thanks,
Mark
