Hi,

I have a simple question which puzzles me for several days.
The function named computePosition in the trackball manipulator CPP.
The last line it discribes as  _rotation = 
rotation_matrix.getRotate().inverse();
Could anybody tell me why the matrix need to inverse in detail?

Thank you! :) 

Cheers,
Robert.Huang
