I have a Picture 3D Control in my project.By default, the application will handle the mouse events on the Picture3D Control as follows: Left mouse button = RotateSHIFT + Left mouse button = ZoomCTRL + Left mouse button = Translate However, users of our applications have become familiar with a different mouse mapping: Left mouse button = RotateRight mouse button = TranslateCenter mouse button or scroll wheel = Zoom I have been unable to find a method or an example (on NI support or Developer Zone) showing me how I can change the mouse behaviour in the Picture 3D control.I have been able to catch mouse events and handled the scroll wheel, but the other functionality remains as is. Any help would be greatly appreciated. EDIT: I am using LabView 8.2 on Windows XP Message Edited by ccmonter on 11-11-2009 04:47 PM

Last update for ModelViewMatrix, if people are still confused these two links will prove useful.

The second link explains why you need to divide/multiply (however you interpret it) the matrices to get proper (x,y,z) cartesian coordinates.
