Two Questions: 1. I am working on a globe that I created work. I have created the globe with the texture. I also rotated the globe -90 degrees and the x-axis and 90 degrees around the z-axis to get the orientation right. Now that I rotated my scene -90 degrees around the x-axis my y-axis has now become my z-axis and vice versa. So how do I correct my orientation to show true x,y and z axis without disturbing the orientation of the globe that I created? 2. Are there any good tutorials out there for moving objects in a scene in six degrees of freedom? IE Zoom in and Out, rotate about the x and y axies, and translated the object to any coordinate location in the scene? Any help would be greatly appreciated! Thanks!

you don''t need quats for this. just use a regular matrix, but when you go to rotate it, multiply the rotation vector by the matrix.

What I want to do is the mouse movement of objects similar to what was done in this demo.
