opengl matrix rotation quaternions

Question

Im trying to do a simple rotation of a cube about the x and y axis:

I want to always rotate the cube over the x axis by an amount x and rotate the cube over the yax

Answer 1

Your problem is not the gimbal lock. And effectively, there is no reason why your quaternion version would work better than your matrix (glRotate) version because the quaternions you are using are mathematically identical to your rotation matrices.

If what you want is a mouse control, you probably want to check out arcballs.
