Should the function that does this be a member of TCVector?

Also, could you rewrite the function? I am not familiar with C++ syntax.

I just realized that you're converting angles to a matrix, and then trying to extract those same angles out of the matrix. This isn't going to help. Rotations are always in the local coordinate system, whatever that happens to be. (More specifically, all 3D transformations are relative to the currently active local coordinate system at the time the transformation is applied.) When you tell my camera to rotate, it does so in its own local coordinate system.

I'm not sure it will work, but try calculating how far you need to rotate around X for Y to point straight up. Store this in deltaY. Rotate around X by that amount, then rotate around Y by the desired X rotation amount, then rotate around X by -deltaY + the desired Y rotation amount.

Note that the X and Y rotations above are inverted intentionally. If you want to turn your head left or right (X rotation amount), you rotate around the Y axis. If you want to nod your head up and down (Y rotation amount), you rotate around the X axis.
