View Full Version : 3D Rotation

I have been using quaternion mathematics to rotate a 3D model. Initially it works fine but after the model has been rotated, it seems to develop a jitter bug. Has anyone encountered this problem and if so could you tell me what the solution is?

Are you normalising your quaternians properly? Floating point errors? do you do anywhere...

float x;

if (x != 0)
