Using Quaternions for OpenGL Rotations http://stackoverflow.com/questions/9715776/using-quaternions-for-opengl-rotations smoothly through 3D space. After messing around with Euler angles a bit it seems they aren't really appropriate for free form.. 1 Capture Input I figured it would be best to use Euler angles or a Pitch Yaw Roll scheme for capturing player input. At the.. best to just build a new quaternion from updated Euler angles or whether I'm supposed to multiply the quaternion representing..
