Convert between Euler, quaternion and axis-angle, and blend rotations with slerp — free 3D math tools.
Convert a unit quaternion (x, y, z, w) to roll/pitch/yaw Euler angles, with gimbal-lock detection.
Convert roll/pitch/yaw (degrees) to a unit quaternion (x, y, z, w) for engines, IMUs and animation.
Convert a rotation axis and angle to a unit quaternion — the most intuitive way to specify a 3D rotation.
Spherical linear interpolation between two orientations at parameter t — smooth, constant-speed rotation blending.
Dot product, cross product, the angle between two 3D vectors and whether they're parallel or perpendicular.
Convert between field of view and focal length for cameras, game engines and lenses, for any sensor/film size.
