Euler angles suffer from Gimbal Lock when pitch reaches 90 degrees. Quaternions represent 3D orientation as a 4D unit sphere (w, x, y, z).

SLERP (Spherical Linear Interpolation) provides smooth constant-angular-velocity transitions between two orientations.

Converting a Quaternion to a 4x4 rotation matrix is very efficient for feeding into graphics projection pipelines.
