QUATERNION AND ITS APPLICATION IN COMPUTER ANIMATION
The rotations of rigid objects are described by a four coordinate system called quaternion. The properties of quaternion are introduced.Two formulae for spherical quaternion linear interpolation are offered.A smooth quaternion inbetweening technigue is proposed based on the cubic cardinal-spline curve.An intuitive understanding of the role of quaternion in rendering is given.
