Examples of Quaternion

com.ardor3d.math.Quaternion
Quaternion represents a 4 value math object used in Ardor3D to describe rotations. It has the advantage of being able to avoid lock by adding a 4th dimension to rotation. Note: some algorithms in this class were ported from Eberly, Wolfram, Game Gems and others to Java.

Quaternion defines a single example of a more general class of hypercomplex numbers. Quaternions extends a rotation in three dimensions to a rotation in four dimensions. This avoids "gimbal lock" and allows for smooth continuous rotation. Quaternion is defined by four floating point numbers: {x y z w}. @author Mark Powell @author Joshua Slack
