E3dQuaternion_ToAxisAngle

Convert a quaternion to an axis-angle rotation

Syntax
void E3dQuaternion_ToAxisAngle(const E3dCoord4* PQuaternion, E3dCoord4* PAxisAngle)

Arguments
PQuaternion The destination Matrix PAxisAngle The axis-angle rotation as a Coord4
Description
Converts an axis-angle rotation to a Quaterion.
With the angle of rotation Angle, the Quaternion is of the following form:

   X, Y, Z:  coordinates of the axis of rotation
   W:        Angle as degrees

Return value
None.
