Public Methods

Method	Description
FromEuler ( double heading, double attitude, double bank ) : void	constructor to create vecRotation from euler angles.
Normalize ( ) : void
VecRotation ( ) : System	Default constructor - initializes all fields to default values
VecRotation ( double x, double y, double z, double angle ) : System
combine ( VecRotation r ) : void	calculate total rotation by taking current rotation and then apply rotation r if both angles are quaternions then this is a multiplication
combine ( double heading, double attitude, double bank ) : void	combine a rotation expressed as euler angle with current rotation. first convert both values to quaternoins then combine and convert back to axis angle. Theory about these conversions shown here: http://www.martinb.com/maths/geometry/rotations/conversions/index.htm
getTransform ( Fractrace.Geometry.Vec3 p1 ) : Fractrace.Geometry.Vec3	calculates the effect of this rotation on a point the new point is given by=q * P1 * q' this version does not alter P1 but returns the result. for theory see: http://www.martinb.com/maths/algebra/realNormedAlgebra/quaternions/transforms/index.htm
toEuler ( double &heading, double &attitude, double &bank ) : void	Converts the Rotation in Euler Axis

Protected Methods

Method	Description
toAxisAngle ( ) : void	if this rotation is not already coded as axis angle then convert it to axis angle
toQuaternion ( ) : void	if this rotation is not already coded as quaternion then convert it to quaternion
