Multiplies the quaternion q1 by the quaternion q2 and stores the result in this quaternion: this = q1 . q2

When used in the context of rotation this operation has the effect of adding two rotations.

SIQuaternion.Mul( SIQuaternion in_pQuat1, SIQuaternion in_pQuat2 );

SIQuaternion.Mul( q1, q2 );

Parameter	Type	Description
q1	SIQuaternion	quaternion operand
q2	SIQuaternion	quaternion operand

' Create Quaternions.
set q1 = XSIMath.CreateQuaternion(1.0, 1.0, 2.0, 3.0)
set q2 = XSIMath.CreateQuaternion(1.0, 4.0, 5.0, 6.0)
set q3 = XSIMath.CreateQuaternion
'q3 = q1 . q2
q3.Mul q1, q2
