SIQuaternion.Mul
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 ); |
