Syntax

VectorRegister VectorQuaternionMultiply2
(
const VectorRegister & Quat1,
const VectorRegister & Quat2
)

Remarks

Multiplies two quaternions; the order matters.

Order matters when composing quaternions: C = VectorQuaternionMultiply2(A, B) will yield a quaternion C = A * B that logically first applies B then A to any subsequent transformation (right first, then left).

Returns

Quat1 * Quat2

Parameters

Parameter	Description
Quat1	Pointer to the first quaternion
Quat2	Pointer to the second quaternion
