Syntax

void VectorQuaternionMultiply
(
    void *RESTRICT Result,
    const void *RESTRICT Quat1,
    const void *RESTRICT Quat2
)

Remarks

Multiplies two quaternions; the order matters.

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

Parameters

Parameter	Description
Result	Pointer to where the result Quat1 * Quat2 should be stored
Quat1	Pointer to the first quaternion (must not be the destination)
Quat2	Pointer to the second quaternion (must not be the destination)
