operator*= function (directxmath.h)
Multiplies one XMVECTOR instance by a second instance, returning a reference to the updated initial instance.
operator *= multiplies each component of the current instance of XMVECTOR Data Type by the corresponding component in a second specified instance of XMVECTOR, returning a reference to the updated initial instance.
XMVECTOR &XM_CALLCONV noexcept operator*=( XMVECTOR & V1, FXMVECTOR V2 );
Reference to current instance of XMVECTOR.
XMVECTOR instance whose components are to be multiplied against the corresponding elements of V1.
Reference to the updated current instance of XMVECTOR containing the result of the multiplication operation.
The following pseudocode demonstrates the operation of this operator:
XMVECTOR V1; XMVECTOR V2; V1.x = V1.x * V2.x; V1.y = V1.y * V2.y; V1.z = V1.z * V2.z; V1.w = V1.w * V2.w;
