The D3DX utility library is deprecated. We recommend that you use DirectXMath instead.
Determines the cross-product of two 3D vectors.
D3DXVECTOR3* D3DXVec3Cross(
_Inout_ D3DXVECTOR3 *pOut,
_In_ const D3DXVECTOR3 *pV1,
_In_ const D3DXVECTOR3 *pV2
);-
pOut [in, out]
-
Type: D3DXVECTOR3*
Pointer to the D3DXVECTOR3 structure that is the result of the operation.
-
pV1 [in]
-
Type: const D3DXVECTOR3*
Pointer to a source D3DXVECTOR3 structure.
-
pV2 [in]
-
Type: const D3DXVECTOR3*
Pointer to a source D3DXVECTOR3 structure.
Type: D3DXVECTOR3*
Pointer to a D3DXVECTOR3 structure that is the cross product of two 3D vectors.
This function determines the cross-product with the following code.
D3DXVECTOR3 v;
v.x = pV1->y * pV2->z - pV1->z * pV2->y;
v.y = pV1->z * pV2->x - pV1->x * pV2->z;
v.z = pV1->x * pV2->y - pV1->y * pV2->x;
*pOut = v;
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec3Cross function can be used as a parameter for another function.
