D3DXVec3Cross
This function determines the cross-product of two 3-D vectors.
D3DXVECTOR3* D3DXVec3Cross(
D3DXVECTOR3* pOut,
CONST D3DXVECTOR3* pV1,
CONST D3DXVECTOR3* pV2
);
Parameters
- pOut
[in, out] Pointer to the D3DXVECTOR3 structure that is the result of the operation. - pV1
[in] Pointer to a source D3DXVECTOR3 structure. - pV2
[in] Pointer to a source D3DXVECTOR3 structure.
Return Values
Pointer to a D3DXVECTOR3 structure that is the cross product of two 3-D vectors.
Remarks
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.
Requirements
OS Versions: Windows CE .NET 4.0 and later.
Header: D3dx8math.h.
