D3DXVec3Cross function

Determines the cross-product of two 3D vectors.

Syntax


D3DXVECTOR3* D3DXVec3Cross(
  _Inout_       D3DXVECTOR3 *pOut,
  _In_    const D3DXVECTOR3 *pV1,
  _In_    const D3DXVECTOR3 *pV2
);

Parameters

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.

Return value

Type: D3DXVECTOR3*

Pointer to a D3DXVECTOR3 structure that is the cross product of two 3D 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.
