D3DXVec3Cross

The D3DXVec3Cross function determines the cross-product of two 3-D vectors.

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

Parameters

pOut

A pointer to the D3DXVECTOR3 structure that is the result of the operation.

pV1

A pointer to a source D3DXVECTOR3 structure.

pV2

A pointer to a source D3DXVECTOR3 structure.

Return Values

A 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.
