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.
Link Library: D3dx8.lib.
