D3DXVec3Subtract

Subtracts two 3D vectors.

D3DXVECTOR3 * D3DXVec3Subtract(
  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 difference of two vectors.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec3Subtract function can be used as a parameter for another function.

Requirements

Header: Declared in D3dx9math.h.
