D3DXPlaneFromPoints function

Constructs a plane from three points.

Syntax


D3DXPLANE* D3DXPlaneFromPoints(
  _Inout_  D3DXPLANE *pOut,
  _In_     const D3DXVECTOR3 *pV1,
  _In_     const D3DXVECTOR3 *pV2,
  _In_     const D3DXVECTOR3 *pV3
);

Parameters

pOut [in, out]

Type: D3DXPLANE*

Pointer to the D3DXPLANE structure that is the result of the operation.

pV1 [in]

Type: const D3DXVECTOR3*

Pointer to a D3DXVECTOR3 structure, defining one of the points used to construct the plane.

pV2 [in]

Type: const D3DXVECTOR3*

Pointer to a D3DXVECTOR3 structure, defining one of the points used to construct the plane.

pV3 [in]

Type: const D3DXVECTOR3*

Pointer to a D3DXVECTOR3 structure, defining one of the points used to construct the plane.

Return value

Type: D3DXPLANE*

Pointer to the D3DXPLANE structure constructed from the given points.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXPlaneFromPoints function can be used as a parameter for another function.
