D3DXPlaneFromPoints

The D3DXPlaneFromPoints function constructs a plane from 3 points.

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

Parameters

pOut

A pointer to the D3DXPLANE structure that is the result of the operation.

pV1

A pointer to a D3DXVECTOR3 structure. This is one of the points used to construct the plane.

pV2

A pointer to a D3DXVECTOR3 structure. This is one of the points used to construct the plane.

pV3

A pointer to a D3DXVECTOR3 structure. This is one of the points used to construct the plane.

Return Values

A 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.
