D3DXPlaneNormalize function (D3dx9math.h)

Normalizes the plane coefficients so that the plane normal has unit length.

Syntax

D3DXPLANE* D3DXPlaneNormalize(
  _Inout_       D3DXPLANE *pOut,
  _In_    const D3DXPLANE *pP
);

Parameters

pOut [in, out]

Type: D3DXPLANE*

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

pP [in]

Type: const D3DXPLANE*

Pointer to the source D3DXPLANE structure.

Return value

Type: D3DXPLANE*

Pointer to a D3DXPLANE structure that represents the normal of the plane.

Remarks

This function normalizes a plane so that |a,b,c| == 1.

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