D3DXPlaneNormalize

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

D3DXPLANE * D3DXPlaneNormalize(
  D3DXPLANE * pOut,
  CONST D3DXPLANE * pP
);

Parameters

pOut

[in, out] Pointer to the D3DXPLANE structure that is the result of the operation.

pP

[in] Pointer to the source D3DXPLANE structure.

Return Values

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.

Requirements

Header: Declared in D3dx9math.h.
