Re:请教一个得到法线的函数
Returns the normalized version of a 3-D vector.
Syntax
D3DXVECTOR3 *WINAPI D3DXVec3Normalize( D3DXVECTOR3 *pOut,
CONST D3DXVECTOR3 *pV
);
Parameters
pOut
[in, out] Pointer to the D3DXVECTOR3 structure that is the result of the operation.
pV
[in] Pointer to the source D3DXVECTOR3 structure.
Return Value
Pointer to a D3DXVECTOR3 structure that is the normalized version of the specified vector.
Remarks
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec3Normalize function can be used as a parameter for another function.
