D3DXVec3TransformNormal

The D3DXVec3TransformNormal function transforms the 3-D vector normal by the given matrix.

D3DXVECTOR3* D3DXVec3TransformNormal(
  D3DXVECTOR3* pOut,
  const D3DXVECTOR3* pV,
  const D3DXMATRIX* pM
); 

Parameters

pOut

A pointer to the D3DXVECTOR3 structure that is the result of the operation.

pV

A pointer to the source D3DXVECTOR3 structure.

pM

The pointer to the source D3DXMATRIX structure.

Return Values

A pointer to a D3DXVECTOR3 structure that is the transformed vector.

Remarks

This function transforms the vector normal (x, y, z, 0) of the given vector, pV, by the given matrix, pM.

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec3TransformNormal function can be used as a parameter for another function.
