D3DXVec2TransformNormal Function

Transforms the 2-D vector normal by the given matrix.

Syntax

D3DXVECTOR2 *WINAPI D3DXVec2TransformNormal(      

    D3DXVECTOR2* pOut,
    CONST D3DXVECTOR2 *pV,
    CONST D3DXMATRIX *pM
);

Parameters

pOut

[in, out] Pointer to the D3DXVECTOR2 structure that is the result of the operation.

pV

[in] Pointer to the source D3DXVECTOR2 structure.

pM

[in] Pointer to the source D3DXMATRIX structure.

Return Value

Pointer to a D3DXVECTOR2 structure that is the transformed vector.

Remarks

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

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec2TransformNormal function can be used as a parameter for another function.
