D3DXVec2TransformCoord

The D3DXVec2TransformCoord function transforms a 2-D vector by a given matrix, projecting the result back into w = 1.

D3DXVECTOR2* D3DXVec2TransformCoord(
  D3DXVECTOR2* pOut,
  const D3DXVECTOR2* pV,
  const D3DXMATRIX* pM
); 

Parameters

pOut

A pointer to the D3DXVECTOR2 structure that is the result of the operation.

pV

The pointer to the source D3DXVECTOR2 structure.

pM

The pointer to the source D3DXMATRIX structure.

Return Values

A pointer to a D3DXVECTOR2 structure that is the transformed vector.

Remarks

This function transform the given vector, pV (x, y, 0, 1), by the given matrix, pM, projecting the result back into w=1.

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec2TransformCoord function can be used as a parameter for another function.
