D3DXVec4Transform

The D3DXVec4Transform function transforms a 4-D vector by a given matrix.

D3DXVECTOR4* D3DXVec4Transform(
  D3DXVECTOR4* pOut,
  const D3DXVECTOR4* pV,
  const D3DXMATRIX* pM
); 

Parameters

pOut

A pointer to the D3DXVECTOR4 structure that is the result of the operation.

pV

A pointer to the source D3DXVECTOR4 structure.

pM

A pointer to the source D3DXMATRIX structure.

Return Values

A pointer to a D3DXVECTOR4 structure that is the transformed 4-D vector.

Remarks

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec4Transform function can be used as a parameter for another function.
