The D3DXVec4Lerp function performs a linear interpolation between two 4-D vectors.
D3DXVECTOR4* D3DXVec4Lerp( D3DXVECTOR4* pOut, const D3DXVECTOR4* pV1, const D3DXVECTOR4* pV2, float s );
A pointer to a D3DXVECTOR4 structure that is the result of the linear interpolation.
This function performs the linear interpolation based on the following formula: V1 + s(V2-V1).
The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXVec4Lerp function can be used as a parameter for another function.
