Code:

void CalcScreenCoors ( D3DXVECTOR3 *vecWorld, D3DXVECTOR3 *vecScreen )
{
        /** C++-ifyed function 0x71DA00, formerly called by CHudSA::CalcScreenCoors **/
        // Get the static view matrix as D3DXMATRIX
        D3DXMATRIX      m ( (float *)(0xB6FA2C) );

        // Get the static virtual screen (x,y)-sizes
        DWORD           *dwLenX = ( DWORD * ) ( 0xC17044 );
        DWORD           *dwLenY = ( DWORD * ) ( 0xC17048 );

        //DWORD *dwLenZ = (DWORD*)(0xC1704C);
        //double aspectRatio = (*dwLenX) / (*dwLenY);
        // Do a transformation
        vecScreen->x = ( vecWorld->z * m._31 ) + ( vecWorld->y * m._21 ) + ( vecWorld->x * m._11 ) + m._41;
        vecScreen->y = ( vecWorld->z * m._32 ) + ( vecWorld->y * m._22 ) + ( vecWorld->x * m._12 ) + m._42;
        vecScreen->z = ( vecWorld->z * m._33 ) + ( vecWorld->y * m._23 ) + ( vecWorld->x * m._13 ) + m._43;

        // Get the correct screen coordinates
        double  fRecip = (double)1.0 / vecScreen->z;    //(vecScreen->z - (*dwLenZ));
        vecScreen->x *= (float)( fRecip * (*dwLenX) );
        vecScreen->y *= (float)( fRecip * (*dwLenY) );
}
