*** Oh ok. It is in fact a routine to project a point. Intstead of using 
that function, try something along the lines of:

void _projectVector(POINT projectMe)
{
    if(!projectMe.z)                   // the vector is sans z-magnitude
    {
       plotPixel(projectMe.x,projectMe.y,projectMe.color);
       return;
    }

    else
    {
       int projectX = /* caluclations go here */;
       int projectY = /* caluclations go here */;
       plotPixel(projectX,projectY,projectMe.color);
       return;
    }
}

*** Besides that, I am not sure what else to say. To try to hunt down the 
problem, be sure that you can plot regular points; Once you have concluded 
that you can do so, then concentrate on implementing a z attribute. Have 
fun, building your engine. I am also in the process of doing so as well, so 
I understand.
