I'm kind of new to this, what does VPOS mean? I set the view and projection matrices when initializing Direct3D.  Then when rendering I do this:       World = i->second->getTransform() * m_BufferToWorld;       hr = m_pD3DDevice9->SetTransform(D3DTS_WORLD, ...

Hi everyone, I have the vertex of an object and I would like to calculate what the pixel coordinate will be in my backbuffer.  I tried to multiply the homogenous coordinate by the product of multiplying World * View * Projection matrices, but that doesn't work.  If I leave out the projection matrix it works perfectly for points ...
