I send a single point through the pipeline and it gets output in the position (using a vertex with D3DFVF_XYZ) that I thought it would. However when I manually (well really, using D3DXVec3Project) transform the point and output it using a vertex with D3DFVF_XYZRHW it gets put in a position to the upper left of the other point. Can anybody tell me what is the difference between going through the full pipeline and doing D3DXVec3Project (at least as far as final position is concerned, I know D3DXVec3Project will not calculate texture coords, etc.)? Thanks
