Didn't know that article you linked to, interesting -- though I don't see why I would use 0.375 in practice. At least I never ran into a case where it was required, but it's good to know -- thanks!

Didn’t know that article you linked to, interesting — though I don’t see why I would use 0.375 in practice. At least I never ran into a case where it was required, but it’s good to know — thanks!

It is also mentioned here: http://msdn.microsoft.com/en-us/library/dd374282(VS.85).aspx That way, I don't need to make the correction directly on the vertex coordinates. I like OpenGL but I have my eyes on what is coming with DX11! After setting the orthogonal projection, I take care of the pixel correction by adding 0.375 in the modelview matrix.
