In fact, object's partial plane must be

mapped to the pixel.

Is it right???

Because the dot must be ideally a zero area.

Anyway, window coordinates in openGL

mean pixels. And we convert the window coordinate

value to world coordinate via gluUnproject()

But this mapping is one to one.

(plane's center point(maybe I think) to pixel)

My problem is that I want to know

four coordinate values(vertices)

mapped to one pixel.

How can I obtain four vertices(world coordinate) mapped to one pixel?

Please Help me!!!
