My quesion is about the pixel rendering under the special circumstance:
what will happen when the object size is smaller than the size of the pixel?
Suppose that we draw a cylinder in the diagonal direction. The size of cylinder is so small that it is shown in the monitor as a line. But what I saw is a dotted line. I think that it is kind of scaling problem. Some pixels are turned on but some are not. Why is that? Anyone can give me a clear explanation? What is the mechanism behind to determine which pixles can be turned on and which ones can not? Is there any way to eliminate it?
