- Here's a little problem which has been bugging me for a while. I hope
- someone here can provide a work-through for me:
-
- Given: - a rectangular coordinate system, raster display.
- - A circle, of radius r, and a straightforward drawing algorithm,
- assuming averaging elimination of round-off errors.
-
- What is the minimum number of discrete points that will exist in the
- perimeter of that circle? And, of more interest, if one has a minimum
- number of points required, what will be the minimum radius needed to
- produce that number?
-
- I'm looking for something along the lines of a mathematical proof.
-
- Apologies if this is blindingly obvious, but I don't see a simple solution.
- If someone could point me in the right direction, I'd appreciate it.
