Bit of an odd question, but is there a way to estimate the number of pixels that'll be needed to draw an outline of a circle with a given radius? for a = 1 to 360 step ? x = sin(a)*radius y = cos(a)*radius dot x,y next a 'Cause no sense in looping 360 times for a circle with a radius of 2, hardly anything is drawn. It's not really a speed concern I have, but larger circles may take more than 360 pixels to draw it completely without spacing between each dot. So what would be the smaller amount to increment by to complete the circle cleanly? (hope this makes sense)
