How is a circle generated?

A circle is formed when the plane is parallel to the base of the cone. Its intersection with the cone is therefore a set of points equidistant from a common point (the central axis of the cone), which meets the definition of a circle.

What will happen if PK 0?

i.e., Pk<0, means that midpoint is inside the circle boundary, so the circle boundary is close to the upper pixel, thus choose the upper pixel (xk+1, yk) for plotting, otherwise if Pk>0, the midpoint is outside the circle boundary, so the circle boundary is close to the lower pixel, thus choose the lower pixel (xk+1, …
