since two ends of a continuous interval do not necessarily completely overlap with the Hilbert curve segments, this argument controls how to determine the ends of the interval which will be presented on the curve. |
Drawing polygons are quite similar as drawing rectangles in the context of Hilbert curve. The major difference is: 1) for rectangles, colors for the ends of the interval can change if they are not completely covered by the segments, and 2) polygons can have borders.
Basically polygons are used to mark areas in the Hilbert curve.
No value is returned.
