- THE CHAOS GAME
- ▄▄▄▄▄▄▄▄▄▄▄▄▄▄
-
-
- One of the discoveries of the new science of Chaos is that there seems to be
- an underlying order in randomness. Applying the simple rule of plotting a
- point from a starting position - halfway to a randomly chosen vertex of an
- arbitrary triangle, using the new point as the next beginning, and repeating
- produces a strikingly orderly pattern. This so-called Sierpinsky Gasket
- is a figure with a dimension of less than two, a fractal dimension.
-
- Type SIER and see the triangle drawn, the "seed" point circled. This point
- may be inside or outside the triangle, it matters not. Watch as the pattern
- becomes illuminated in different colors showing which of the vertices has
- been selected for any given plotted point.
-
- The source code in the file SIER.C is made available for C programmers who
- wish to do their own tinkering with the patterns. The file SIER_1.C is
- source code for those wishing to try a variation, using an extra
- "attractor" inside the triangle. The resulting pattern at first appears
- more chaotic, but soon resolves itself into a visually interesting orderly
- pattern.
