10.6

As a learning exercise I decided to put together a QC version of Michael Barnsley's Chaos Game.

The game is simple. Take an equilateral triangle with each vertex colored differently. I used red for the apex, green for the lower left, and blue for the lower right. Then specify a random point. From that point, choose a random vertex and plot the point half-way from the starting point to the vertex. Choose another random vertex, and plot the point half-way between the last point and the new vertex. Repeat across n iterations.

Usually the guess of what this will produce is either "a mess" or "a triangle", but, as Michael Barnsley discovered, it creates a beautiful fractal known as the Sierpinski Triangle, which is a fractalization of equilateral triangles.

Here is the comp. MUCH THANKS to cybero, smokris, gtoledo3, jersmi, and everyone else who chimed in, and stuck with me through a painful learning curve.

I'd love to hear any comments, enhancements, optimizations, etc. that anyone has to offer.

One thing I tried to do, since the QC work I am doing at work involves creation of componentry, was to create macros, and reusable bits. Please feel free to cannibalize this thing and use whatever you'd like in your own work.

Cheers,

Chris

hex2color macro makes RGB color from 6 character hex string (WebColor) with javascript.

A simple composition, draw lines like the mouse moves, draws a circle when mouse not moved after 1sec.

Iterates a structure derived from .DAE files normals members.

DAE structure member is fed from Structure Index patch to Mesh Iterator, with the Structure Member count providing an Iterations count inside the macro.

Resulting render is an iterated 3d render of the meshes normals.

The attached demo uses both Mesh Iterator by Structure - Vertices and Mesh Iterator by Structure - Normals.

The DAE file - from collada.org, has also been uploaded so you can properly run the demo in full.
