Download Parametric Four Orbit Generator

The Parametric Four Orbit Generator© for MS Windows is for educational purposes. It simulates the behavior of four objects in Newtonian space. The smaller the 'Delta Time' parameter the higher the resolution of computation per unit time. So therefore, the objects move more slowly but more accurately. This program can simulate real solar systems with the proper parameters. It has the resolution to create real results with the sacrifice of speed. Write down the parameter numerics you like for reuse. The 'Return' and 'Enter' Keys will operate as the 'Compute' Button. The 'Escape' key will operate as the 'Stop' Button.

Download Maximum Connectivity Demonstrator

The Maximum Connectivity Demonstrator© for MS Windows is for educational purposes. It demonstrates and displays the behavior of interconnected nodes. The parametric edit fields allow manipulation of the level of connectivity between nodes. By zooming to a node, one may explore the granularity of connectivity. The 'Return' and 'Enter' Keys will operate as the 'Compute' Button. The 'Escape' key will operate as the 'Stop' Button.

Download Parametric Rossler Oscillator Generator

The Parametric Rossler Oscillator Generator© for MS Windows is for educational purposes. It demonstrates and displays the behavior of the Order of Chaos for two coupled oscillators which simulates the bioelectric behavior of the Heart. The parametric edit fields allow manipulation of the variables in the differential equation which models the oscillators. By scaling, and using Phi and Theta fields one may explore this non-linear chaos.

Non-Linear Formula

Delta x/Delta t = -Y -Z
Delta x/Delta t = X + Y / A
Delta x/Delta t = (1 / B) + Z * (X - C)
Download Parametric Duffing Oscillator Generator

The Parametric Duffing Oscillator Generator© for MS Windows is for educational purposes. It demonstrates and displays the behavior of the Order of Chaos for two coupled oscillators. The parametric edit fields allow manipulation of the variables in the differential equation which models the oscillators. By scaling, and using Phi and Theta fields one may explore this non-linear chaos.

Non-Linear Formula

Delta x/Delta t = Y
Delta x/Delta t = ( - ((A * (X * X * X)) + (C * X) + (B * Y))) + (F * Cos (Z))
Delta x/Delta t = 1

Download Parametric Rodin Torus Generator

Now saves DXF of Geometry.

Based on a template circle, of 80 units in radius, vectors are drawn to resemble the trajectories of the windings of the Rodin torus. The are vectors spaced around the circle at 30 degree increments. A circle was drawn with a radius of 22. However it does not fall into tangency with the inside radius of the windings. CAD drafts show that it is a radius of 20.6875 units. The bisector of this radius is 50.375 not 51.

Based on this assumption, I created a program that created the trajectory of a sine wave around a torus. With a center trajectory diameter of 50.375 and a radius of 80 minus 20.6875 divided by 2 which equals 29.6875.

The algorithm uses a trick to simulate the proper quantity of turns in the winding. A complete 360 degree rotation of the sine wave is completed in 300 degrees of radius of the torus. 300 divided by 360 is .83333333 or 5 over 6. So by modifying the code to the algorithm to create a complete rotation of the sine wave in just 300 degrees of the torus, a primary building module of the complete winding can be created.

The parametric equation for a Toroidal Spiral is:
x = (a * sin (c * t) + b) * cos (t)
y = (a * sin (c * t) + b) * sin (t)
z = a * cos (c * t)
a = 29.6875
b = 50.375
c = 2 (number of turns)

This is obviously not a simple task. My extensive experience in coding parametric equations allowed me to create a quick solution. I achieved a modest level of success. I can control all parameters of the spiral and the resolution of the trajectory to achieve the observed effect.
