Algodoo

Nicely done nikol. Now tell us how you did it.

Thanks! It is based on Discrit Fourier Transformation. It says that any line can ba approcsimated whit set of COS and SIN. I have written a program in Python in which i can draw lines or load ready CSV-file.
Then the program do Discrit Fourier Transformation and calculates the sizes and initial angles of boxes.
Then the program generates PHN-file for Algodo. It is simple

OK, I'm impressed. I understand and believe most of what you are saying, except for "It is simple.". If I understand correctly the process works like this:
1. Get a drawing in the form of discrete equally spaced values.
2. Do a DFT on the drawing.
3. Take the resulting list of frequency, phase, and amplitude values and convert each item into motor speed, initial angle, and link length.
4. Connect all the links together.
5. Put a tracer on the end of the last link.

I'm not sure how the DFT works with lines that reverse in the x (or time) direction, but I guess that all just works out.

By the way: I've programmed in Python and find it to be the most straightforward and concise language.

Yes. That is the right way that you have described.

s_noonan said: "Get a drawing in the form of discrete equally spaced values."

Where would I find such a drawing, and how would I know whether or not it has "discrete equally spaced values"?

This is a parametric line. We assume that the first point is t=0 and the last point is t=1. If there are 5 points in the line, then we have t=0, t=0.25, t=0.5, t=0.75, t=1. I. e they are equidistant from each other by 0.25

nikol,

In my 4ier Series Robot scene, I do what you have described by using chain link locations which automatically space out the points along the single line. I think that Xray was not asking how to do it but where can he find a drawing that contains a list of data points. When I was creating my scene, I could not find such a drawing. Where did you find the drawing used in your drawing mechanism 1000 boxes and axels scene? Did you draw it yourself? Did you find it somewhere on the web?

I drew this myself in my program. This program allows you to draw lines point by point, insert points, or delete points. Then you can save a set of points or generate an algodoo-file.

OK. Thanks. Yo must be good at programming with Python.
