TRUE software is a freeware since March 2013

The animation below is an assemblage of OpenGL primitives.

In this example :

  • the first wheel leads the second
  • the second wheel leads the third
  • the radius and the position of the second wheel are varying over time
  • the rotation speed of the third wheel follows

    Values have been calculated by the System Dynamics software True.


  • An other animation : a spider

  • The legs are made with bones dressed by particules
  • The body is made with a teapot
