hi there,
i wonder which program is able to visualise the orbit of a point in the complex plane ?! as far as i know ultrafractal can not do it ....
would love to demonstrate the listeners of my seminar the process of orbits
Ultrafractal can do anything !!
mmf4.ufm-Attractors
Default is Mandelbrot mode - using the switch by default displays the orbits but you can change this between Julia and Orbits.
** Read the help text at the top of the paramaeters **
Edit: I forgot - after switching to the orbit view change the main UF max. iterations to 1 and set the inside colouring to black - also increase the max. hits ans orbit iterations in the formula - here's a good one to switch from to start with:

The above is the Mandy for the standard Henon but with "self-rotation" added - this introduces *more* chaos which somewhat non-intuitively actually increases the chances of strange attractors !!
