The Julia set has a close relation to the Mandelbrot set. The Mandelbrot set is the set of complex numbers to which there are continuous Julia sets. The morph is created in real-time by changing the constant value in the complex iteration procedure thus creating different Julia sets.
Everything is done in real-time so run this applet on a reasonably fast computer. I wrote it on a 733 MHz where I got approx 50 fps, but it still runs with a decent frame rate on lesser CPUs. You can also show the fps count.
Gaston Julia was a French mathematician who studied the Julia set during the twenties. His work was not given attention until the development of computer graphics which could actually visualize the set.
Benoit B Mandelbrot was among the first to develop computer programs to print fractals and is largely responsible for the contemporary interest in fractals worldwide.
I wrote this code in November 2000. I made a similar program back in 1994 using assembly language on a 16 MHz Motorola 68000 CPU, which actually felt faster than this one, which would suggest that assembler running on 16 MHz is more efficient than Java running on 733 MHz. (I know, there are several other factors as well, but I kind of like the idea…)
