FWIW, here is a crude animated GPU-based tour of Julia set around
the main cardioid of the Mandelbrot set. This is implemented in
a pixel shader that has real time color cycling, animation and
point-and-click zooming capabilities. I am planning to extend
this out into a full blown online fractal explorer, complete with
a custom function parser. I am wondering if it works for you?

So far, I can get it to work in Chrome and Firefox. IE does not
seem to want to render; I am probably doing something slightly
wrong in the shader, but it does work in these other browsers.
Perhaps IE does not like the fact that I am breaking out of a for
loop. IIRC, the shader language does not like breaking out of a
loop early; Humm...

Anyway, here is a link to the online program:

http://webpages.charter.net/appcore/fractal/webglx/ct_complex_field.html

This is using an escape method I came up with that actually
generates an entire infinite vector field, complete with field lines.
Last time I saw an algorithm for field lines in a complex escape time
fractal, the method was just way too complex; mine is almost too easy!

FWIW, it is fairly similar to some of my simulated 2d gravitational field
line animation's on YouTube:

I think I found a unique method to generate a vector field that totally
comprises everything out of the main set; so to speak.

Well, does it work for you?



Thanks!



BTW, I am using 32-bit floats, so the distance you can zoom to before rapid
pixilation will be rather limited!

Sorry about that for I have not emulated 64-bit floats with 32-bit base
floats yet, but it is on the list!

:^)
