it was a great time but no longer maintainable by c.Kleinhuis contact him for any data retrieval,
thanks and see you perhaps in 10 years again

Hi everyone, just wanted to introduce myself.

In the last few years I've been exploring fractal flames in JWildfire (thanks Andreas!), and contributing new "variations" to the codebase. (Err, actually I now have quite a backlog of stuff I need to commit...). Most recently I've been focused on finding new ways to apply inversive geometry to IFS fractals.

Lately I've been thinking about applying similar ideas to escape-time fractals. I had browsed FractalForums before, but in the last few months I've really dug in. Particularly into the _huge_ number of threads/posts regarding development of the Mandelbox and its relatives/descendants. Truly an invaluable resource!

I've started coding up some ideas as GLSL fragments for Fragmentarium. And ready to post about those ideas. But thought my first forum post should be an introduction. Thanks everyone for contributing to this amazing forum!

CozyG

Welcome CozyG smiley
This is something I use to turn things inside out wink http://www.fractalforums.com/fragmentarium/fractal-plus-change-of-domain-mashup/

Code:
uniform bool Invert; checkbox[false]
// coordinate to invert to infinity
uniform vec3 InvertC; slider[(-5,-5,-5),(0,0,0),(5,5,5)]
// performs the active c = T(s)
vec3 domainMap(vec3 c)
{
float s = dot(c,c);
return c/s + InvertC;
}

...
then before the iteration loop where z = incoming position ...
Code:
if(Invert) z = domainMap(-z);

a number of the latest series of images I posted here in the Fragmentarium gallery use this in 2D and a few 3D animations
