Stage B



http://www.fractalforums.com/index.php?action=gallery;sa=view;id=15251

Mandelbox, lights, camera, action!

Using Roquen's domain map for coloring. http://www.fractalforums.com/fragmentarium/fractal-plus-change-of-domain-mashup/

Code:
#group Coloring
// Roquen's domain mash up 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;
}
like this...
Code:
if (i<ColorIterations) orbitTrap = min(orbitTrap, abs(vec4(domainMap(-z),r*r)));
Logged

Resistance is fertile...
You will be illuminated!
