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

hrmm... Yes it is difficult to find such function.  head batting
Thank you for the explanations. I'll rename my scripts to "non-mandalay" and "pseudo-mandalaybox".  grin

cheesy
Well, x,y,z are orthogonal axis...
Fractal formulas modify axis values normally.
All goes fine as long as axis stay ortho... But if they become a linear combination of other ones something goes wrong wink
Because fractal becomes stretched in some direction.
See my older fractal; http://www.fractalforums.com/index.php?action=gallery;sa=view;id=17143

It had infinitely stretched squares, it was wrong. In fact they appeared ALL the times, with ALL julia seeds... sad
Because I assigned wrongly max(x,y) to z, and similar things... That caused sometimes axis to become equal!

I guess that happens when you do;
   vec3 p1=p;
   p.x=DBFold(p1,fo.x,g.x,w.x);
   p.y=DBFold(p1.yzx,fo.y,g.y,w.y);
   p.z=DBFold(p1.zxy,fo.z,g.z,w.z);
   return p;

So, in some regions of 3d space, x becomes a sum of y and z... Or equal to z (or to y)
Because after a dbfold you should update two axis value not just one
smiley

I can only make a guess seeing your image and I can't really be sure.
Because I (too) tried to catch the perfect formula without success.
Seems complicated really. And the kifs works really like a charm and has infinite detail cheesy
Plus, never seen a single cut... And it is very fast.
So... I guess I'll keep it even if the fold isn't like I intended. wink

So it is not a mandalay?  embarrass I'll have to verify the formulas.
What do you mean by parallel axis?
Anyway, I still like the extrusion effect. tongue stuck out

Thanks for the efforts you are putting A Beer Cup
I very appreciate.
I see some zones lose fractal detail
Are you sure axis aren't parallel in those zone? smiley If they are parallel, it's an unwanted feature more than an effect smiley
Don't want to be rude - if so sorry embarrass
