I hand-drawn a strange function that I thought could be cool for experimenting with mutations of ABox.
The modification effect is neaty and deserves more deep looking.
Let me show you how it works, just a little tricky formula that adds a fold that will trigger after the normal folding limit to work like an abs() - so the result is something that stays on borderline between Amazing Surf and the old Box!
// Mixed fold by Luca 2016.
// do this for all 3d axis, or 4d axis if you have a 4d abox
// Tglad normal fold is cfg->x = fabs(cfg->x + fold) - fabs(cfg->x - fold) - cfg->x;
sg = sign(cfg->x);
folder = sg * cfg->x- fold; // fold is Tglad's
folder += fabs(folder);
folder = min(folder, foldModX); // and Y,Z,W
cfg->x -= sg*folder;
Conversely if foldMod tends to infinity, you get Tglad's fold. I found that 2000 can be enough.
If foldMod = 2*fold, you get the perfect Mixed Folding, simulating abs() and fold at the same time.
If foldMod = 4*fold, you get a double folding just like doing fold twice.Images on next post.
