@mclarekin You really make my poor brain creek on this morning:} Thank you for that!
Please pardon me, as I do not understand all yet (but I think I get the general idea), so much to learn so little time;)
First the zwizzle thing: It is an existing term! Really thought maybe Luca had it made up, such a wonderful word
I was presuming we'd (well ok, you and Luca, and Crist-JRoger, (still way too intimidating yet for me
)) get the 4d-rotation properly going some day, then w will be playing along nicely, won't it?
The usefulness rotation between two abs()-formulas in a loop I get, I hope I will remember!
Then the reciprocal: I have already last night added another transform (_invcylindrical) into the mix (a very popular combination in mb3d, gives nice 'rooms', though in Fragm the lighting inside objects (not the proper fractalish 'inside' but outside surfaces inside the fractal is a drama
Placing the two transforms before the loop will let them behave like pre-transforms. To be proper transforms the need to be placed within the loop, I always thought?
a scaled inverse squared plus offset
Of the whole thing? Or one of the numbers.. or whatever I want?
Just for fun I have already changed things within the code of the line, as you say: anything goes, and it is really behaving quite nicely when altered a bit here and there.
BTW had the thumbs-up from Luca, it's a proper reciprocalX3b
