With ReciprocalX,Y,Z functions you can get very awesome variations on IFS formulas, the only problem was that the DE was a lot inaccurate! Particularly in the Navi, the fractal never showed up correctly.
More, the only rotations allowed were multiple of 90°, to keep discontinuities horizontal / vertical...
I solved this annoying problem with reciprocalX3, Y3, Z3 - three new functions! Try them and you will be very surprised.
Even rotations are possible without annoying random cut-planes!
A must try imo. Needless to say; reciprocalX3 is completely different from reciprocalX2 ... There is no way to "convert" them too bad. You must study new parameters!
