Features for Fewest Moves - NISS

[andersonaap]

Would be wonderful can use roofpig
to visualize FMC reconstruction.

Enable a kind of token - like (switch) or (inverse) and (normal)
that would would show a cube after applying a NISS (switch).

scramble: D2 U2 L' R2 B2 F2 U2 B U2 L D' F2 U B U B' D
solution
L2 F2 // 2x2x2
U' B U2 // pseudo 2x2x3
(switch)
U2 B U // 2x2x3 + EO
(switch)
B' R' B2 // Pseudo F2L
(switch)
B' L' F D2 F' L B2 // AB3C

We could visualize this kind of reconstruction in.

L2 F2 U' B U2 (switch) U2 B U (switch) B' R' B2 (switch) B' L' F D2 F' L B2

This is really interesting. Visualizing NISS solutions is an unsolved problem, AFAIK, and makes the sport very hard to follow.

Let me look into some ideas for a few days!

This isn't quite what you asked for, but I made a NISS solution visualizing web page that I hope can be a good start.

It's at http://birdflu.lar5.com/fmc and you can enter a NISS format solution and an (optional) scramble, and get an animation of each step.

A few premade solutions I grabbed from http://fmcsolves.cubing.net/?tag=niss:

That really nice good start. Great job.

Do you intend to add the Nissualizer page in roofpig repository or create another one?

[larspetrus]

What's missing for it to be useful?

I'm working on a database of all LL algs (http://birdflu.lar5.com/), and that code isn't public yet. I put the Nissualizer there, since it's easy.

@larspetrus
Sugestions:

• put solution in a textarea. each line will be a step displayed in roofpig.
• let white on top, green on front or offer a option for choosing orientation

what about ?
https://run.plnkr.co/plunks/r1WWZt/ (edit)

maybe in showing normal/inversed pair of cubes before each step.
or just a one cube that step was done.
