Here is the documentation page for configuring colorings (made for Eduard a
while back):

http://www.gravitation3d.com/magictile/info/identifications.html

I'll be the first to admit that creating new colorings is not the easiest
thing. I'm happy to answer questions though, or to discuss how it might be
improved.

Melinda,

I've solved some of puzzles a couple of months ago, but there was nothing
new for me - just versions of tetrahedron and cube. For something new we
should try new coloring (with 12,24,36 colors etc.). Unfortunately I don't
understand Roice's notation of puzzle definition, and can't add good
puzzles to MT.

Hi Andrey,

Sorry for the delay. I was camping this weekend and disconnected from the
interwebs.

To find working values, I looked at your file and compared your coloring
configuration to the one for the hemidodecahedron. Two tags needed to be
changed:

- "UseMirroredEdgeSet" needed to be set to false. That is true by
default, but I've noticed it generally must be false for non-orientable
puzzles.
- The hemidodec also had "EndRotation" = 1.

Here is a working file, which only differs from your file by those two tags:

http://www.gravitation3d.com/magictile/4d_cubing/%7B10,3%7D%206C%20edited.xml

I wanted to note that there was one required alteration to the
hemidodecahedron coloring config. The elliptic puzzle had "InitialEdgeSet"
= 1, but for the hyperbolic puzzle, this needed be left as the default
(initial reflections across all edges) so it could fill out the whole
plane. It is so interesting how the spherical puzzles can be expanded to
hyperbolic tilings.

Hope this helps!

Roice

Yes, thanks Andrey! I will add these to the standard MagicTile
distribution in the next few days. I'm going to configure some additional
slicings on them first so we can have a bunch of puzzles to play on these
new colorings (luckily, those are much easier to setup than finding working
colorings).

I didn't follow your question "So starting edge for "EndRotation" is
unpredictable?". The EndRotation is applied to the tile after all the
reflections have been done, and it affects all edges equally. The number
here doesn't signify an edge index. It specifies a rotation angle (the
entered value multiplied by 2=F0/p). If this doesn't clarify, can you
describe more what you are asking?

Cheers,
Roice

Yes, thanks Andrey! =C2=A0I will add these to the standard=
MagicTile distribution in the next few days. =C2=A0I'm going to config=

I didn'=

fter all the reflections have been done, and it affects all edges equally. =
=C2=A0The number here doesn't signify an edge index. =C2=A0It specifies=

Great work, Andrey!

It looks to me like your 18-color puzzle is non-orientable (not
"non-oriented") just like your 6-color puzzle. Readers should=
be
aware that it's extremely easy to add puzzles like these into MT.
Just drop the XML files into the "MagicTile\config\user" fold=
er.

Hi Roice,

of spherical and hemispherical puzzles and one (18 colors) looks

Hi Andrey,



Sorry for the delay. =C2=A0I was camping this weekend and

To find working values, I looked at your file and
compared your coloring configuration to the one for the
hemidodecahedron. =C2=A0Two tags needed to be changed:


  • "UseMirroredEdgeSet" needed to be set to fa=
    lse.
    =C2=A0That is true by default, but I've noticed it
    generally must be false for non-orientable puzzles.
    =C2=A0

  • The hemidodec also had "EndRotation" =3D 1.=


Here is a working file, which only differs from your
file by those two tags:











I wanted to note that there was one required
alteration to the hemidodecahedron coloring config. =C2=A0T=
he
elliptic puzzle had "InitialEdgeSet" =3D 1, but f=
or the
hyperbolic puzzle, this needed be left as the default
(initial reflections across all edges) so it could fill
out the whole plane. =C2=A0It is so interesting how the
spherical puzzles can be expanded to hyperbolic tilings.
=C2=A0




Hope this helps!

Sweet, thanks for the 36C! I will add that one to the MT distribution as
well. (Please feel free to keep them coming if you find more :D)

You are right that EndRotation does return us back to the white-green edge,
and I edited your picture to help clarify what MagicTile is doing.

http://groups.yahoo.com/neo/groups/4D_Cubing/photos/albums/622194858/lightb=
ox/2117008453

No rotations happen until the one at the very end. It is only performing
reflections across the edges until then. So the portion on the white tile
near A gets reflected to B, then C, then D. And from D, we just need one
integer turn CCW to get to the final position, which is why EndRotation is
1. (By the way, the reflection edge indices and the EndRotation are always
interpreted in a CCW sense on the tiling, regardless of whether we are on a
mirrored face or not.)

It could have been better to implement it the way you thought it was
working, because it can be difficult to figure out what EndRotation is
needed. It's hard to track what orientation the white tile is in after a
set of reflections. I've often played "guess and check" with EndRotation,
which has served me well at times because it produced unexpected colorings
I would have never considered possible.

seeya,
Roice

We start from white face, go to green, make 2 turns CCW, go to yellow, m=
ake 3 turns CCW, return to white. What should we do next? I thought that En=
dRotation should return us back to white-green edge (where we started - in =
this case it should be 2. Or may be 8, because we are on the mirrored face =

Great work, Andrey!

It looks to me like your 18-color puzzle is non-orientable (not
"non-oriented") just like your 6-color puzzle. Readers should=
be
aware that it's extremely easy to add puzzles like these into MT.
Just drop the XML files into the "MagicTile\config\user" fold=

Hi Andrey,



Sorry for the delay. =A0I was camping this weekend and
disconnected from the interwebs.




To find working values, I looked at your file and
compared your coloring configuration to the one for the
hemidodecahedron. =A0Two tags needed to be changed:


  • "UseMirroredEdgeSet" needed to be set to fa=
    lse.
    =A0That is true by default, but I've noticed it
    generally must be false for non-orientable puzzles.
    =A0

  • The hemidodec also had "EndRotation" =3D 1.=


Here is a working file, which only differs from your
file by those two tags:












I wanted to note that there was one required
alteration to the hemidodecahedron coloring config. =A0The
elliptic puzzle had "InitialEdgeSet" =3D 1, but f=
or the
hyperbolic puzzle, this needed be left as the default
(initial reflections across all edges) so it could fill
out the whole plane. =A0It is so interesting how the
spherical puzzles can be expanded to hyperbolic tilings.
=A0




Hope this helps!

As for EndRotation: look at this picture: href=3D"https://www.dropbox.com/s/zyjhd5o88na810t/Screenshot%202013-10-28%=

We start from white face, go to green, make 2 turns CCW, go to yellow, m=
ake 3 turns CCW, return to white. What should we do next? I thought that En=
dRotation should return us back to white-green edge (where we started - in =

Great work, Andrey!

It looks to me like your 18-color puzzle is non-orientable (not
"non-oriented") just like your 6-color puzzle. Readers should=
be
aware that it's extremely easy to add puzzles like these into MT.
Just drop the XML files into the "MagicTile\config\user" fold=

Hi Andrey,



Sorry for the delay. =A0I was camping this weekend and
disconnected from the interwebs.




To find working values, I looked at your file and
compared your coloring configuration to the one for the
hemidodecahedron. =A0Two tags needed to be changed:


  • "UseMirroredEdgeSet" needed to be set to fa=
    lse.
    =A0That is true by default, but I've noticed it
    generally must be false for non-orientable puzzles.
    =A0

  • The hemidodec also had "EndRotation" =3D 1.=


Here is a working file, which only differs from your
file by those two tags:













I wanted to note that there was one required
alteration to the hemidodecahedron coloring config. =A0The
elliptic puzzle had "InitialEdgeSet" =3D 1, but f=
or the
hyperbolic puzzle, this needed be left as the default
(initial reflections across all edges) so it could fill
out the whole plane. =A0It is so interesting how the
spherical puzzles can be expanded to hyperbolic tilings.
=A0




Hope this helps!

Sweet, thank you! I will work on getting slicings setup for these and
adding them (hopefully this weekend). We'll probably have over 750 puzzles
after this set, making Ed's life more difficult if he wants to stay at the
mark of solving half of all MagicTile puzzles :)

Any of the colorings you particularly like? Or any unusual ones?

On the {12,4} 40C, can you try upping NumTiles to a much higher value and
see if it helps? (for example, even 15000 or more) Since the dodecagons
are pretty large and there are many colors, the fundamental region will be
big. My guess is that some of the identifications are long enough that
they go beyond the initially generated tiling. That's just a guess, but it
is a problem I've encountered in the past. MagicTile will only recurse to
a certain level regardless, and so this one may still not be possible. If
you'd like to send me your working file, I can experiment with it some too.

Cheers,
Roice

You are right that EndRotation does return us back to the wh=

No rotations happen until the one at the very end. =A0I=
t is only performing reflections across the edges until then. =A0So the por=

h is why EndRotation is 1. =A0(By the way, the reflection edge indices and =
the EndRotation are always interpreted in a CCW sense on the tiling, regard=

It could have been better to implement it the way you t=

is in after a set of reflections. =A0I've often played "guess and=

Great work, Andrey!

It looks to me like your 18-color puzzle is non-orientable (not
"non-oriented") just like your 6-color puzzle. Readers should=
be
aware that it's extremely easy to add puzzles like these into MT.
Just drop the XML files into the "MagicTile\config\user" fold=

Hi Andrey,



Sorry for the delay. =A0I was camping this weekend and

To find working values, I looked at your file and
compared your coloring configuration to the one for the
hemidodecahedron. =A0Two tags needed to be changed:


  • "UseMirroredEdgeSet" needed to be set to fa=

    =A0That is true by default, but I've noticed it

    =A0

  • The hemidodec also had "EndRotation" =3D 1.=


Here is a working file, which only differs from your
file by those two tags:














I wanted to note that there was one required
alteration to the hemidodecahedron coloring config. =A0The
elliptic puzzle had "InitialEdgeSet" =3D 1, but f=
or the
hyperbolic puzzle, this needed be left as the default
(initial reflections across all edges) so it could fill

spherical puzzles can be expanded to hyperbolic tilings.

Hope this helps!

Hi Andrey,

I looked at your {12,4} 40C puzzle using the debugger yesterday, and the
issue is with MagicTile, not your configuration. I expect the {15,3} 48C
will not work yet either.

The problem is that the code currently culls tiles whose center lie within
.00001 of the disk boundary. On the {12,4}, where tiles shrink very fast
with each reflection, this limits the total number of tiles generated to
about 5k, regardless of the 'NumTiles' setting. If I reduce the cutoff
threshold, MagicTile generates more tiles and the identifications work.

Anyway, I could make a code change to allow overriding that culling
threshold, which we could set on these puzzles with larger polygons and
lots of colors. (I wouldn't want to change the cutoff for existing
puzzles, for fear of unintended effects.) Maybe there is a better solution
too, but that's what I'm thinking at the moment.

Roice

Hi Andrey,

I looked at your {12,4} 40C =
puzzle using the debugger yesterday, and the issue is with MagicTile, not y=
our configuration. =A0I expect the {15,3} 48C will not work yet either.v>


The problem is that the code currently culls tiles whose cen=
ter lie within .00001 of the disk boundary. =A0On the {12,4}, where tiles s=
hrink very fast with each reflection, this limits the total number of tiles=
generated to about 5k, regardless of the 'NumTiles' setting. =A0If=
I reduce the cutoff threshold, MagicTile generates more tiles and the iden=
tifications work.



Anyway, I could make a code change to allow overriding =
that culling threshold, which we could set on these puzzles with larger pol=
ygons and lots of colors. =A0(I wouldn't want to change the cutoff for =
existing puzzles, for fear of unintended effects.) =A0Maybe there is a bett=
er solution too, but that's what I'm thinking at the moment.

Roice,

Here is=A0my version of {12,4} 40 colors: w" href=3D"https://www.dropbox.com/s/gmums460yu713q5/%7B12%2C4%7D%2040C.zip=

=A0. Actually, it's just a combination of 8C=A0(octahedron=
) and 5C (asymmetric {4,4} carpet). So combined puzzle should be asymmetric=
, and =A0that's why I don't use Mirrored Edge Set.



My estimation is that I've added about a half of possible 4-reflecti=
on identities. What I don't understand is why I don't see white col=
ors in=A0some cells where it should=A0be mapped by these=A0reflections (lik=
e 3:3:3) - most of them are just black. I've tried to raise number of t=
iles up to 20000, but it doesn't help.




=A0 The only non-trivial coloring of {12,3} is 24 colors - co=
mbination of cube and tetrahedron. Others are just versions of well-known s=
pherical (or hemispherical) puzzles :)

Any of the colorings you particularly like? =A0Or any unusua=

On the {12,4} 40C, can you try upping NumTil=

You are right that EndRotation does return us back to the wh=

doing. =A0




No rotations happen until the one at the very end. =A0I=
t is only performing reflections across the edges until then. =A0So the por=
tion on the white tile near A gets reflected to B, then C, then D. =A0And f=
rom D, we just need one integer turn CCW to get to the final position, whic=
h is why EndRotation is 1. =A0(By the way, the reflection edge indices and =
the EndRotation are always interpreted in a CCW sense on the tiling, regard=
less of whether we are on a mirrored face or not.)






It could have been better to implement it the way you t=
hought it was working, because it can be difficult to figure out what EndRo=
tation is needed. =A0It's hard to track what orientation the white tile=
is in after a set of reflections. =A0I've often played "guess and=

Great work, Andrey!

It looks to me like your 18-color puzzle is non-orientable (not
"non-oriented") just like your 6-color puzzle. Readers should=
be
aware that it's extremely easy to add puzzles like these into MT.
Just drop the XML files into the "MagicTile\config\user" fold=

Hi Andrey,



Sorry for the delay. =A0I was camping this weekend and
disconnected from the interwebs.




To find working values, I looked at your file and
compared your coloring configuration to the one for the
hemidodecahedron. =A0Two tags needed to be changed:


  • "UseMirroredEdgeSet" needed to be set to fa=
    lse.
    =A0That is true by default, but I've noticed it
    generally must be false for non-orientable puzzles.
    =A0

  • The hemidodec also had "EndRotation" =3D 1.=


Here is a working file, which only differs from your
file by those two tags:
















I wanted to note that there was one required
alteration to the hemidodecahedron coloring config. =A0The
elliptic puzzle had "InitialEdgeSet" =3D 1, but f=
or the
hyperbolic puzzle, this needed be left as the default
(initial reflections across all edges) so it could fill
out the whole plane. =A0It is so interesting how the
spherical puzzles can be expanded to hyperbolic tilings.
=A0




Hope this helps!
