rotate: Perform Rotations, Wide Moves and Middle Slice Moves

Description

Functions for rotating the whole cube and performing middle slice (E M S) and wide (Uw Rw Fw Dw Lw Bw) moves.

Usage

wide(aCube, wmv)
slice(aCube, smv)
rotate(aCube, rot)

Arguments

aCube

A cubieCube object.

smv

A single string giving a middle slice move. Must be one of E E1 E' E1' E2 E2' E3 E3' M M1 M' M1' M2 M2' M3 M3' S S1 S' S1' S2 S2' S3 S3'.

wmv

A single string giving a wide move. Lower case letters and w notation are both allowed. For turns on the U face must be one of Uw u Uw1 u1 Uw' u' Uw1' u1' Uw2 u2 Uw2' u2' Uw3 u3 Uw3' u3', and similarly for the R F D L B faces.

rot

A rotation. This can be specified using an integer or a character string. If an integer, must be a number between 1 and 24 representing one of the 24 possible rotations in space. The number 1 is the no rotation case. If a character string, must be one of 0 x x1 x' x1' x2 x2' x3 x3' y y1 y' y1' y2 y2' y3 y3' z z1 z' z1' z2 z2' z3 z3' where the 0 character string represents no rotation. Character strings correspond only to the 10 distinct rotations around the the x, y and z axes (including the no rotation case).

Value

A cubieCube object.

Details

These functions are used internally by the move function for performing rotations, wide moves and middle slice moves, but can also be called directly if you only need to perform a single move. In most circumstances it is better to use the move function.

The definition of the E M S middle slice moves is respectively given by D'Uy' L'Rx' B'Fz'. In particular, the S slice direction is different to what you may find elsewhere; the definition used for S in this package is consistent with the rotation directions.

Examples

Run this code

# NOT RUN {
aCube <- getCubieCube("HenrysSnake")
bCube <- slice(rotate(aCube, "z'"), "M2") 
cCube <- move(aCube, "z'M2")
identical(bCube, cCube)

# }
# NOT RUN {
plot(cCube)
# }
# NOT RUN {
plot3D(cCube)
