Magic Cube

Standarize the 'isSolved()' method: now all objects, except one (Dino4) have a standard isSolved().
This incidentally also fixes detection of the solved state in case of Diamond4, i.e. a Master FTO.

Come back to creating the objects from mesh.

Add flag of Madagascar.

Make the 3x3 and 4x4 Diamond meshes smaller.

Finally remove cubit creation from the implementation classes and move it to the TwistyObject.

Convert the last object, Skewb Ultimate, to the new scheme.

Convert the two Squares to the new scheme.

Convert Skewb to the new scheme. New smaller mesh for the Master Skewb.

Convert Rex Cube to the new scheme.

Convert Redi Cube to the new scheme.

Convert Pyraminx to the new scheme. Make Pyra4 and Pyra5 meshes much smaller.

Convert Megaminx to the new scheme.

New, smaller Master Kilominx mesh.

Move 1) Jing 2) Kilominx to the new cubit creation scheme.
Make the Master Kilominx mesh a bit smaller.

Move 1) Helicopter 2) Ivy to the new cubit creation scheme.

Move 1) bandaged 3x3 2) normals cubes 3) octahedrons 4) both dinos to the new cubit creation scheme.

Important step towards making the implementation of an individual puzzle code-free (i.e. data-only): move the 'MeshBase[] mMeshes' variable from the individual classes to the parent TwistyObject.

Make the Kilominx cubit creation a bit more standard.

Introduce ObjectShape - a class encapsulating a shape of a Cubit.
Make the Megaminx cubit creation a bit more standard.

Minor.

COnvert the last object, the Rex cube, to the new cubit creation scheme. Provide the new Rex mesh.

New Ivy mesh.

Convert the Ivy corner cubit to the new, 'universal' cubit creation method.

This forces deep changes to 'createRoundSolid' and the underlying 'MeshPolygon' class to make them support arbitrary Polygon 'centers of face convexity'.

Reason: the faces of this cubit are concave and such default 'center of face convexity' (which by default used to be (0,0)) turned to lie outside the face - which produces strange visual artifacts.

Corrections for the Bandaged cubit creation.

Convert bandaged Cubes to the standard mesh creation code.
