\"Snapshot<\/p>\n

Above is a snapshot image. \u00a0Here’s the real thing<\/a>.<\/p>\n

It works for any size of cube from 2 x 2 x 2 up to 11 x 11 x 11. \u00a0Actually, 11 is an\u00a0arbitrary\u00a0limit – the same code would work for any size of cube. \u00a0Use the little + and – buttons up in the top left hand corner to select the size of the cube.<\/p>\n

Turning a face or slicing a layer is pretty intuitive – just click somewhere on the cube, hold down the mouse button and drag.<\/p>\n

Turning the whole cube around is the same but you have to double-click, hold the mouse button down on the second click and then drag.<\/p>\n

There’s a bug in the turning of the whole cube which causes the orientation to jump occasionally. \u00a0I think I can fix it by using quaternions<\/a> to do the whole-cube rotation, but with the demise of Flash I’m thinking this would be a good project to migrate to HTML5 – and then I could patch in the quaternion stuff at the same time.<\/p>\n

You can also use the keyboard to turn layers (there’s a sort of agreed way of doing this among speed-cubers, and the simulation mostly uses the agreed keys),<\/p>\n","protected":false},"excerpt":{"rendered":"
