Small optimization to Minecraft demo: not drawing bottom faces.

For this extended Cube primitive with "sides" parameter.

You can use it to switch off cube faces like this:

    var cube = new Cube( 100, 100, 100, 1, 1, materials, false, { ny: false } );

Default is all six faces on => { px: true, nx: true, py: true, ny: true, pz: true, nz: true }
