Hollow and somewhat damaged Menger sponge

u/UEZ

Well done. Looks very nice. Can somebody explain me what this is about: [a,b,z]=x[q]||[0,0,6.3]. I assume it has something to do with arrays... Thx :-)
u/tomxor

It's called destructuring. The right hand side simply evaluates to an array (x[q] or [0,0,6.3] is x[q] is falsey). Then the elements of this array are assigned to variable names based on positions on the left, e.g a=0, b=0, z=6.3. Note that the left hand side is syntactic sugar, it's not an array literal.
u/UEZ

@tomxor: thx for your explanation. :-)
