coordinate generator

index.js

      var points = [];
      var x = y = z = this.constraint;
      var constraintDecrement = this.constraint * -1;

      for (var x = this.constraint; x >= constraintDecrement; x--) {
        points.push({
          'pos': {'x' : x, 'y' : y, 'z' : z}
        });
        for (var y = this.constraint; y > constraintDecrement; y--) {
          points.push({
            'pos': {'x' : x, 'y' : y, 'z' : z}
          });
          for (var z = this.constraint; z > constraintDecrement; z--) {
            points.push({
              'pos': {'x' : x, 'y' : y, 'z' : z}
            });
          };
        };
      };

Article here is saying that do/while loops are much faster, especially with the condition at the end so I may try that.

Humm, if my CS education is coming back to me OK, the snippet above runs on the order of O(n^3), 8n^3 to exact, where n is this.contraint. So for:

this.constraint = 10 ==> 8,000 array entries
this.constraint = 100 ==> 8,000,000 array entries

That's a lot. Even if you could speed it up, the 8,000,000 entries in the array might be too huge?

Yup, it's way too huge, 10 will have to suffice for now, lol.
