If your engine doesn't need to render objects outside the viewport, then you don't need to generate those objects until you actually need to render it.
n Number of factors
2 2 (1, 2)
2x3 4 (1, 2, 3, 6)
2x3x5 8
2x3x5x7 16
(2x3x5x...x500499th prime)x2
2^500499 + 2^500498 factors.
(2x3x5x...x500499th prime) x (2 x 2)
2^500499 + 2^500498 + 2^500498 = 2^500500 factors.
