Cool Code - Quake 3 Fast InvSqrt() - Particl Digital

Ever play Quake while growing up? Aside from the game itself, the code written to build it is home to a small piece of history in being able to get around the very expensive inverse square root function using very accurate, very fast approximation. The code, specifically how the mythical constant(0x5f3759df) was derived is still…
