Comment on Understanding Quake’s Fast Inverse Square Rootparent

Comments

How long is it before you can dupe something? A while back, I tried to submit a cool little list of bit hacks, only to find out that the exact same thing had been submitted years ago.

I guess many people probably know about it, but it's a pretty nice list of low level bit hacks:

http://graphics.stanford.edu/~seander/bithacks.html

Not a dupe:

The other thread's url: betterexplained.com/articles/understanding-quakes-fast-inverse-square-root/

This's url: betterexplained.com/articles/understanding-quakes-fast-inverse-square-root

One character as difference: the final slash.

Good catch!

I guess no one can submit that list of bit hacks ever again, unless the dupe-catcher is changed or someone figures out a way to access it from an alternate URL (the site says we're not free to mirror it, even if we're free to use the hacks).

Maybe it'd still be seen as a dupe, but you could try http://graphics.stanford.edu/~seander/bithacks.html?dupe=1
