Lot of truth in this article. We used to use the floating point hack for radix sort[1] in alpha sorting transparent quads on a back to front renderer. Depending on the cache line size we'd either have 3 or 4 pass sort radix with a puny little arm chip. Guess what, that thing screamed because it was linear memory reads all the way through. We could throw thousands of quads at the thing and it wouldn't even flinch. [1] http://stereopsis.com/radix.html http://stereopsis.com/radix.html
