flatmush	5dd63f37ce	Updated sin lut to use ~200KiB for it's table with the same accuracy, the lookup table implementation tends to run at about 33-36% of the speed of sinf on my machine (Intel T5500). Fixed a bug in the sin lut code so that the results are always accurate. Changed fixsingen tool to generate tables correctly for the new implementation.	2011-02-25 16:07:39 +00:00
flatmush	0317f964f4	Added option to replace sin function with ~384KiB look-up table for fastest and most accurate results. Added tool to generate sin tables. Tests indicate that using a lut is still ~2.1% out from sinf so it's very possible that our sin function is more accurate than the libmath sinf function on the computer I'm testing with. In which case the accuracy results are offset by that amount.	2011-02-25 15:32:23 +00:00
