Sam Hocevar	6faf4ee067	base: roll our own constants because it’s always a pain in the ass to get M_PI from the platform headers and cast it to float.	12 years ago
Sam Hocevar	d6634da83f	build: fix the WTFPL site URL in all code comments.	12 years ago
Sam Hocevar	28728814cc	core: replace usage of sin() or std::sin() with lol::sin() where appropriate.	12 years ago
Sam Hocevar	56e4332597	build: reorganise math files in a single "math" directory, and get rid of the "shader" source directory since we have "gpu".	13 years ago
Sam Hocevar	0303a8384f	win32: fix Visual Studio compilation and link issues.	13 years ago
Sam Hocevar	14a3e1f739	core: fix a bug on the PS3 version of lol_sin().	13 years ago
Sam Hocevar	b3e2429b9e	core: avoid returning to memory when giving GCC floating point hints.	13 years ago
Sam Hocevar	320e70d8c4	core: a few compilation fixes for non-GCC compilers.	13 years ago
Sam Hocevar	5feadd8b6a	core: fix PS3 compilation; the lol_fdiv implementation was missing.	13 years ago
Sam Hocevar	bf164def53	core: fix an accuracy error in the cos() part of lol_sincos().	13 years ago
Sam Hocevar	2489233a44	core: improve tan() accuracy by tweaking higher order Taylor coefficients.	13 years ago
Sam Hocevar	82d81256b9	core: implement accelerated lol_sincos() and lol_tan().	13 years ago
Sam Hocevar	5be195a8b0	core: slightly reorganise Taylor series in sin() and cos().	13 years ago
Sam Hocevar	49f9c59ff3	core: implement accelerated cos().	13 years ago
Sam Hocevar	a65c472ffd	core: add a code shortcut for sin() on platforms that have cheap branches.	13 years ago
Sam Hocevar	824551e4af	optim: split the Taylor series calculation into two separate values. This is at the cost of one additional multiply, but performance increases by more than 11%, because the PS3 pipeline is a lot happier now.	13 years ago
Sam Hocevar	de496b15fe	core: remove one multiplication and one selection from the optimised version of sinf().	13 years ago
Sam Hocevar	42b22f1163	core: minor optimisation in the x86 version of lol_sin() Instead of dividing by 2 and rounding with magic number 2^52, we round with magic number 2^53, which gives us the parity with at least one mul less.	13 years ago
Sam Hocevar	1b33a7fcb7	core: start implementing optimised trigonometry functions for PS3 and x86.	13 years ago
