Relnotes: yes Replace the cosine table with a sine table, which (due to the vagaries of 2016-01-02T16:40:37Z Dag-Erling Smørgrav des@FreeBSD.org 2016-01-02T16:40:37Z urn:sha1:23e6278ed92673fff55edef271bfa26729040b95 rounding) has better spread. Implement fp16_sin() to go along with fp16_cos(). In the rendering loop, switch from addition to subtraction so the center of the pattern will be a trough rather than a peak. This is completely arbitrary, of course, but looks better to me. 17 years and change after I wrote warp_saver, here's a simple plasma effect 2016-01-01T04:04:40Z Dag-Erling Smørgrav des@FreeBSD.org 2016-01-01T04:04:40Z urn:sha1:a50b01d224ab38985b9d47fe2e27a4ae546fc62b (currently only three circular patterns) which requires quite a bit of fixed-point arithmetic, including sqrt() and cos(). Happy New Year!
