Hi, I'm doing a svg style implementation. arcing. check out the document, seems some words not so right:) 1, sweep flag: I checkout wiki, there is no "positive-angle" speaking. as programmer, I can get, it just step or delta value >0. but other users maybe get it better, if other common word used, f.e, counter(anti)-clockwise, or left(right) handle law. IMO, even "ccw" better than sweep. 2, implnote F.6.5, step4, eval the included angle, the acos result range from 0-PI, but document stats: where θ1 is fixed in the range −360° < Δθ < 360° Indeed, it misguide me. Though not use math thing long years, I get back ever feeling at math by bad reviewing the lessons, and send this message. BTW I hope my english speaking got. If have some problem, I can send message again with more syntaxed thing. Regards Qinxian
