Problem
there's slight problem: points $$\scriptstyle a, b$$ lie on $$\scriptstyle XY$$ plane…! points marked as $$\scriptstyle a, b$$ on animation are in fact $$\scriptstyle \mathrm r(a), \mathrm r(b).$$ hope that correcting this won't be much problem for author! :) nameless 14:35, 24 august 2o12 (UTC) what i wrote above is also wrong: points $$\scriptstyle a, b$$ show themselves in the very end (on the line, after rectification of the curve) – this might seem to be little bit more problematic but i'm counting on author as for accuracy! ^_^ nameless 14:42, 24 august 2o12 (UTC) p.s. i hope i haven't made any more mistakes!


 * You're right, technically, they should be best left in the plane. It's how I was originally going for it. However, that posed some technical and visual issues. First of all, I render the scalar field using a point cloud, and this wasn't playing very nicely with it, as the z-sorting of points kept messing up. I'd have to add the points using some fancier method that would be too tricky to be worth implementing in my current animation code.


 * While the points in the surface may be slightly wrong, I don't believe it's incredibly misleading, as they're only being used to represent the endpoints of the curve and integral. The context wouldn't allow for a huge misconception of their meaning, I think, as they should only mean "start" and "end" points. So we should be in the clear. (At least I hope so!)


 * Either way, it wouldn't be very easy to fix right now, unfortunately. But I'll add to my to-do list to address it someday. &mdash; Kieff | Talk 08:34, 4 October 2012 (UTC)

 * Yes check.svg Done. I used "November 2013" rather than "December 2013" though, as this is what the portal page says. — Mr. Stradivarius  ♪ talk ♪ 21:49, 12 November 2013 (UTC)
