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. — Kieff | Talk 08:34, 4 October 2012 (UTC)

Can you add:

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)
