[NTG-context] MetaPost Animations
I've created several animations using MetaPost/ConTeXt, and I have also created a webpage with these animations. The URL to the page is http://www.tlhiv.org/animations/ Feedback is appreciated, and if there is a particular animation that you would like to see included, let me know and I will attempt to code them up in MetaPost, provide the source code, and include them on the webpage.

Re: [NTG-context] MetaPost Animations
Dear Troy, I just looked up your animations webpage: congratulations for the beautiful work you have done, and thanks for sharing. I played a little bit with the hypocycloid source file you sent some time ago and found it useful for other situations as well. Would it be possible to have the source files of the other examples you show on the webpage http://www.tlhiv.org/animations/ Also, if I may suggest something, an animation like the one for Riemann sums would be very intersting for illustrating the Lebesgue integrals in order to show to students what is going on.

There are some animated gifs at: http://en.wikipedia.org/wiki/B%C3%A9zier_curve such curves are typical for mp so maybe they qualify.

Neat. MP - Flash seems to work well. One thing, which you may know, gear teeth do not normally have rectangular profiles. Nowadays, they are usually involutes of a circle and formerly were usually cycloids (so the gears don't slip against each other when they turn). I don't have a reference, but google turned up http://www.cadquest.com/books/pdf/gears.pdf, which shows how to draw involute gears. Are you using the animations, or some frames perhaps, in a ConTeXt document? I usually use Mathematica for such animations, but it and its ilk are expensive, although there are other alternatives. As I'm still learning MP/Lua/ConTeXt, I'm just interested in the ways others use the system. Thanks for sharing.

Re: [NTG-context] MetaPost Animations
One thing, which you may know, gear teeth do not normally have rectangular profiles. This must be what Hans was talking about. Are you using the animations, or some frames perhaps, in a ConTeXt document? Well, actually I'm using ConTeXt/MetaPost to generate each frame of the animation automagically. The webpage will soon allow for downloading the source for each ConTeXt document. This generates a multi-page PDF where each page of the PDF is a frame of the animation. SWFtools (specifically, pdf2swf) can then be used to convert the PDF to SWF.

Are the gears more correct now?

Re: [NTG-context] MetaPost Animations
Dear Troy, The gears are much better now. However, have a look at http://fr.wikipedia.org/wiki/Fichier:Involute_wheel.gif and http://fr.wikipedia.org/wiki/Engrenage The animation for Gibbs is also very nice: thanks for sharing! I tried the TeX file for your Gibbs phenomena animation: I could not get the same pictures as you show on your webpage. I get only one page out of 8, and the log file says several times: unknown path q ! Improper `clip'. to be read again Best regards: OK On 29 déc. 2012, at 03:55, Troy Henderson thend...@gmail.com wrote: Are the gears more correct now?
