Re: [NTG-context] animation using \startuseMPgraphic
Dear Wolfgang,
I’d like to ask you one more.
To make an animation, almost same graphics are drawn repeatedly.
In my code, for example,
The base figure(two circles, line, boundingbox) is fixed and only points are
moved.
But it draws the base figure every time and it is not inefficient.
Is there a way to draw the base figure once, and draw the points only at each
frame?
Thank you.

Sounds good. Is documentation part of (3) or can it be another section? It's part of (1) as it is now but of course we can have an additional one (5) for extra documentation. While I want to install "everything" on my work machine, it would make sense to restrict a server installation (or a beta version for tests) to the bare minimum (without docs, but maybe with fonts). Nowadays even 'everything' is not that much is it? not compared to the whole of tex live. There was a time that a tex installation was considered large but nowadays many single task programs come with a larger installation. I also would very much appreciate to be able to install older versions (like "in the old times") to check when some changes happened. Git repositories serve the same purpose, probably even better. I’d suggest to keep those sections in separate repositories and install them as texmf-context, texmf-fonts, texmf-docs or the like (similar to the current state, but selectable). Git submodules *should* work to combine several repos, but the implementation has flaws (e.g. "git submodule update" tries to access all submodules at once, and if you must enter credentials, the prompts get mixed up). Basically we're talking (1) texmf-context(tex, mp, lua sources, documentation, luametatex code) (2) texmf- (luametatex and luatex bin) (3) texmf(mostly fonts as it is now) (4) texmf-modules(from the garden) and if you want (5) texmf-docs but context documentation goes into texmf-context. We're not going top be too clever ... these systems come and go (as do some 'standards') so any installation model should be simple kind of 'copy/fetch something' (with no dependencies on anything we don't have in the repository either, apart from a compiler is one wants to compile luametatex for some platform we don't provide). Keep in mind that for specific usage demands are too different so all we can do is provide what there is. Also keep in mind that too much split also makes for tricky dependencies, for instance binaries are the latest so when you want an older context - something that you can do now too when you use the existing github repository - you have to make sure you have the right binary. This is why (1) will have the engine source code: integrity (don't worry the source code compresses to < 2 meg and uncompressed is less that some of these large fonts). Anyway, once we have it we can always make clever installers. Actually when you want to go real small it's easier to just install and wipe what you don't need.

to create a layer for it.

We have to adapt installers too and we want to do it right from the start. Now, we're not in a particular hurry, but in playing with all this it can happen that the current distributions get flaws. (As a side effect the more or less official release of luametatex has been postponed a few times because it depends on (1) which in turn depends on pushing older context distributions etc. But then, due to the current health crisis, time has slowed down anyway.)

Thank you for introducing yourself! It's indeed so, as you pointed out, a lot of information about ConTeXt is a bit outdated. But, as every programmer knows, it's hard after finishing a program to find the time to document it. And ConTeXt is developing quickly. For the same reason as you I left LaTeX four or five years ago and began to use ConTeXt. And peu à peu I changed even all my elder LaTeX-programs to ConTeXt. If you have trouble to find a solution to a problem ask the list. There are very friendly and highly experienced people and you certainly will be astonished how quick you shall get an answer in most cases. But always send a so called MWE (Minimal Working Example) along with your question. Good luck with ConTeXt and give it more than just a try!

Re: [NTG-context] animation using \startuseMPgraphic
Jeong Dal schrieb am 19.04.2020 um 07:08:
Dear all,
I am trying to make an animation using the animation module.
But it draws 10 figures instead of creating animation.
Is there anything I have to do more?
You have to put each animation step in a frame environment. I recommend
also to set the boundingbox to the same size for each frame, otherwise
your graphic jumps around.
When you use \recurselevel you have to use this:
\startanimation[menu=yes]
\dorecurse{10}
{\startexpanded
\startframe
\useMPgraphic{inversionPoint}{n=\recurselevel}%
\stopframe
\stopexpanded}
\stopanimation
or use #1 to access the counter level and get rid of \startexpanded:
\startanimation[menu=yes]
\dorecurse{10}
{\startframe
\useMPgraphic{inversionPoint}{n=#1}%
\stopframe}
\stopanimation
