Link on github pages is wrong #3

Hi: Thanks for these beautiful illustrations.

The link on github pages is wrong, I assume it should jump to this source code repository, not the gallery page itself?

ryanmaguire commented 3 years ago

Hello,

Sorry, it's been a while since I've worked on this. Currently working on a vector graphics library in C so I can continue with this project.

Could you clarify what you're asking?

I mean, the button above does not lead to the source code: https://ryanmaguire.github.io/asymptote/

ryanmaguire commented 3 years ago

Ohhh! Thank you for bringing that to my attention. I have been greatly reorganizing this repo and trying to clean up the asymptote code and tikz code. I'll fix that once the reorganization is complete.

Thanks!

BTW, if you are interested in drawing hyperbolic/euclidean figures, maybe you can have a look at my project here:

https://github.com/neozhaoliang/pywonderland/blob/master/src/uniform-tilings

Also the way you draw fractals in python can be made much faster.

Hi again,

Sorry for the delayed response, I need to learn to check the issues section more often. I am actually trying to algorithmically produce hyperbolic tilings. Specifically the (8,3) tiling to represent embeddings of graphs on genus 2 surfaces. Unfortunately the link you left gave me a 404 error.

In my email there was a question about my C library that seems to have disappeared. It does not (unfortunately) support latex embeddings, but does support 3D drawings. 2D images are rendered as SVG, which I could not for the life of me figure out how to embed LaTeX into.

The reason I started it was to draw very large random walks on 2D manifolds. Particularly a random walk with 500,000 steps on a torus. Asymptote unfortunately crashes if you try to draw that many elements. Here's the preliminary code to make such a figure. https://github.com/ryanmaguire/libtmpl/blob/master/extras/random_walk/tmpl_random_walk_on_a_torus_to_svg.c

Oh my mistake. The code for that project has been moved to the released code here: https://github.com/neozhaoliang/pywonderland/releases/tag/0.1.0

The documentation is online:
https://pywonderland.com/uniform-tilings/

I understand making svg/eps figures contain lots of elements can result in very large file, not suitable for embedding into pdf. Better to convert to png. Asymptote may has a limit on the size of its output buffer? I don't know ...

The (8, 3) tiling produced by the program I mentioned above:

8-2-3

I'm also planning more projects on hyperbolic space visualizations, after I finished some euclidean tiling programs at hand.
