Reanimate is a library for programmatically generating animations with a twist towards mathematics / 2D vector drawings. A lot of inspiration was drawn from 3b1b's manim library.

Reanimate aims at being a batteries-included way of gluing together different technologies: SVG as a universal image format, LaTeX for typesetting, ffmpeg for video encoding, inkscape/imagemagick for rasterization, potrace for vectorization, blender/povray for 3D graphics, and Haskell for scripting.

In more practical terms, reanimate is a library for turning code like this:

main = reanimate $ docEnv $ playThenReverseA drawCircle

... into animations like this:

[Draw Circle](examples/doc_playThenReverseA.hs)

What is reanimate good at?

Vector graphics and math

[Tangent/Normal](examples/demo_tangent.hs) [Fourier](examples/tut_glue_fourier.hs)

Mapping and tracing

[Geo JSON](videos/map-projection/gif.hs) [Object tracing](examples/tut_glue_potrace.hs)

Mathematical typesetting and effects

[LaTeX](examples/tut_glue_latex.hs) [Stars](examples/demo_stars.hs)

2D physics and 3D graphics

[2D Physics](examples/tut_glue_physics.hs) [3D graphics](examples/tut_glue_povray.hs)


Reanimate is built using the Haskell Tool Stack. For installation instructions, see: https://docs.haskellstack.org/en/stable/README/

Optionally, you can install one or more of these programs to enable additional features:

I highly recommend that you install at least 'ffmpeg' and 'latex'.

Installing / Running an example

Reanimate ships with a web-based viewer and automatic code reloading. To get a small demo up and running, clone the repository, run one of the examples (this will install the library), and wait for a browser window to open:

$ git clone https://github.com/Lemmih/reanimate.git
$ cd reanimate/
$ stack build
$ stack ./examples/doc_drawCircle.hs

This should render the doc_drawCircle example in a new browser window. If you then change the animation source code, the browser window will automatically reload and show the updated animation.
