* PQ Torus Knot

** About

[[https://ferano.io/3d-fp/][Live Link]]

This is an attempt to implement the [[https://en.wikipedia.org/wiki/Torus_knot][PQ Torus Knot]] in the Elm programming
language.

** Showcase

** Keybindings

You can increment/decrement P or Q using the keyboard to get different geometry;

- Increment P: ~p~
- Increment Q: ~q~
- Decrement P: ~w~
- Decrement Q: ~o~

** Building with Elm 0.18.0
To install the binaries manually, follow this short guide; - [[https://sirfitz.medium.com/install-elm-0-18-0-in-2021-3f64ce298801][Install Binaries]]

If you want to use =npm= instead; - =npm install -g elm@elm0.18.0=

If you use =npm=, note that you will likely need an older version of Node.js, so
it is recommended to use [[https://github.com/nvm-sh/nvm][nvm]] for that. I have not attempted this method
personally, fyi.

Once you have the Elm compiler, go ahead and run

=elm make Torus.elm=

And that should first pull in all the dependencies then generate an =index.html=
file.

Alternatively, you can use ~elm-reactor~, run the command and open up your browser
to ~https://localhost:8000~ and then click on ~Torus.elm~ in the nice project
webview provided.
