3Demos is Drew Youngren's 3D Calculus Visualizations. Developed by Drew Youngren and the Columbia University Center for Teaching and Learning.
This project comprises of two main parts:
- Django back-end.
Django Channels server for mathplayground. Structure based on:
https://channels.readthedocs.io/en/latest/tutorial/index.html All
Django code is in the
mathplayground/directory. - Front-end using Svelte and
three.js. The main JavaScript code can be
found in
media/src/.
Install Redis and start the redis service.
redis-server
Start django server:
make runserver
In order to get the django daphne application responding to WebSockets, you will need to set up a proxy with nginx to forward and set certain headers. See: https://channels.readthedocs.io/en/latest/deploying.html#nginx-supervisor-ubuntu
To make changes to the svelte application in media/src/, first install the
node dependencies with npm install. Then you can run the rollup build via
npm like this:
npm run dev
Or, make a one-time production build of the applcation with npm run build.
Both of these commands will update the compiled JS at media/mathplayground/build/.
