Three.js Hypotrochoid/Epitrochoid Visualizer

This is a small Typescript project that utilizes the Three.js JavaScript-based library to visualize roulette curves called Epitrochoid and Hypotrochoid curves. These types of curves are especially known because of the Spirograph toy, which draws Hypotrochoid curves.

Dependencies

To be able to compile and run the code locally in the browser, the following things are needed:

• Node.js: A package manager for Node.js packages. Through this package manager all other dependencies can be installed automatically (see how in the next section: Usage). The dependencies that, most importantly, should be installed are the following:
  • Three.js: A library that uses WebGL and provides an API for creating and and displaying animated computer graphics in a web browser.
  • Webpack: A library that is able to bundle all dependencies into static assets, which can then easily be included into a static website.
  • dat.GUI: A lightweight library for changing variables through a graphical user interface.

Usage

Installing all dependencies:

1. Through the terminal clone this repository to a certain directory and navigate to it:

   git clone https://github.com/nicklasxyz/HypotrochoidEpitrochoidVisualizer && \
   cd HypotrochoidEpitrochoidVisualizer 
   

2. Install all dependensies needed for the application to run:

   npm install --force
   

Serving the website locally:

1. Through the terminal, serve the website by running:

   npm run dev
   

2. Finally, navigate to the address through a web browser: http://localhost:8000/web.

Building the website:

1. Through the terminal, simply run:

   npm run build
   

2. The folder named web should now contain all the static assets.
