## Overview

ThreejsFun is a small collection of independent browser-based Three.js graphics examples, not one integrated application. The user-facing workflow is to open an example and view its rendered scene; the sampled scripts show scene setup, animation, interaction, and rendering within each example. The tree also identifies plane- and sphere-animation examples, but their implementations were not sampled, so their internal behavior and connections are left unspecified.

Main entry points: [`SimpleScene/main.js`](https://github.com/prmondal/threejsfun/blob/master/SimpleScene/main.js) (Simple Scene), [`Instancing/main.js`](https://github.com/prmondal/threejsfun/blob/master/Instancing/main.js) (Instancing Demo), [`TexturedCube/main.js`](https://github.com/prmondal/threejsfun/blob/master/TexturedCube/main.js) (Textured Cube), [`SimpleShader/main.js`](https://github.com/prmondal/threejsfun/blob/master/SimpleShader/main.js) (Custom Shader)
