three.js Getting started with three.js Simple Boilerplate : spinning cube and orbit controls with damping
Example
This is the basic HTML file that can be used as a boilerplate when starting a project. This boilerplate uses orbit controls with damping (camera that can move around an object with deceleration effect) and creates a spinning cube.
