There are many services out there that allow you to display your 3D models through the web, but they usually require a click+load time. Three.js is a customizable way to have a 3D model on the page as simple as a picture.

Right-click pans if using a mouse. If you’re on a mobile device 3-fingers pans. If you’re on a macbook touchpad 2-finger-click pans.
