// This set of controls performs orbiting, dollying (zooming), and panning. It maintains
// the "up" direction as +Y, unlike the TrackballControls. Touch on tablet and phones is
// supported.
//
//    Orbit - left mouse / touch: one finger move
//    Zoom - middle mouse, or mousewheel / touch: two finger spread or squish
//    Pan - right mouse, or arrow keys / touch: three finter swipe
//
// This is a drop-in replacement for (most) TrackballControls used in examples.
// That is, include this js file and wherever you see:
//    	controls = new THREE.TrackballControls( camera );
//      controls.target.z = 150;
// Simple substitute "OrbitControls" and the control should work as-is.

Hi,

This is nice.. You should however consider making it a fully fledged GitHub project and not just a Gist (or have you already done that?)

Hi Felix. Is this file under an MIT license? If so, would you mind adding that to the heading?

Hello there,

Where is the mistake in my code?

It does not rotates.

Any chance we can make this commonJS compatible?

Good evening. I'm trying to make a code with OrbitControls.js, when people browses I want to avoid firing the "touchend" event. I'm doing it like in a desktop, checking "touchmove" after "touchstart" and setting a flag to avoid it, however, it does not work, because on line 503, stopPropagation() is called.

What I want to know is why is it called?

Great code!And hope a new version with the Event Listener of the Gyroscope，then we can use it to develop VR-app.
