Panolens.js

Javascript Panorama Viewer

Panolens.js is an event-driven and WebGL based panorama viewer. Lightweight and flexible. It's built on top of Three.JS.

Usage

Include three.min.js and panolens.min.js If you want to support offline experience, please include panolens-offline.min.js instead

<script src="js/three.min.js"></script>
<script src="js/panolens.min.js"></script>

This code creates a 360 image panorama. The first panorama added to the viewer will be the entry point. To link panoramas, simply use panorama.link( other_panorama, new THREE.Vector3( X, Y, Z ) ) to connect the two. See examples and documentation for more details.

<script>

	var panorama, viewer;

	panorama = new PANOLENS.ImagePanorama( 'asset/equirectangular.jpg' );

	viewer = new PANOLENS.Viewer();
	viewer.add( panorama );

</script>

PANOLENS.Viewer Configuration

All attributes are optional

<script>
	viewer = new PANOLENS.Viewer({
		container: document.body,		// A DOM Element container
		controlBar: true, 			// Vsibility of bottom control bar
		controlButtons: [],			// Buttons array in the control bar. Default to ['fullscreen', 'setting', 'video']
		autoHideControlBar: false,		// Auto hide control bar
		autoHideInfospot: true,			// Auto hide infospots
		horizontalView: false,			// Allow only horizontal camera control
		cameraFov: 60,				// Camera field of view in degree
		reverseDragging: false,			// Reverse orbit control direction
		enableReticle: false,			// Enable reticle for mouseless interaction
		dwellTime: 1500,			// Dwell time for reticle selection in millisecond
		autoReticleSelect: true,		// Auto select a clickable target after dwellTime
		viewIndicator: false,			// Adds an angle view indicator in upper left corner
