At times, don't you just need a simple camera which rotates around an object in Theee.js?

OrbitControls.js

/*
 * @author @blurspline https://github.com/zz85
 * Similar to a turntable or a hovering camera?
 */
THREE.OrbitControls = function( camera, target, distance, height, time ) {

	var rotationUnits = time * 1000;
	var startTime;
	
	this.start = function() {
		this.startTime = Date.now();
	}
	
	this.update = function() {
		
		var lapsed = Date.now() - this.startTime;
		var angle =  (lapsed % rotationUnits) / rotationUnits * Math.PI * 2;
		
		camera.position.x = Math.sin(angle) * distance + target.x;
		camera.position.z = Math.cos(angle) * distance + target.z;
		camera.position.y = height + target.z;
		camera.lookAt(target);
	}
	
};
