<h1>[name]</h1>
<p class="desc">A class for generating a two-dimensional ring geometry.</p>
<iframe id="scene" src="scenes/geometry-browser.html#RingGeometry"></iframe>
<script>
// iOS iframe auto-resize workaround
if ( /(iPad|iPhone|iPod)/g.test( navigator.userAgent ) ) {
var scene = document.getElementById( 'scene' );
scene.style.width = getComputedStyle( scene ).width;

}
</script>
<h2>Example</h2>
<code>var geometry = new THREE.RingGeometry( 1, 5, 32 );
var material = new THREE.MeshBasicMaterial( { color: 0xffff00, side: THREE.DoubleSide } );
var mesh = new THREE.Mesh( geometry, material );
scene.add( mesh );
</code>
<h2>Constructor</h2>
<h3>[name]([param:Float innerRadius], [param:Float outerRadius], [param:Integer thetaSegments], [param:Integer phiSegments], [param:Float thetaStart], [param:Float thetaLength])</h3>
<p>
innerRadius — Default is 0.5. <br />
outerRadius — Default is 1. <br />
thetaSegments — Number of segments. A higher number means the ring will be more round. Minimum is 3. Default is 8. <br />
phiSegments — Minimum is 1. Default is 8.<br />
thetaStart — Starting angle. Default is 0. <br />
thetaLength — Central angle. Default is Math.PI * 2.
</p>
<h2>Properties</h2>
<p>See the base [page:Geometry] class for common properties.</p>
<h3>[property:Object parameters]</h3>
<p>
An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
</p>
