		<h1>[name]</h1>

		<p class="desc">
			A sprite is a plane that always faces towards the camera, generally with a
			partially transparent texture applied.<br /><br />

			Sprites do not cast shadows, setting <code>castShadow = true</code> will
			have no effect.
		</p>

		<h2>Code Example</h2>

		<code>
		const map = new THREE.TextureLoader().load( 'sprite.png' );
		const material = new THREE.SpriteMaterial( { map: map } );

		const sprite = new THREE.Sprite( material );
		scene.add( sprite );
		</code>

		<h2>Constructor</h2>

		<h3>[name]( [param:Material material] )</h3>
		<p>
			[page:Material material] - (optional) an instance of
			[page:SpriteMaterial]. Default is a white [page:SpriteMaterial].<br /><br />

			Creates a new [name].
		</p>

		<h2>Properties</h2>
		<p>See the base [page:Object3D] class for common properties.</p>

		<h3>[property:Boolean isSprite]</h3>
		<p>Read-only flag to check if a given object is of type [name].</p>

		<h3>[property:SpriteMaterial material]</h3>
		<p>
			An instance of [page:SpriteMaterial], defining the object's appearance.
			Default is a white [page:SpriteMaterial].
		</p>

		<h3>[property:Vector2 center]</h3>
		<p>
			The sprite's anchor point, and the point around which the sprite rotates.
			A value of (0.5, 0.5) corresponds to the midpoint of the sprite. A value
			of (0, 0) corresponds to the lower left corner of the sprite. The default
			is (0.5, 0.5).
		</p>

		<h2>Methods</h2>
		<p>See the base [page:Object3D] class for common methods.</p>

		<h3>[method:this copy]( [param:Sprite sprite] )</h3>
		<p>Copies the properties of the passed sprite to this one.</p>

		<h3>
			[method:undefined raycast]( [param:Raycaster raycaster], [param:Array intersects] )
		</h3>
		<p>
			Get intersections between a casted ray and this sprite.
			[page:Raycaster.intersectObject]() will call this method. The raycaster
			must be initialized by calling [page:Raycaster.setFromCamera]() before
			raycasting against sprites.
