[name] can be used to create a decal mesh that serves different kinds of purposes e.g. adding unique details to models, performing dynamic visual environmental changes or covering seams.
[example:webgl_decals decals ]
var geometry =  new THREE.DecalGeometry( mesh, position, orientation, size );
		var material = new THREE.MeshBasicMaterial( { color: 0x00ff00 } );
		var mesh = new THREE.Mesh( geometry, material );
		scene.add( mesh );
		
		
		mesh — Any mesh object.
		position — Position of the decal projector.
		orientation — Orientation of the decal projector.
		size — Size of the decal projector.
