Group: a3dl.

Extends: a3dl:object3D.MATERIALINFO

This object type is used for including rectangular 2D images in a 3D world. The 'position' property defines the 3D position of the image. The first two components of the 'scaling' property (X and Y) define the size of the 2D image. The Z component of 'scaling' is ignored. The 'orientation' property is ignored. The 2D image should always face the viewpoint/camera. The material properties are used to provide the image (as a texture) or solid color of the billboard.
