Detailed Description

Billboard objects are two dimensional images that have a position in 3D space.

The first two components of the object's scaling property define the X and Y dimensions. The Z scaling is ignored. The orientation is also ignored: billboard objects always face the viewer, and are always "right side up". The metaobject type for billboard objects is "object3D.billboard". Position and scaling properties are as in the "object3D" type, and a "material" property (containing a texture image or solid color) is added.

You should create new Billboard objects using MetaFactory. After creation, you must call setPropertyAccessControl() on the new object, as well as setPosition(), setScaling() (even though the Z scaling factory is ignored, you should supply a value), and setOrientation() (even though the orientation is irrelevant) -- Object3D requires values for all of these properties to work.
