Detailed Description

Backgrounds are 3D environments that can be reflected on the 3D objects surfaces (like a sky). The background is also used for refractive objects. The background can be considered as texture mapped on an infinite sphere.

There are two interfaces to access a component: The shell interface (ISh. or I3DSh.) and the external interface (IEx. or I3DEx.) . You can get one from the other using QueryInterface.

Whenever it is possible you should use the Shell interface to access the component because the Shell will make sure that the parameter map of the external component is valid. This is especially important if the component is animated. For more information on components see the Overview of the SDK.
