Description

Uscene, Uscene2D and Uscene3D define the basic components required for displaying a 2D or 3D graphics window:

Top - the display parent of all objects displayed in the scene

Top2D (Uscene only) the display parent for the 2D objects in the scene

Lights - the number of lights, light transformations and light attributes for each light.

Camera - the default camera and camera attributes in the scene

Camera2D (Uscene only) the 2D camera for the scene

View - view attributes, pick information, display output, and display window user interface

The objects with the U prefix contain a built-in user interface defined by the AVS/Express UI kit. The objects with the M prefix do not have any user interface.

Scene // - collection of components for a window
Top // - object's display parent
Top2D // - (Uscene only) 2D objs display parent
Lights // - light information for window
Camera // - camera information for window
Camera2D // - (Uscene only) 2D camera for window
View // - View, colormap, picking, output and
// __window display for view

Input Ports

Top.child_objs

The list of input objects to be rendered in the scene.
