Uviewer, Uviewer2D, Uviewer3D

The Uviewer components define all of the necessary components for the display portion of a graphics application. This consists of a default graphics window that displays the default list of objects (defined by the Scene.Top.child_objs input port) and a collection of user interface editors that the user can use to control the display of these objects.An application should only have a single Uviewer but you can add additional graphics windows to the Uviewer either using the view editor panel found in the Editors->View->Create page or by directly adding Uscene and Uview objects to the Uviewer using the Network Editor.Each Uviewer contains a Scene, a Scene_Selector, and a Scene_Editor. The Scene defines a top-level object (Top), a Camera that defines a viewport onto those objects, and a View window to display those objects in (see Uscene for more information). The Scene_Selector allows the user to select a current Scene for editing purposes (see GDview_selector for more information). The Scene_Editor defines the interactors that allow mouse interaction with the object, toolbar icons such as reset, normalize and center, and a set of editor panels that are installed into the Editors menu panel of an application (see Uscene_editor for more information)The Uviewer modules only differ in the type of Scene that they define. The Uviewer2D component uses a Uscene2D, the Uviewer3D uses a Uscene3D and the Uviewer uses a Uscene. The Uscene2D is like a Uscene3D but has the camera type set to 2D and may have a different default renderer. The Uscene2D and Uscene3D have a single Top object and a single Camera. The Uscene displays 2D and 3D objects in the same window. It has two Top objects: Top for 3D objects and Top2D for 2D objects and two Cameras, Camera for 3D objects and Camera2D for 2D objects.

Input Ports

One or more objects to be rendered. For Uviewer and Uviewer3D, these objects are renderered in 3D. For Uviewer2D these objects are rendered in 2D.

One or more objects to be rendered in 2D. These objects are rendered on top of the 3D objects connected to Scene.Top.child_objs

Output Port

Outputs a connection to the currently selected view. This will change as you click in each view window to point to the selected view. If you want to connect to a particular view, export a port for the object: Uviewer.Scene.View.View and connect to that.

This is a connection to the current object. This is the object that the object editors are using. In the default configuration, this is the same as the picked_obj below.

This is a connection to the object most recently selected by the user through the pick operation. This operation is initiated in the Uviewer component with the <ctrl>-left mouse button.
