Detailed Description

This nodekit is used to organize camera, (SoCameraKit), light, (SoLightKit), and object, (SoShapeKit, SoSeparatorKit, and SoWrapperKit) nodekits into a scene. A scene is composed of a list of cameras, a list of lights, and a list of children. There are three parts created by this nodekit: cameraList, lightList, and childList.

The cameraList part is a list part of SoCameraKit nodes. The list itself is an SoNodeKitListPart, and since only one camera can be active at a time, the container of the list part is an SoSwitch node. Use setCameraNumber(), and the scene kit will set the switch to make that camera active.

The lightList part is a list of SoLightKit nodes. The lightList is used to illuminate the objects contained in the childList part.

The childList part contains a set of SoSeparatorKit nodes. You can add any kind of SoSeparatorKit to this list, including SoShapeKit and SoWrapperKit. Since each SoSeparatorKit in turn contains a childList, this part is used to describe a hierarchical scene. (See the reference page for SoSeparatorKit). All members of childList are lit by the lights in lightList and rendered by the active camera in cameraList.

Parts

cameraList
This part is an SoNodeKitListPart It has a container that is an SoSwitch node. The list may contain only SoCameraKit nodekits. The active child of the SoSwitch is the active camera. This part is NULL by default, but is automatically created whenever you add a camera, as with setPart("cameraList[0]", myNewCamera) .

lightList
This part is an SoNodeKitListPart that uses an defines an SoGroup as its container The list may contain only SoLightKit nodekits. Add SoLightKits to this list and they will light the members of the childList of this SoSceneKit. This part is NULL by default, but is automatically created when you add a light.

childList
This part is an SoNodeKitListPart that uses an SoGroup for its container. The list may contain only SoSeparatorKit nodekits or nodekits derived from SoSeparatorKit (e.g., SoShapeKit and SoWrapperKit). These children represent the objects in the scene. This part is NULL by default, but is automatically created whenever you add a child to the childList. Also, when asked to build a member of the childList, the scenekit will build an SoShapeKit by default. So if the childList part is NULL, and you call: getPart("childList[0]", TRUE) . the scene kit will create the childList and add an SoShapeKit as the new element in the list.
