The Mudbox scene is organized as a tree of objects that derive from the TreeNode object. The primary scene elements involved in the visual representation of the scene derive from GroupNode. These are:

• Camera - Represents a camera (point of view) in a Mudbox scene. Only one is active at one time.
• Geometry - Represents a 3d object in the scene.
• Light - Represents a light source in the scene. Derives from GroupNode.
• Transformation - Represents a position, scale, and/or rotation transform of a child node such as a Camera, Geometry or Light.

You retrieve a pointer to the scene via a call to Kernel::Scene(), on the singleton Kernel object. For example: Kernel()->Scene().
