# `class` Scene

Scene is the main keeper of a scene and scene graph in simplygon. The scene is self-contained, with materials, textures, etc. to describe a full scene.

# Properties

Property	Description
Name	The name of the Scene object. (Inherited from Object)

# Methods

Method	Description
AddCustomField	Adds a custom data array field. To be able to add a field, it must have a name that does not conflict with the existing custom fields.
AddObserver	Adds a user-defined observer object to the interface, that will receive events from the interface. (Inherited from Object)
Append	Appends another scene to this scene. All materials, textures etc.
CalculateExtents	Calculates the axis-aligned bounding box of the whole scene. If the node tree contains no geometric data, or all data is hidden, the bounding box is not calculated, and the method returns false.
CalculateExtentsOfSelectionSet	Calculate extents of all nodes in a specified selection set.
CalculateExtentsOfSelectionSetId	Calculate extents of all nodes in a specified selection set. The selection set must reside in the selection set table, at the specified id.
CalculateExtentsOfSelectionSetName	Calculate extents of all nodes in a specified selection set. The selection set must reside in the selection set table, named the specific name.
Clear	Clears the whole scene and releases all items in the graph.
Compact	Will remove mesh nodes that consist of empty geometry. The node transformation will be added to all child transformations. If the root node is a sceneMesh with empty geometry, it will be replaced with a generic sceneNode having the same transformation.
CreateAABB	Returns a scene containing the axis aligned bounding boxes of either the entire scene or per mesh in the scene.
DeepCopy	Deep copies the source scene, and all things assigned to it, including all nodes, geometry data, materials and tables.
