# `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 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.
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.
EvaluateDefaultGlobalTransformation	Evaluates the global transformation of the specified node at a specific time. EvaluateDefaultGlobalTransformation is used to evaluate the default transformation, regardless of node animation.
GetBoneTable	The bone table of the scene.
GetCascadedSceneCount	Get the number of cascaded child scenes.
GetCascadedSceneForIndex	Get the scene for the given cascaded child scene index, which must be less than the number of cascaded child scenes.
GetClass	Get the name of the Scene class. (Inherited from Object)
GetCustomField	Adds/Removes/Gets a custom data field.
GetInf	The inferior (minimum) extent of the scene.
GetMappingImage	The MappingImage object for the scene.
GetMaterialChannels	Get all unique material channel names for all materials used in scene.
GetMaterialChannelsWithTextureInputs	Get all unique material channel names having texture inputs for all materials used in scene.
GetMaterialTable	The material table of the scene.
GetNodeByGUID	Gets a node defined by an id.
GetNodeFromPath	Gets a node defined by a path. Please note that the path must contain names for each level to be able to find the specified node.
GetRadius	The scene radius.
GetRootNode	The root node of the scene.
GetSelectionSetTable	The selection set table of the scene.
GetSubNodeByGUID	Gets a node defined by an id from the specified node tree.
GetSup	The superior (maximum) extent of the scene.
GetTextureTable	The texture table of the scene.
GetTriangleCount	Traverses the scene meshes in the scene and returns the total triangle count.
HasCustomField	Checks if a custom field is present in the scene.
IsA	Returns true if Scene is a or is a descendant of the class named as the type parameter. (Inherited from Object)
IsNull	Returns true if the Scene object is invalid. (Inherited from Object)
IsSameObjectAs	Returns true if the Scene object is valid. (Inherited from Object)
LoadFromFile	Loads a scene from file.
NewCombinedGeometry	Combines all the geometries from the scene and returns a copy.
NewCombinedGeometryFromSelectionSet	Combines all the geometries from the selection set and returns a copy. If the selection set ID is -1, then all the geometries will be copied.
NewCopy	Creates a new deep copy of the scene, and all things assigned to it, including all nodes, geometry data, materials and tables.
NonNull	Returns true if the Scene object is valid. (Inherited from Object)
PrintInfo	Prints the content/info of the Scene object to the log. (Inherited from Object)
RemoveCustomField	Removes a custom data field.
RemoveObserver	Removes a previously added observer object. (Inherited from Object)
RemoveSceneNodes	Removes all scene nodes.
RemoveSceneNodesInSelectionSet	Removes all scene nodes listed in a selection set.
RemoveSceneNodesOfType	Removes all scene nodes of a specific type.
RemoveUnlinkedBones	Removes all bones in the scene that are not linked by any SceneMesh geometry data. Note that the removal only removes leaf nodes in the scene.
SaveToFile	Saves a scene to file.
SelectNodes	Selects all nodes of the type specified in the parameter and returns the selection set ID. If no types were found, it returns -1.
StandardizeMaterials	Clears all previous data in both the material and texture tables and creates new, empty materials for every material id referenced by the MaterialIds field in the scenes geometrydata objects. Useful for cleaning up scenes containing invalid material references and making them exportable when you are primarily interested in the geometry and not the materials.
