Scenes represent a set of visual objects to render.
Typically a glTF file contains only a single scene, although more are allowed and useful in some cases. No particular meaning is associated with additional scenes, except as defined by the application. Scenes reference Nodes, and a single node cannot be a member of more than one scene.
Adds a Node to the scene.
Makes a copy of this property, with the same resources (by reference) as the original.
Copies all data from another property to this one. Child properties are copied by reference, unless a 'resolve' function is given to override that.
Removes both inbound references to and outbound references from this object. At the end of the process the object holds no references, and nothing holds references to it. A disposed object is not reusable.
Returns true if two properties are deeply equivalent, recursively comparing the attributes of the properties. Optionally, a 'skip' set may be included, specifying attributes whose values should not be considered in the comparison.
Example: Two Primitives are equivalent if they have accessors and materials with equivalent content — but not necessarily the same specific accessors and materials.
Returns default attributes for the property. Empty lists and maps should be initialized
to empty arrays and objects. Always invoke
super.getDefaults() and extend the result.
Returns a reference to the Extras object, containing application-specific data for this Property. Extras should be an Object, not a primitive value, for best portability.
Returns the name of this property. While names are not required to be unique, this is encouraged, and non-unique names will be overwritten in some tools. For custom data about a property, prefer to use Extras.
Returns true if the node has been permanently removed from the graph.
Lists all root Nodes in the scene.
Lists all ExtensionProperty instances attached to this Property.
Returns a list of all properties that hold a reference to this property. For example, a material may hold references to various textures, but a texture does not hold references to the materials that use it.
It is often necessary to filter the results for a particular type: some resources, like Accessors, may be referenced by different types of properties. Most properties include the Root as a parent, which is usually not of interest.
const materials = texture .listParents() .filter((p) => p instanceof Material)
Removes a Node from the scene.
Updates the Extras object, containing application-specific data for this Property. Extras should be an Object, not a primitive value, for best portability.
Sets the name of this property. While names are not required to be unique, this is encouraged, and non-unique names will be overwritten in some tools. For custom data about a property, prefer to use Extras.
Visits each Node in the scene, including descendants, top-down.
