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.
addChild method enforces these restrictions automatically, and will
remove the new child from previous parents where needed. This behavior
may change in future major releases of the library.
Removes a Node from the Scene.
Makes a copy of this property, with the same resources (by reference) as the original.
Dispatches an event on the GraphNode, and on the associated
Graph. Event types on the graph are prefixed,
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 an ExtensionProperty attached to this Property, if any.
Attaches the given ExtensionProperty to this Property. For a given extension, only one ExtensionProperty may be attached to any one Property at a time.
Lists all ExtensionProperty instances attached to this Property.
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.
Updates the Extras object, containing application-specific data for this Property. Extras should be an Object, not a primitive value, for best portability.
Returns true if the node has been permanently removed from the graph.
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.
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.
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)
