The name of this entity.
Optional hook called when a new point tile is loaded. The parameter is a Points object.
const cloud = new PotreePointCloud(source);
cloud.onPointsCreated = function(pnts) {
// Do something with the points.
}
OptionalrootOptionalsupportsOptionaltableReadonlytypeThe name of the type of this object.
ReadonlyuserAn object that can be used to store custom data about the Entity.
Gets or sets the clipping planes set on this entity. Default is null (no clipping planes).
Note: custom entities must ensure that the materials and shaders used do support the clipping plane feature of three.js. Refer to the three.js documentation for more information.
Gets or sets the frozen status of this entity. A frozen entity is still visible but will not be updated automatically.
Useful for debugging purposes.
Returns the number of layers currently in this object.
Gets whether this entity is currently loading data.
Returns the root object of this entity.
Gets or sets the opacity of this entity.
Gets the current loading progress (between 0 and 1).
Note: This property is only meaningful if loading is true.
Determine if this entity is ready to use.
Gets or sets the render order of this entity.
Gets or sets the visibility of this entity. A non-visible entity will not be automatically updated.
Adds a listener to an event type.
The type of event to listen to.
The function that gets called when the event is fired.
ProtectedassignAssigns the render order of this object.
This may be overriden to perform custom logic.
Fire an event type.
The event that gets fired.
Disposes this entity and all resources associated with it.
The default implementation of this method does nothing. You should implement it in your custom entities to handle any special logic of disposal.
For example: disposing materials, geometries, stopping HTTP requests, etc.
Filters what objects need to be updated, based on updatedSources.
The returned objects are then passed to preUpdate and postUpdate.
Inherited classes should override shouldFullUpdate and shouldUpdate if they need to change this behavior.
Sources that triggered an update
Set of objects to update
Applies the callback to each layer in the object.
Returns a new array containing the layers in this object. Optionally, the predicate can be used to filter out unwanted layers.
// Get all layers from the object.
const allLayers = obj.getLayers();
// Get all color layers from the object.
const colorLayers = obj.getLayers((layer) => layer.isColorLayer);
Optionalpredicate: ((arg0: Layer<LayerEvents, LayerUserData>) => boolean)Returns an approximation of the memory used by this object, in bytes.
Checks if listener is added to an event type.
The type of event to listen to.
The function that gets called when the event is fired.
ProtectedisProtectednotifyProtectedonApplies entity-level setup on a new object.
Note: this method should be called from the subclassed entity to notify the parent class that a new 3D object has just been created, so that it can be setup with entity-wide parameters.
The object to prepare.

Method called after Entity.update.

Asynchronously preprocess the entity. This method may be overriden to perform any operation that must be done before the entity can be used in the scene, such as fetching metadata about a dataset, etc.
A promise that resolves when the entity is ready to be used.
This method is called just before update() to filter and select
which elements should be actually updated. For example, in the
case of complex entities made of a hierarchy of elements, the entire
hierarchy may not need to be updated.
Use this method to optimize the update step by reducing the number of elements to process.
Note: if this functions returns nothing, update() will not be called.
the update context.
the objects that triggered an update step. This is useful to filter out unnecessary updates if no sources are relevant to this entity. For example, if one of the sources is a camera that moved during the previous frame, any entity that depends on the camera's field of view should be updated.
the elements to update during update().
Removes a listener from an event type.
The type of the listener that gets removed.
The listener function that gets removed.
ProtectedsetupApplies entity-level setup on new object's material.
Subclasses can override this to setup custom logic, for instance if the entity can produce objects that are naturally transparent.
the material of the newly created object
This method is called before update to check if the MainLoop
should try to update this entity or not. For better performances,
it should return false if the entity has no impact on the
rendering (e.g. the element is not visible).
The inherited child can completely ignore this value if it makes sense.
true if should check for update
This method is called at the beginning of the update step to determine
if we should do a full render of the object. This should be the case if, for
instance, the source is the camera.
You can override this depending on your needs. The inherited child should
not ignore this value, it should do a boolean OR, e.g.:
return super.shouldFullUpdate(updateSource) || this.contains(updateSource);
Source of change
true if requires a full update of this object
This method is called at the beginning of the update step to determine
if we should re-render updateSource.
Not used when shouldFullUpdate returns true.
You can override this depending on your needs. The inherited child should
not ignore this value, it should do a boolean OR, e.g.:
return super.shouldUpdate(updateSource) || this.contains(updateSource);
Source of change
true if requires an update of updateSource
Traverses all objects in the hierarchy of this entity.

Performs an update on an element of the entity.
Note: this method will be called for each element returned by preUpdate().
