Methods

  • Adds a listener to an event type.

    Type Parameters

    Parameters

    • type: T

      The type of event to listen to.

    • listener: EventListener<(Entity3DEventMap & EntityEventMap)[T], T, Tiles3D<TMaterial, UserData>>

      The function that gets called when the event is fired.

    Returns void

  • Type Parameters

    • T extends string

    Parameters

    • type: T
    • listener: EventListener<{}, T, Tiles3D<TMaterial, UserData>>

    Returns void

  • Parameters

    Returns Promise<void>

  • Parameters

    • n: Tile
    • depth: number = 0

    Returns void

  • Test whether this entity contains the given object.

    The object may be a component of the entity, or a 3D object.

    Parameters

    • obj: unknown

      The object to test.

    Returns boolean

    true if the entity contains the object.

  • 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.

    Returns void

  • Parameters

    • metadata: ProcessedTile
    • Optional requester: Tile

    Returns Promise<Tile>

  • 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.

    Parameters

    • updateSources: Set<unknown>

      Sources that triggered an update

    Returns Set<unknown>

    Set of objects to update

  • Applies the callback to each layer in the object.

    Parameters

    Returns void

  • Returns an approximated bounding box of this entity in the scene.

    Returns Box3

    the resulting bounding box, or null if it could not be computed.

  • 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);

    Parameters

    Returns Layer<LayerEvents, LayerUserData>[]

  • Attached layers expect to receive the visual representation of a layer (= THREE object with a material). So if a layer's update function don't process this kind of object, the layer must provide a getObjectToUpdateForAttachedLayers function that returns the correct object to update for attached layer from the objects returned by preUpdate.

    Parameters

    • meta: Tile

      the Mesh or the object containing a Mesh. These are the objects returned by preUpdate or update.

    Returns ObjectToUpdate

    an object passed to the update function of attached layers.

  • Checks if listener is added to an event type.

    Type Parameters

    Parameters

    • type: T

      The type of event to listen to.

    • listener: EventListener<(Entity3DEventMap & EntityEventMap)[T], T, Tiles3D<TMaterial, UserData>>

      The function that gets called when the event is fired.

    Returns boolean

  • Type Parameters

    • T extends string

    Parameters

    • type: T
    • listener: EventListener<{}, T, Tiles3D<TMaterial, UserData>>

    Returns boolean

  • Returns true if this object belongs to this entity.

    Parameters

    • obj: unknown

      The object to test.

    Returns boolean

  • Parameters

    • node: Tile

    Returns void

  • Applies 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.

    Parameters

    • obj: Object3D<Object3DEventMap>

      The object to prepare.

    Returns void

    Example

    // In the subclass
    const obj = new Object3D();

    // Notify the parent class
    this.onObjectCreated(obj);
  • Picks objects from this entity.

    Implementations must respect at least limit and filter options.

    Parameters

    • coordinates: Vector2

      Coordinates on the rendering canvas

    • Optional options: PickOptions

      Options

    Returns Tiles3DPickResult[]

    Target

  • Method called after update.

    Parameters

    • context: Context

      the update context.

    • changeSources: Set<unknown>

      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.

    Returns void

  • 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.

    Returns Tile[]

    the elements to update during 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.

    Returns Promise<void>

    A promise that resolves when the entity is ready to be used.

  • Removes a listener from an event type.

    Type Parameters

    Parameters

    • type: T

      The type of the listener that gets removed.

    • listener: EventListener<(Entity3DEventMap & EntityEventMap)[T], T, Tiles3D<TMaterial, UserData>>

      The listener function that gets removed.

    Returns void

  • Type Parameters

    • T extends string

    Parameters

    • type: T
    • listener: EventListener<{}, T, Tiles3D<TMaterial, UserData>>

    Returns void

  • Parameters

    • metadata: ProcessedTile
    • Optional parent: Tile
    • _redraw: boolean = false

    Returns Promise<Tile>

  • 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.

    Returns boolean

    true if should check for update

  • Parameters

    • node: Tile

      The tile to evaluate;

    Returns boolean

    true if the request can continue, false if it must be cancelled.

  • 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);

    Parameters

    • updateSource: unknown

      Source of change

    Returns boolean

    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);

    Parameters

    • updateSource: unknown

      Source of change

    Returns boolean

    true if requires an update of updateSource

  • Parameters

    Returns void
