Constructors

Properties

clrBackground: Color = ...
mtxPivot: Matrix4x4 = ...
baseClass: typeof Component = Component

refers back to this class from any subclass e.g. in order to find compatible other resources

iSubclass: number = ...

subclasses get a iSubclass number for identification

subclasses: typeof Component[] = []

list of all the subclasses derived from this class, if they registered properly

Accessors

  • get isSingleton(): boolean
  • Is true, when only one instance of the component class can be attached to a node

    Returns boolean

  • get type(): string
  • Retrieves the type of this mutable subclass as the name of the runtime class

    Returns string

    The type of the mutable

Methods

  • Collect applicable attributes of the instance and copies of their values in a Mutator-object. By default, a mutator cannot be extended, since extensions are not available in the object the mutator belongs to. A mutator may be reduced by the descendants of Mutable to contain only the properties needed.

    Parameters

    • _extendable: boolean = false

    Returns Mutator

  • Updates the attribute values of the instance according to the state of the mutator. The mutation may be restricted to a subset of the mutator and the event dispatching suppressed. Uses mutateBase, but can be overwritten in subclasses

    Parameters

    • _mutator: Mutator
    • _selection: string[] = null
    • _dispatchMutate: boolean = true

    Returns Promise<void>

  • Set the camera to perspective projection. The world origin is in the center of the canvaselement.

    Parameters

    • _aspect: number = ...

      The aspect ratio between width and height of projectionspace.(Default = canvas.clientWidth / canvas.ClientHeight)

    • _fieldOfView: number = ...

      The field of view in Degrees. (Default = 45)

    • _direction: FIELD_OF_VIEW = ...

      The plane on which the fieldOfView-Angle is given

    • _near: number = ...
    • _far: number = ...

    Returns void

  • Set the camera to orthographic projection. Default values are derived the canvas client dimensions

    Parameters

    • _left: number = ...

      The positionvalue of the projectionspace's left border.

    • _right: number = ...

      The positionvalue of the projectionspace's right border.

    • _bottom: number = ...

      The positionvalue of the projectionspace's bottom border.

    • _top: number = ...

      The positionvalue of the projectionspace's top border.

    Returns void
