A directional light is defined by a direction (what a surprise!). The light is emitted from everywhere in the specified direction, and has an infinite range. An example of a directional light is when a distance planet is lit by the apparently parallel lines of light from its sun. Light in a downward direction will light the top of an object.

    Parameters

    • effect: Effect

      The effect to update

    • lightIndex: string

      The index of the light in the effect to update

    Returns DirectionalLight

    The directional light

  • transferToNodeMaterialEffect(effect: Effect, lightDataUniformName: string): Light
  • Add a new node constructor

    Parameters

    • type: string

      defines the type name of the node to construct

    • constructorFunc: NodeConstructor

      defines the constructor function

    Returns void

  • Construct(type: string, name: string, scene: Scene, options?: any): Nullable<() => Node>
  • Returns a node constructor based on type name

    Parameters

    • type: string

      defines the type name

    • name: string

      defines the new node name

    • scene: Scene

      defines the hosting scene

    • Optional options: any

    Returns Nullable<() => Node>

    the new constructor or null

  • Creates a new typed light from the passed type (integer) : point light = 0, directional light = 1, spot light = 2, hemispheric light = 3. This new light is named "name" and added to the passed scene.

    Parameters

    • parsedLight: any

      The JSON representation of the light

    • scene: Scene

      The scene to create the parsed light in

    Returns Nullable<Light>

    the created light after parsing

  • ParseAnimationRanges(node: Node, parsedNode: any, scene: Scene): void
  • Parse animation range data from a serialization object and store them into a given node

    Parameters

    • node: Node

      defines where to store the animation ranges

    • parsedNode: any

      defines the serialization object to read data from

    • scene: Scene
