Class PointLight

Creates a new point light that can be added to the scene, for example:

const p = new PointLight();
p.diffuseIntensity = new Vector3(0.3, 0.3, 0.3);
p.specularIntensity = new Vector3(0.3, 0.3, 0.3);
this.scene.add(p);

draw

  • Draws this transform and all its children in the scene graph.

    Parameters

    • parent: Node3

      The parent transform of this transform.

    • camera: Camera

      The camera used to view the scene.

    • lightManager: LightManager

      The light manager used to manage the lights in the scene.

    Returns void

getLocalToParentMatrix

getType

intersects

  • Checks for intersection between this Node3 and another

    Returns

    Whether or not the two objects intersect

    Parameters

    • other: Node3

      The other Node3 object

    • mode: IntersectionMode3 = IntersectionMode3.BOUNDING_SPHERE

      The IntersectionMode3 to use for the comparison (default: BOUNDING_SPHERE)

    • space: CoordinateSpace3 = CoordinateSpace3.LOCAL_SPACE

      The CoordinateSpace3 to use for the comparison (default: LOCAL_SPACE)

    Returns boolean

lookAt

  • Rotates this Node3 object to look at the given target with the given up vector

    Parameters

    • target: Vector3

      The Vector3 representing the target in world space

    • up: Vector3 = Vector3.UP

      The Vector3 representing the up direction (defaults to Vector3.UP)

    • coordinateSpace: CoordinateSpace3 = CoordinateSpace3.LOCAL_SPACE

    Returns void

remove

  • Removes the current Node3 from its parent Node3

    Returns

    true if the Node3 was successfully removed, false otherwise

    Returns boolean

removeChild

setLights

setLocalToParentMatrix

traverseSceneGraph

  • Traverses the scene graph starting from this Node3 object and updates the world matrices of all Node3 objects in the graph.

    Parameters

    • parentMatrixDirty: boolean = false

    Returns void

updateLocalBounds

updateWorldBounds

updateWorldMatrix

  • Updates the world matrix of this Node3 by computing the multiplication of its local matrix with its parent's world matrix (if it has a parent).

    Returns
