InheritanceNullBounds Inheritance BoundingVolumeBase Inheritance Object

NullBounds represents a debug bounding "volume" that is either considered always in, or always out of the frustum. NullBounds is useful for entities that are always considered in the frustum, such as directional lights or skyboxes.


Public Properties
 PropertyDefined By
 InheritedaabbPoints : Vector.<Number>
[read-only] Returns a vector of values representing the concatenated cartesian triplet of the 8 axial extremities of the bounding volume.
BoundingVolumeBase
 InheritedboundingRenderable : WireframePrimitiveBase
[read-only] Returns the bounding renderable object for the bounding volume, in cases where the showBounds property of the entity is set to true.
BoundingVolumeBase
 Inheritedmax : Vector3D
[read-only] The maximum extreme of the bounds
BoundingVolumeBase
 Inheritedmin : Vector3D
[read-only] The minimum extreme of the bounds
