InheritanceAxisAlignedBoundingBox Inheritance BoundingVolumeBase Inheritance Object

AxisAlignedBoundingBox represents a bounding box volume that has its planes aligned to the local coordinate axes of the bounded object. This is useful for most meshes.


Public Properties

 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.
