UeBoxHelper

A helper class that creates and updates a wireframe bounding box around a 3D object. Useful for visual debugging or highlighting the bounding volume of an object.

---

Constructor

new UeBoxHelper(object = undefined, color = #FFFF00, data = {})

Inherits from UeLineSegments

Data parameters

Name	Type	Default	Description
object	Object	undefined	The 3D object to create the bounding box for
color	Color	#FFFF00	Color of the bounding box lines
data	Object	{}	Additional data to pass to the base class

Properties

Property	Type	Description
object	Object	The target 3D object
color	Color	Color used for the bounding box
material	UeLineBasicMaterial	Material used for the bounding box

Methods

updateBox()

• Updates the bounding box geometry based on the current state of the target object.

• Computes the bounding box from the object's geometry.

• Rebuilds the line vertices representing the box edges.

• Applies the object's transform (position, rotation, scale) to the bounding box helper.

setFromObject(object)

Updates the helper to track a new object.

Parameter	Type	Description
object	Object	The new object to track

Usage Notes

• The bounding box updates automatically on creation.

• Call setFromObject() to change the target object and update the box.

• The helper copies the transform of the tracked object to maintain correct positioning, rotation and scaling.
