Box3Helper

Box3Helper ⟵ Line ⟵ Object3D

A helper class for visualizing Box3 using Line geometry.
Box3Helper creates a wireframe representation of a Box3 (axis-aligned bounding box) using line segments, useful for debugging, visualization, and spatial reference.

• Shows Box3 min/max boundaries as wireframe
• Changeable color for the wireframe
• Automatic geometry generation from Box3
• Updates when Box3 changes
