Note: This tool requires uncompressed GLB files. Compressed or optimized GLB files may not generate correct BVH data.

A Bounding Volume Hierarchy (BVH) is a tree structure used to optimize spatial queries and collision detection in 3D scenes:

• Each node represents a bounding box containing a portion of the geometry
• The tree is organized hierarchically, with larger boxes containing smaller ones
• This structure enables efficient ray casting and collision checks

Hover over any part of the model to see its BVH data. The wireframe visualization shows the mesh structure, while the exported JSON contains detailed BVH information for each mesh.
