## What it is
A Unity library that fractures any mesh at runtime using the NVIDIA Blast library, converting the mesh into physics-driven chunks with rigidbodies and breakable fixed joints. It handles UV generation for chunk interiors and keeps structures stable via frozen rigidbodies and an anchor graph traversal system.

## Use cases
- fracture a mesh into pieces when it is hit at runtime
- create destructible walls and structures in Unity
- make objects break apart into rigidbody chunks on impact
- simulate blast damage on 3D models in a game
- cut closed meshes into smaller physics chunks
- add destruction effects to a Unity game

## When to choose
- you need runtime mesh destruction in Unity with physics-driven debris
- you want NVIDIA Blast integration without writing the bindings yourself
- your meshes are closed and have vertices, triangles, and UVs

## When to avoid
- you target platforms other than x64 without sourcing the nvblast library yourself
- you need destruction in a non-Unity engine
- you need pre-baked or offline fracturing rather than runtime
- you require actively maintained code, as the latest release dates to 2021
