## What it is
bepuphysics v2 is a pure C# 3D real-time rigid body physics simulation library targeting .NET 8. It provides collision shapes, constraints, continuous collision detection, and fast scene-wide queries with a focus on performance.

## Use cases
- simulate rigid body physics in a C# game
- add 3D collision detection to a .NET application
- build a character controller with physics
- run real-time physics simulations on any .NET-supported platform
- query scenes with rays and sweeps for hit detection
- create custom collidables like voxel terrain

## When to choose
- you need a fast, pure C# physics engine without native dependencies
- your project targets .NET 8 and cross-platform deployment
- you need rigid body dynamics with a wide range of constraint types
- performance is critical and you can use RyuJIT-capable compilers

## When to avoid
- you need a physics engine with extensive documentation and beginner-friendly APIs
- you require 2D physics simulation
- you need a battle-tested engine with large community ecosystem like PhysX or Jolt
- you dislike nonidiomatic APIs, as the library admits its APIs are unusual

## Facets
- artifact type: library
- maturity: active
- function: simulation, graphics, game-engine
- domain: simulation, cross-platform
- platform: cross-platform, windows
- tags: physics-engine, rigid-body-dynamics, collision-detection, csharp, dotnet, real-time-simulation, constraints, game-development, linux, macos
