## What it is
RadeonRays is a ray intersection acceleration library developed by AMD, providing a C API for scene building and asynchronous ray intersection queries on CPU and GPU. It supports DirectX12 and Vulkan backends and works across a wide range of hardware platforms, not just AMD.

## Use cases
- accelerate ray intersection queries for ray tracing renderers
- build BVH scene structures for GPU ray tracing
- add ray tracing to a game engine via Vulkan or DirectX12
- write hardware-independent ray tracing code with a C API
- prototype path tracing or offline rendering algorithms

## When to choose
- you need a cross-vendor, multi-backend ray intersection library
- you want a stable C API for asynchronous GPU ray queries
- you are building a renderer or engine on Vulkan or DirectX12

## When to avoid
- you need full production ray tracing pipelines rather than intersection queries
- you target platforms without DirectX12 or Vulkan 1.2 support
- you need a higher-level rendering framework with shading built in

## Facets
