Acceleration Structures allow application developers to perform spatial queries against primitives and procedural geometry, which is useful for photorealistic visualizations, physics simulations, and video games. Independent hardware vendors such as AMD, Qualcomm, and NVIDIA have invested in providing hardware accelerated spatial queries in their recent ASIC products, which has popularized Microsoft DirectX Ray Tracing in the latest applications and games.
