Explore the experimental ray tracing features introduced in Unity 19.3 beta during this SIGGRAPH 2019 conference talk. Dive into DirectX ray tracing implementation without getting bogged down in algorithms, covering topics such as acceleration structure management, ray tracing shaders, API, authoring, and setup for HDRP. Learn about Unity DXR architecture, ray traced effects, indirect lighting, shadows, transparents, spatiotemporal sampling, denoising, and optimization techniques. Gain insights from Unity Technologies' DXR Graphics Developer Tianliang Ning in this 30-minute presentation, providing a comprehensive overview of getting started with DirectX ray tracing in Unity.
