With the latest release Diligent Engine enables support for arguably the most innovative GPU capability of recent years: hardware-accelerated ray tracing. Ray tracing is supported in D3D12 and Vulkan backends and is exposed through common easy-to use yet fully exhaustive API: exactly the same host code works in both backends. Similar to other shader types, ray-tracing shaders authored in HLSL will work in both backends verbatim. Vulkan backend also supports GLSL as well as SPIRV bytecode. A new tutorial demonstrates how ray tracing API in Diligent Engine can be used to simulate physics-based light transport in a scene to render soft shadows, multiple-bounce reflections and refractions, and dispersion.
