raytracingiin
Raytracingiin is a cross-platform, open-source framework for ray tracing designed to be accessible to researchers and developers. It provides a modular pipeline for generating images by tracing rays through scenes, supporting both path tracing for global illumination and conventional ray tracing for reflections and shadows. The project emphasizes readability and portability, with a reference implementation in C++ and optional back ends for CUDA, Vulkan, and DirectX Raytracing (DXR).
Origins and development: The project began as an educational effort in the early 2020s by a collaboration
Architecture: Raytracingiin organizes rendering into scene representation, ray generation, intersection, shading, and post-processing. It uses a
Algorithms and features: Supports stochastic sampling, next event estimation, multiple importance sampling, and both unidirectional and
Impact and reception: Used in teaching, research, and small-scale production. Its readable codebase and tests make
