Kajiya is an experimental real-time global illumination renderer written in Rust on Vulkan, hybridizing rasterization, compute, and hardware ray tracing to approximate path-traced lighting in fully dynamic scenes without precomputed light transport. It is a hobby project that is no longer maintained, intended as an artisanal reference of rendering techniques rather than a production-ready renderer.
Use cases
- render dynamic scenes with real-time global illumination
- approximate path-traced reference lighting without precomputed light probes
- study how ray-traced shadows, specular, and irradiance caches are implemented
- learn real-time rendering techniques from a Rust and Vulkan codebase
- experiment with hybrid raster, compute, and ray-tracing pipelines
- render PBR scenes with energy-conserving GGX materials
When to choose
- you want to study modern real-time GI techniques like volumetric temporally-recurrent irradiance caches in working code
- you are experimenting with Rust and Vulkan for graphics programming
- you need a runnable renderer to visualize demo scenes with dynamic lighting
- you want to see 'artisanal hacks' and shortcuts used to hit real-time rates
When to avoid
- you need a fully-featured renderer to ship a game or support diverse scenes and hardware
- you expect maintenance, bug fixes, or updates, since the project is explicitly unmaintained
- you need a polished, reusable rendering library or engine with stable APIs
- your GPU lacks hardware ray tracing support
