Kajiya
Kajiya is a physically based rendering engine and real-time global illumination renderer. It utilizes a GPU-accelerated path tracer to simulate real-world material properties, such as roughness and metalness, to achieve photorealistic visual results.
The engine incorporates a temporal super-resolution upscaler to increase final render resolution by reconstructing images from lower-resolution internal frames. It also generates high-fidelity reference images through path-tracing to verify the visual accuracy of real-time lighting outputs.
The system covers 3D scene visualization and asset management, including the import of meshes and scene configurations. It further supports image-based lighting using high-dynamic range images to provide realistic ambient environmental illumination.
