3Delight

3Delight is a production-oriented rendering engine for 3D computer graphics developed by 3Delight Software. It is designed to deliver photorealistic imagery and is compatible with the RenderMan standard, enabling artists to work with familiar shading languages and scene description workflows. The renderer is intended to fit into standard production pipelines and offers integration through plug-ins and interfaces for popular 3D packages.

Its feature set includes physically based rendering with path tracing and other global illumination methods, support for displacement, volumes, subsurface scattering, and hair. It provides both unbiased and biased rendering options and supports multiple light transport paths, texture maps, and instancing. The renderer outputs high dynamic range image data and common image formats, and can produce multi-pass or multi-layer renders to support compositing.

3Delight can operate as a standalone renderer or be driven by a RenderMan-compatible API within a host package. It aims to provide predictable, stable results across scenes of varying complexity and is used in film, television, and advertising production pipelines.

Licensing is commercial, with options for studios and individual artists, including trial and educational licenses in some releases. The product has undergone ongoing development and updates, reflecting evolving industry standards and shading technologies.
