Physically Based Rendering with Python

Blender add-on to import base materials, lights and cameras from https://api.physicallybased.info

Ray tracing engine (Python) - a very basic implementation.

Official implementation of the paper "Image-based Reconstruction of Heterogeneous Media in the Presence of Multiple Light-Scattering"

[SUPERSEDED - See V3.2] Welcome to the central hub for the Unified Information-Density Theory (UIDT) A Transformative framework that redefines the bedrock of physics by positioning information as the core entity from which space, time, matter, and energy arise

物理光照墙面渲染引擎：天文/大气/光追驱动的窗光 + 朱红叠字 | Physically-based wall renderer: astronomy-driven window light + vermilion text overlay

Python validation of a non-spectral, real-time fluorescent material model (Belcour, Fichet & Barla, SIGGRAPH 2025) and of its Godot 4.6 shader port, checked against full per-wavelength references.

Causal explorer for decomposed NeRF–surface light transport in physics-based inverse rendering.

A pure-CPU Python renderer that compares rasterization, ray casting, Whitted ray tracing, radiosity, and PBR path tracing in a shared Cornell Box. It emphasizes energy conservation, reproducible validation, and maintainable architecture.
