A quick breakdown of lighting in the `restir-meets-surfel` branch of my renderer

A quick breakdown of lighting in the restir-meets-surfel branch of my renderer, where I revive some olde surfel experiments, and generously sprinkle ReSTIR on top.

General remarks

Please note that this is all based on work-in-progress experimental software, and represents a single snapshot in development history. Things will certainly change 😛

Due to how I'm capturing this, there's frame-to-frame variability, e.g. different rays being shot, TAA shimmering slightly. Some of the images come from a dedicated visualization pass, and are anti-aliased, and some show internal buffers which are not anti-aliased.

Final images

Convert legacy three.js (JSON) files to glTF 2.0

legacythree2gltf.js

Converts legacy JSON models (created by the three.js Blender exporter, for THREE.JSONLoader) to glTF 2.0. When original .blend files are available, prefer direct export from Blender 2.80+.

NOTE: JSON files created with .toJSON() use a newer JSON format, which isn't deprecated, and these are still supported by THREE.ObjectLoader. This converter does not support that newer type of JSON file.

Installation:

npm install canvas vblob three
