PROFILE
Johnathon Selstad
Over a three-month period, this developer contributed advanced 3D graphics features to the mrdoob/three.js repository, focusing on stereo rendering and global illumination. They enhanced the Screen Space Global Illumination (SSGI) pipeline by improving sampling, noise reduction, and demo usability, and introduced a Cornell Box-inspired scene to showcase lighting effects. Their work on anaglyph stereo rendering included implementing multiple algorithms and color modes, as well as upgrading the AnaglyphEffect for physically-correct depth perception using frameCorners(). Leveraging JavaScript, WebGL, and WebGPU, they delivered technically robust solutions that improved visual fidelity and flexibility for 3D content creators and developers.

Sep 1, 2025September 2025 (2025-09) performance highlights for mrdoob/three.js:Delivered major SSGI stability, accuracy, and demo usability improvements in the WebGPU/post-processing pipeline, and added a Cornell Box-inspired scene to the SSGI example to illustrate lighting variations. Improvements addressed sampling asymmetry, GI blending, radius/step handling, temporal noise and filtering, and ghosting/smearing; and enabled panning in the demo. These changes enhance visual fidelity, reliability, and collaboration workflows, while providing a clearer baseline for SSGI demonstrations across diverse lighting conditions.
