Apr 1, 2026April 2026 — Focused on strengthening WebGPU integration and rendering performance in mrdoob/three.js. Delivered cross-context render bundle reuse and render-context aware constructor updates, enabling more flexible multi-context rendering with lower setup overhead. Implemented performance optimizations by caching light data per frame in NodeMaterialObserver and pooling per-uniform update-range objects in UniformsGroup, reducing CPU-GPU churn and redundant updates. Also fixed critical issues in the WebGPURenderer, including render bundle reuse correctness across render contexts and proper handling of layerUpdates for compressed array textures. Result: smoother frame times, better scaling on WebGPU-enabled devices, and more maintainable rendering code.

Aug 1, 2025August 2025 monthly summary for mrdoob/three.js: Delivered two critical feature sets that advance WebGPU rendering and multi-view capabilities. HDR support for the WebGPURenderer introduces an extended sRGB color space, half-float output, and configurable tone mapping, with updated color-space management to improve visual fidelity in HDR pipelines. Multi-camera viewport support enables accurate multi-view rendering by introducing a camera array and per-camera viewport (cameraViewport), along with refactored camera matrices to ensure correct positioning and projection across views. Minor bug-area refinements accompany these features, addressing color-space edge cases and camera-matrix accuracy to support robust rendering. Business impact includes higher-fidelity visuals in HDR workflows, enabling VR/multi-view scenarios, and laying groundwork for future performance optimizations and broader WebGPU adoption.
