PROFILE

Llijjing

Worked on the mrdoob/three.js repository, focusing on core rendering pipeline improvements using JavaScript, WebGL, and WebGPU. Delivered targeted bug fixes to enhance rendering correctness and stability, including a face culling correction for WebGPU that tracked mesh orientation changes and updated the rendering pipeline based on the world matrix determinant. Addressed depth sorting consistency by revising the sorting logic to negate projected Z-values, ensuring renderOrder semantics were maintained with reversed depth buffers across both WebGL and common renderers. Collaborated with other contributors to refine implementation details, resulting in more reliable and predictable rendering behavior for developers using three.js.

June 2026 monthly summary for mrdoob/three.js: WebGPU Rendering - Correct Face Culling fix delivered to address artifacts when mesh orientation changes. Implemented tracking of frontFaceCW in needsRenderUpdate and triggered a pipeline update when the world matrix determinant is negative, ensuring correct face ordering across orientation changes. This reduces visual artifacts in the WebGPU path and improves rendering stability for developers relying on WebGPU.
