Web 3D Gaussian Splatting renderer SparkJS released v2.2.0, shared by Fei-Fei Li.

Key changes: up to 20% faster splat sorting, up to 14% FPS gains on some systems via the WEBGLprovokingvertex extension, a 50% smaller bundle, WASM compiled only once (merged spark-worker-rs/spark-rs), pre-built bundles installable without a Rust toolchain, an experimental faster LoD traversal algorithm, and fixes including stale LoD chunk fetching after scene changes.
