sparkjsdev/spark 发布 v2.4.0

2.4.0 (Oct 19, 2026) Bug fixes and improvements Enhancements Add SPZ v4 read support ( #484 ) ( @udwinj , @mrxz ) Decouple and abstract paged splat load logic from PagedSplat into FetchSource that retrieves data from in-memory file, URL or any other custom mechanism ( #463 ) ( @mrxz , @xohm , @oscarlorentzon ) Switch to flate2 from zlib-rs backend for RAD deflate compression. ~50% faster compression, ~2-5% smaller outputs and ~20% faster decoding ( #474 ) ( @mrxz , @oscarlorentzon ) Replace miniz_oxide with flate2 for Gzip (de)compression of SPZ files. Remove miniz_oxide as dependency ( #485 ) ( @mrxz ) Address stutter during animations. Skip unnecessary splat sortings if the splat buffer needs or has changed like for example when LoD levels change or splats animate / move ( #347 ) ( #460 ) ( @oscarlorentzon , @mrxz ) Refactor PagedSplats into its own separate file ( #462 ) ( @mrxz ) Remove outdated Github workflows CI commands ( #464 ) ( @mrxz ) Add Rust linter ( #414 ) ( @mrxz ) Improve tests ( #483 , #482 ) ( @mrxz ) Improve docs ( #478 ) ( @oscarlorentzon ) Bug Fixes (WebXR) Use camera projection projection matrix to calculate LoD pixel limit. The THREE.Camera fov value was incorrectly used before: It doesn't match the one reported by the WebXR API ( #488 ) ( @oscarlorentzon ) Adress view-dependent color precission loss due to unwanted SH coefficinets clamping ( #465 ) ( @oscarlorentzon ) Dispose the LoD index textures when renderer is disposed ( #479 ) ( @oscarlorentzon ) Fix issue with Level 3 Spherical Harmonics (sh3) dropped due to incorrect type assertions. It introduces explicit types in PackedSplats and ExtSplats instead of loose types + assertions. ( #467 ) ( @mrxz , @oscarlorentzon ) (WebXR) Fix issue with splat size and anti-alias blur rendered at half the correct width. Use whole viewport width for calculations instead of half ( #487 ) ( @oscarlorentzon ) Ignore errors / rejections after SparkRenderer is disposed. This can happen when for instance there's pending LoD sorting in parallel in the worker when the renderered is disposed ( #476 ) ( @oscarlorentzon ) Replace workers that hit a fatal error / crash / trap. The pool tried to reuse those in a broken state ( #480 ) ( @oscarlorentzon ) Fix issue with long thin splats drawn off axis, too wide or too narrow. Compute 2D covariance eigenvectors without cancellation ( #486 ) ( @oscarlorentzon ) Stop retrying a failed level of detail tree on every update ( #477 ) ( @mrxz , @oscarlorentzon ) Address raycasting precission and speed issues ( #469 ) ( @n3ur0m4n , @oscarlorentzon ) 官方 Release：v2.4.0。请查看 Release notes、依赖和许可证变化。
