Summary of Changes

Hello @wang1212, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on a significant refactoring effort to remove legacy RBush spatial indexing code across several core packages, streamlining the rendering pipeline and object querying. Concurrently, it introduces a new experimental API for batch attribute updates, aiming to improve performance for complex rendering scenarios. The changes impact how dirty rectangle rendering and object selection are handled, moving towards a more direct bounding box-based approach.

Highlights

  • Legacy Code Removal: The pull request removes deprecated RBush spatial indexing components and related logic from @antv/g-lite, @antv/g-canvas, and @antv/g-plugin-annotation. This includes removing RBushNode interfaces, rBush properties, and associated event listeners and methods for dirty rectangle rendering and object querying.
  • Performance Improvement: An experimental setAttributes API has been added to DisplayObject in @antv/g-lite. This new method allows for batch updating of attributes, with an option to skip dispatching AttrModifiedEvent for potential performance gains.
  • Dirty Rectangle Rendering Update: The Canvas renderer's dirty rectangle rendering mechanism has been refactored to no longer rely on RBush for searching dirty objects. Instead, it now directly uses elementsFromBBox for region queries.
  • Documentation Updates: Relevant documentation files have been updated to reflect the removal of RBush as an acceleration structure for dirty rectangle rendering and region queries.

Code Review

This pull request removes the legacy RBush spatial indexing system from the rendering pipeline, specifically impacting dirty rectangle rendering and spatial queries in CanvasRendererPlugin and SelectablePlugin. The changes involve deleting RBush-related interfaces, properties, and logic, with elementsFromBBox now handling spatial queries without RBush. Additionally, an experimental setAttributes API is introduced in DisplayObject for batch attribute updates, offering an option to skip event dispatching for performance. Review comments highlight a leftover commented-out return statement in the setAttributes method and critically note that the documentation for elementsFromBBox still claims it is "fast," which is misleading given the performance regression from an RBush-based lookup to an O(n) scene graph traversal.
