Tracker: deck.gl v9.4 / v10

[ibgreen]

deck.gl v9.4

• Target Release Date: July 31, 2026

• Goal: Foundations for deck.gl v10 (WebGPU/Arrow/GPU Compute/Data Sources/LLM integrations)

• Themes:

  • loaders.gl 5.0 - Unbundled, arrow-first loaders.
  • View System Improvements for both non-geospatial and geospatial use cases
  • Widgets
  • Basemap Integrations

• Follows v9.3, v9.2, v9.1 and v9.0

loaders.gl v5.0

• Apache Arrow output @ibgreen
• SourceLoaders / Layers sharing data sources @ibgreen
• Unbundled Loaders @ibgreen
• ...

luma.gl v9.4 @ibgreen

• Arrow support @ibgreen @Pessimistress

Performance

• Picking 1 - Remove instancePickingColors @ibgreen - Save GPU buffer memory and init costs via shader builtin instance_index
• Picking 2 - Migrate from pickingColors to pickingIndexes @ibgreen
• Picking 3 - Migrate to luma.gl index based picking modules @ibgreen
• Culling 1 - Layer.getWorldBounds() @ibgreen feat(core) Add getWorldBounds() method #9920 - Prep for layer draw culling
• on "idle" callback. An event for signaling deck has settled (draws, async loading, etc), similar to maplibre.
