ibgreen · 2026-11-07T18:25:45Z

Follow up of #11053.

Background

HexagonLayer uses CPU aggregation on WebGPU. Add compute binning with independent color and elevation channels and explicit domains.

Change List

Add hexagonal bin assignment to the shared reducer
Preserve CPU fallbacks and device-buffer limit checks
Feed GPU results directly to the cell layer
Hide empty cells with a WGSL-safe NaN check
Preserve integer-weight fallback across prop-only updates
Unit tests
Documentation

Refreshed against master after #11018/#11019. Build, lint, nine Hexagon tests, 119 Node tests and two WebGPU golden comparisons pass; final CI is green, including coverage, WebGPU and website checks. Picking, extensions and automatic domains remain follow-ups.

Confidence Score: 5/5

[Medium impact] The PR appears safe to merge; no actionable issues remain.

Summary

Adds WebGPU aggregation to HexagonLayer when both domains are supplied.

HexagonLayer aggregates supported data with WebGPU compute.

The four earlier, unnumbered findings are addressed in the current code. No new actionable issues were found. Tests were not run during this review.
