Research: native / RN gaussian splat rendering without a WebView

Answer

**Short version: yes, a WebView-free native path exists on iOS and it is genuinely good — but only on iOS, and only if you write the React Native bridge yourself. There is no…

Write the Session 1 spec (pose to splat rendering)

Inputs from #3 for this spec.

  • Viewer + format: Spark (@sparkjsdev/spark 2.1.0, MIT, WebGL2-only), assets as SOG or SPZ. .RAD LoD streaming exists for anything beyond room scale. -…

Decide: success gates and the measurement protocol

Input from #3 — two of your four gates cannot be set from literature.

There is no published splat frame-rate measurement inside WKWebView, anywhere. So ≥30fps and `<100ms pose-to-photo…

Research: WebGL2 splat viewer performance inside iOS WKWebView

Addendum — corrections and source-level additions

A deeper source-level pass (reading viewer source, not just READMEs, plus npm registry and default-branch commit dates) landed after the…

Decide: bake-off design — comparands, ground truth, decision rule

Reframed by #2 — the comparands have changed.

The original framing was visual relocalization against the splat vs BLE trilateration. #2 establishes that the first option does not exist…

Research: on-device visual relocalization against a gaussian splat

Answer

Researched 2026-08-11. Short version: nothing localizes a phone against a Gaussian splat on-device today. Splat-based localization is a 2024–2026 paper field that runs on desktop…

Configure and verify the three TG-BT5-IN beacons

Prerequisites established by #4 (part number corrected: TG-BT5-IN, not TG-BTS-IN):

  • Bring a magnet. Tags ship asleep — hold a magnet to the reed switch 3–10s to wake, then 5–10s…

Research: MikroTik TG-BTS-IN beacon capabilities and configuration

Answer

Product identity first: there is no MikroTik "TG-BTS-IN". The part number is TG-BT5-IN — "BT5" with a five, for Bluetooth 5. MikroTik ships exactly two Bluetooth tags:…
