DisplayXR Browser

A developer-preview, Chromium-based browser that renders the whole web normally and weaves glasses-free inline-3D for inline-3d WebXR pages on DisplayXR hardware. It is the productization of the Step B Chromium patch (displayxr-inline-3d) from the runtime roadmap.

This is a developer preview, not a maintained daily driver. It is a demo / reference-implementation artifact with a bounded maintenance policy — see the packaging plan. Do not use it for sensitive browsing; use your primary browser for banking, etc.

What it is

• It is Chromium — every website works. The only delta is the inline-3D surface: the inline-3d WebXR session mode + XRDisplayLayer bound to a DOM element, and the GPU-resident weave path.
• On a DisplayXR panel with the runtime + a display plug-in installed, inline-3D pages weave glasses-free 3D at their element rect while the surrounding 2D page stays flat. On any other machine / a 2D monitor, the weave silently no-ops and it is an ordinary browser.
• Windows / D3D11 + DirectComposition only (that is where the weave path lives today).

Relationship to other repos

Repo	Role
displayxr-runtime	The OpenXR runtime + the Step-B patch design/spec (docs/roadmap/webxr-step-b-design.md §13, displayxr-browser-preview.md). The actual Chromium patch is validated against this runtime + a display plug-in.
displayxr-browser (this repo)	The fork productization: the inline-3D patch as a rebaseable series over a pinned Chromium milestone, plus fetch/build/brand/package/sign scripts and release automation.
displayxr-web	Inline-3D web samples + optional JS helper (the analog of immersive-web/webxr-samples). The three.js demo the browser navigates to.
displayxr-cef-host	Step-A native OSR stand-in — a different artifact; not the browser product.

Status

Planning / scaffolding. No build yet. The working patch currently lives on branch displayxr-inline-3d in a local Chromium checkout; capturing it here (P1) follows the P0 official-build spike. Tracking issue: displayxr-runtime#733.

Planned layout

patches/     the inline-3D patch as a .patch series over the pinned Chromium milestone tag
scripts/     fetch (depot_tools + checkout) / build (official static) / brand / package / sign
branding/    product name, icons, about-page, user-agent strings
docs/        maintenance policy, rebase runbook, integration-point file list

Build (planned — see the packaging plan)

Phased: P0 official-build + rebrand spike (gate) → P1 patch series + scripts here → P2 signed installer chaining the runtime + display plug-in → P3 GitHub Release + download → maintenance policy. Full plan: displayxr-browser-preview.md.
