feat(web): add an interactive 3D device workspace

[juliusmarminge]

The device panel hides useful controls in the tools drawer and presents a plain stream. This web spike adds an interactive 3D device view, puts common actions beside the screen, and keeps flat mode available at any time.

Expo Device Hub still owns discovery, streaming, and input. Shared client-runtime code borrows decoded frames into a retained canvas, projects pointer input onto the display, and renders after frames or interactions. The web shell loads Three.js lazily, supports trackpad orbit and keeps its toolbar floating on the right in both modes at every panel width. The toolbar overlays the 3D stage; flat mode reserves only the rail width so controls never cover the live screen. Pinch zoom is removed. Resizing commits canvas allocation with redraw to avoid flashing.

The ordinary phone and iPad viewer uses shared quaternion motion, release prediction and nearest-view snapping. Cumulative camera-space drag moves a spring target; release chooses the closest screen-facing view and retains nearby yaw. Captured screen touches freeze motion and framing. A separate center/distance spring frames actual assembly bounds, including accessories, and stops requesting animation frames at rest. Pinch event normalization and input ownership hooks live in this base layer; device-specific pinch behavior belongs to its consumer.

Read-only ARM64 inspection of Bitrig 0.25 build 2500 recovered the drag gain of 0.006 radians per point, a 1.2-radian drag-force limit, velocity limits of 7.5 and 9 radians per second, an 85 ms prediction, a 65% gesture / 35% current-velocity blend and response/damping values of 0.5 / 0.78. These are disassembly findings. Our rest-view geometry is reconstructed for the models.

The viewer supports iPad and Android family silhouettes and actual Apple bodies for iPhone 18 Pro, iPhone 18 Pro Max, and 13-inch iPad Pro M5. Models load only in 3D mode and preserve geometry and pose through rotation and resizing. Unsupported hardware, failed downloads, and invalid assets retain procedural bodies. The 11-inch iPad and Android currently use procedural models. The 13-inch M5 iPad has an attach/detach Magic Keyboard button in its 3D controls. The accessory loads on demand, has independent cancellation and resource ownership, and retains the existing iPad geometry, framebuffer, renderer and pose. The camera frames the whole assembly, without reserving toolbar space. Flat mode hides the accessory and retains its selection for returning to 3D. Attaching in portrait requests landscape through the existing Device Hub input client. The keyboard uses a fixed hinge angle and does not add clickable keys.

Quick controls and the advanced drawer share confirmed settings. Screenshots capture native pixels through the selected host's credentials. MJPEG, accessibility overlays, unavailable WebGL, compact viewers, and mobile retain flat presentation. This implementation is web only; desktop uses the web view. The existing device-host and remote connection architecture remains in place.

Asset provenance, checksums, and a Blender conversion script are included. Converted GLBs retain body proportions and compress textures to about 1.7–2.3 MB per asset. The Magic Keyboard is exported separately in the iPad’s coordinate system. Apple asset redistribution rights remain unconfirmed.

Validation: 59 tests passed across 14 focused files. They cover frame ownership, input and orientation projection, gesture ownership, demand rendering, atomic resize, model selection/cancellation/cleanup/fallback, generated screen UVs, procedural families and camera attachment, settings races, screenshot access, subscription teardown, and accessory framing. Scoped web/client-runtime typechecks, targeted lint, and the web production build passed. React Doctor found no errors. Browser verification exercised the live iPhone and 13-inch iPad, screen input, orbit, rotation, flat view, panel resizing, and keyboard attach/detach. Opening Settings through the attached iPad confirms input projection after the camera shifts. Focused accessory tests cover retained device and screen resources, camera framing, compatibility, cancellation and cleanup. A fresh Android browser pass remains pending after the emulator exited.

Latest toolbar verification exercised normal-phone 3D and flat modes at 1280 and 940 pixels wide. The rail remained on the right and pinch did not zoom. Targeted gesture tests, web typecheck and lint passed.

The final narrow-panel review pass also confirms the flat framebuffer fits beside the floating rail. Canvas presentation failure now stops the stream with a visible error. The follow-up passed 38 focused tests, scoped web/client-runtime typechecks, and targeted lint.

The shared-physics update passed 23 focused tests in five files, scoped web/client-runtime typechecks and targeted lint. Tests cover refresh-rate independence, release speed bounds, interruption, captured input, finite idle rendering, assembly framing, retained model/accessory ownership and Chrome/Safari gesture normalization. React Doctor found no errors; its warnings concern existing complexity/export patterns and a download URL that the component already revokes. Browser verification exercised the live ordinary iPhone spring on the base branch.

Shared physics is owned here. The stacked Duo draft supplies fold-specific view candidates, hinge compensation, gestures and native display handoff.

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This is a large production-path feature that replaces the existing device panel with a default interactive 3D/WebGL workspace, new model assets, input/orientation plumbing, screenshots, and desktop IPC. It also introduces static-analysis suppression directives and has an unresolved orientation desynchronization risk when input is disconnected.

Not approved because:

@coderabbitai resolve

The only new CodeRabbit finding on 68aaf83, discussion_r4058219295, is disproven by raycasting the actual plate mesh at every camera ring center. Each ring overlaps the real surface by 0.003 units. Source evidence and measurements are in the thread reply; the prior findings were already fixed/resolved. No code change or approval is requested.

[coderabbitai]

@juliusmarminge The raycast measurements against the actual beveled plate mesh invalidate the remaining camera-ring attachment finding. The reported 0.003-unit overlap confirms that each ring intersects the real plate surface.

No code change or approval is needed.

Learning: In `packages/client-runtime/src/device/phoneScene.ts`, the `cameraPlate` uses Three.js `ExtrudeGeometry` with `depth: 0.025` and `bevelThickness: 0.007`. Its planar front cap is at local z=0.032, not z=0.025. Camera-ring attachment must be evaluated against the actual beveled geometry, such as with raycasts, rather than an assumed un-beveled front face or an AABB.

The Magic Keyboard was above the iPad after Reset 3D view. Reset now restores the iPad's landscape orientation with the keyboard below the display, and the Rotate device control is disabled while the keyboard is attached. Without a keyboard, Reset restores portrait orientation.

Before — keyboard above the display

After — keyboard below the display after Reset

Short recording: orbit and reset the iPad with its keyboard attached

Verified in the isolated browser panel; 57 focused device tests, web typecheck, and targeted lint pass.

The keyboard toggle commits keyboardAttached even when the input socket is disconnected. In that state setOrientation("landscape_right") is silently dropped by the stream client, and reconnect only reports connectivity—it does not replay the requested orientation—so the 3D keyboard remains attached while the simulator stays in its prior orientation. Disable this action when input is unavailable or retain and resend the pending orientation on reconnect.

packages/client-runtime/src/device/stream.ts:865

setOrientation silently drops the requested orientation until the iOS input WebSocket is open. The 3D keyboard control is enabled whenever video is streaming, but it does not require inputConnected; iOS video can reach streaming while connectIosInput is still waiting for the MJPEG prime. Clicking Attach in that interval updates the keyboard UI but send discards the orientation packet, and nothing retries it after the socket opens, leaving the simulator in portrait.
