AutoGineer summary
Written by AutoGineer from the skill’s own files, not by the author
The Omniverse Realtime Viewer skill acts as a central orchestrator for developing USD-based viewer applications. It provides a structured approach to selecting implementation recipes, enforcing architectural conventions, and managing dependencies. By utilizing a set of focused reference documents, it guides developers through the lifecycle of building, configuring, and validating viewer applications, ensuring consistent behavior across different delivery paths such as local workstations or streaming environments.
What it does
- Routes development requests to specific implementation recipes based on the target delivery path.
- Enforces architectural rules for USD rendering, stage management, and UI integration.
- Provides guidance on camera selection, input handling, and viewport interaction.
- Standardizes the integration of AOV switching and render product configuration.
- Facilitates the capture of validation evidence for viewer readiness.
- Maintains separation between user-provided USD files and application-specific session state.
When to use it
- When initiating the development of a new USD viewer application within the Omniverse ecosystem.
- When determining the appropriate delivery path for a viewer, such as local native or streaming.
- When needing to implement consistent camera, selection, or UI behavior across viewer projects.
- When integrating advanced rendering features like AOV switching into an existing viewer.
Advantages
- Ensures architectural consistency across diverse viewer implementations.
- Provides a clear, modular path for adding specific capabilities like input routing or data display.
- Promotes clean separation of concerns between stage data and viewer-owned state.
- Standardizes the validation process for consistent delivery.
Usage examples
- “I need to build a browser-based viewer for USD files.”
- The agent will route you to the streaming viewer recipe, providing guidance on WebRTC stream setup, UI integration, and viewport interaction.
- “How do I implement AOV switching in my local USD viewer?”
- The agent will provide the AOV switching reference, detailing how to map render vars and update the display state on the server.

Omniverse Realtime Viewer
This is the top-level entry point for the Omniverse Realtime Viewer skill package. It is self-contained: all required routing, conventions, and validation guidance live in the selected references.
Use the focused reference documents as implementation recipes. This file chooses the right recipes and preserves the architectural rules that must hold across all generated viewer apps.
Instructions
Start by classifying the requested viewer, then read only the references needed
for that delivery path and feature set. Implement the render path first, layer
interaction and UI behavior on top of it, and finish by capturing validation
evidence from references/validation.md.
Read Order
Read
references/routing.mdto choose the delivery path and focused references.Read
references/conventions.mdbefore implementing camera, input, selection, viewport, streaming protocol, scene loading, or environment behavior.For broad viewer requests, read
references/usd-viewer-app/README.md.If the delivery path is unclear, read
references/streaming-vs-local/README.md.If the prompt includes layout, panels, controls, inspectors, status, or UX, read
references/viewer-ux-workflow/README.mdand then the focused viewer UI references. This applies to React/WebRTC, Tauri, Electron,ovui,ovwidgets, and Dear ImGui apps; "frontend" means user-facing UI, not only browser UI.For viewport interaction, read
references/viewer-input-routing/README.mdbeforereferences/camera-controls/README.md,references/native-picking-selection/README.md, orreferences/object-selection/README.md.Read only the focused capability references needed for the requested app.
Use
references/validation.mdto capture review evidence before handoff.
Non-Negotiables
Use
ovrtxfor all USD and 3D rendering.Browser apps display an
ovstreamWebRTC video stream plus UI. The browser does not render USD geometry.Do not substitute WebGL, Three.js, Babylon.js, PlayCanvas, A-Frame, model-viewer, react-three-fiber, glTF browser viewers, or other client-side 3D renderers.
If local validation cannot run because the GPU/runtime environment is absent, scaffold the
ovrtxpath and document the runtime requirement. Do not add a browser-renderer fallback.Keep user USD files unmodified. Viewer cameras, render products, render vars, settings, selection metadata, and runtime state belong in session/composite layers or app state.
Keep one owner for
renderer.step(), stage mutation, native picking, selection writes, and live attribute writes.Keep dependency acquisition in
references/dependencies/README.mdand deployment choices inreferences/cloud-deployment/README.md; do not duplicate package locations or deployment setup.

Build Workflow
Classify the prompt by delivery path, target user, required capabilities, runtime environment, validation needs, and explicit constraints.
Select a small reference set. Start with the recipe or routing reference, then add focused capabilities such as camera, picking, hierarchy, properties, render settings, transform tools, cloud assets, or deployment.
Read selected references before writing app code. Follow their build order, import order, data-channel contracts, and renderer ownership rules.
Implement the core render path first, then input routing and camera, then selection and data panels, then scene/settings features, then packaging or deployment.
Treat the selected references as the behavior contract for API shape, compatibility, and generated project structure.
Capture validation evidence before calling the viewer ready.
Examples
For a browser viewer request, use the streaming recipe references plus camera, picking, hierarchy, properties, render settings, and stream-status references.
For a local workstation viewer request, use the local or native delivery references plus renderer setup, stage loading, viewport input, and validation.
Completion Checklist
Selected references match the user's intent and delivery path.
No code path uses a browser-side 3D renderer for USD.
The generated app has one clear owner for render stepping and stage mutation.
User USD files remain untouched by viewer-owned session data.
Camera, input, selection, scene loading, and stream behavior follow
references/conventions.md.Setup/build/run results and visual interaction evidence are captured with
references/validation.md.

Viewer Data View Patterns
Triggers
Use this skill for stage tree, outliner, hierarchy, asset browser, property inspector, JSON tree, metadata display, list/grid/canvas choice, selected object panel, or cross-panel selection state.
Use this with stage-hierarchy, stage-queries, stage-attribute-reads, prim-info-display, and viewer-backend-interface.
Choose The Data View
| Data shape | View model |
|---|---|
| USD prim hierarchy, folders, nested objects | Tree View |
| Ordered results, logs, recent files, flat commands | List |
| Asset thumbnails, scene cards, visual browsing | Grid |
| Free-positioned graph/node layout | Canvas |
| Arbitrary nested object/array payload | JSON Tree |
| Selected object details | Property Inspector |
Do not force hierarchy into a flat list unless the user asked for search-only results. Do not use a tree for flat data; false nesting makes scan paths harder.
Selection Contract
Selection is a shared application signal, not private tree state.
Outliner/tree/list/grid views emit canonical prim paths or asset IDs.
Viewport, property inspector, status surfaces, and backend selection/highlight subscribe to that signal.
Single-select is the current default for viewer apps. If multi-select is added, every subscriber must explicitly support mixed values and multi-highlight.
Clear dependent data when selection clears or stage changes. Never show stale properties from a previous stage.
With ViewerBackend, prefer:
await backend.selectPrims(paths);
const props = await backend.getProperties(path);
const tree = await backend.getStageTree(rootPath);Stage Tree Pattern
Tree rows should include:
Expand/collapse affordance for parents only.
Type icon or compact type label for every row.
Prim display name, with full path available through title/tooltip/details.
Selection state with a visible row highlight.
Optional badges for visibility, variant, unloaded, hidden, or error states when the backend provides them.
Indent by depth using a stable unit, typically 12-24 px depending on panel density. Leaf rows should not reserve chevron hit space unless the existing tree component requires it; the visual rhythm should still make parent/leaf differences clear.
For large stages:
Lazy-load children when possible.
Keep expansion state by prim path.
Virtualize long flat sibling lists.
Preserve expansion where paths still exist after reload.
Debounce search/filter input and show match counts.
Asset Lists And Grids
Use grids for visual browsing with thumbnails or previews.
Use lists/tables when names, paths, modified dates, or statuses matter more than thumbnails.
Surface loading, missing preview, incompatible asset, and permission/error states per item with status tags or inline row messages.
Selecting an asset should update preview/detail state; loading an asset into the viewer should be an explicit action unless the product brief says preview-on-select.
Property Inspector Pattern
Use a two-column scan line for dense properties:
[right-aligned label] | [left-aligned control/value]Use a 96 px label column for compact panels and 120 px for wider panels.
Group dense fields by category: Transform, Material, Visibility, Variants, Bounds, Metadata.
Show common groups expanded; advanced groups collapsed.
Use compact tuple rows for XYZ, RGB/RGBA, UV, and similar fixed-arity values.
Use read-only rows when the backend does not support editing a field.
For mixed or unsupported values, show an explicit display state instead of an empty input.
No selection state should show a plain-language placeholder such as "Select an object to view its properties." Invalid selection after scene switch should clear the inspector.
JSON And Metadata Display
Use JSON Tree only for arbitrary nested payloads such as raw metadata, message traces, diagnostics, or backend debug output. For known USD properties, prefer a typed inspector.
Color/type-code JSON values with text labels or accessible semantics; do not rely on color alone.
Collapse deeply nested objects by default.
Cap or summarize large arrays and binary-like values before rendering.
Keep copy-path or copy-value actions near the row when useful for debugging.
Cross-Panel Tests
Validate these flows when you add or change data views:
Selecting a tree row highlights the viewport object and updates the property inspector.
Clicking empty viewport or clearing selection clears dependent panels.
Switching scenes clears stale hierarchy, properties, and selection before loading new data.
Search/filter does not change the canonical selection unless the user selects a filtered result.
Loading/error/empty states are visible and do not collapse panel layout.
