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 Control Patterns
Triggers
Use this skill for buttons, links, toolbar, action groups, camera tools, render settings forms, dropdowns, segmented controls, sliders, steppers, toggles, accordions, confirmations, destructive actions, or control semantics.
Use this with viewer-layout-patterns and the feature skill that owns the backend behavior, such as camera-controls, render-settings, aov-switching, or stage-management.
This guidance is client-agnostic. Apply the control intent and state rules to
the selected UI toolkit: React components, Tauri/Electron web UI, lightweight
ovui widgets, full-editor ovwidgets, or Dear ImGui controls. Transport- and
toolkit-specific skills still own event APIs, lifecycle, and rendering.
Intent To Control
Choose the control by user intent before styling it:
| User intent | Control |
|---|---|
| Execute a command or mutate state | Button or icon button |
| Navigate to another route/resource | Link |
| Choose one of 2-3 modes | Segmented control or radio group |
| Choose one value from 4+ options | Select/dropdown |
| Search and choose from a long list | Combobox |
| Toggle an immediate preference | Switch |
| Toggle a tool mode in a toolbar | Toggle button |
| Provide a numeric value with bounded steps | Number input, stepper, or slider |
| Provide text | Text input or textarea |
| Reveal optional content | Disclosure, collapsible group, accordion, or trigger button |
| Confirm a high-risk action | Dialog with grouped actions |
Semantic rule: if it changes application state, it is a button. If it moves the user to a location, it is a link. Visual style does not change semantics.
Toolbar Rules
Viewport tools belong near or over the Viewport Panel, not buried in a settings panel.
Keep the primary visible set small: orbit/pan/zoom, fit, reset camera, selection mode, screenshot if supported.
Put secondary tools behind overflow rather than shrinking icons below readable hit targets.
Use icon buttons for familiar tools and include accessible labels/tooltips.
Group related tools with separators or button groups; do not scatter Save/Cancel/Apply across unrelated regions.
Camera vocabulary matters:
| Term | Meaning |
|---|---|
| Orbit | Camera rotates around a target point. |
| Pan | Camera translates laterally in the view plane. |
| Dolly | Camera moves forward/back along depth. |
| Zoom | Magnification/focal change; not the same as dolly. |
| Fit | Reposition camera to frame the selected prim or full stage. |
Match labels and implementation to the actual camera operation from camera-controls.
Action Priority
Each action group should have at most one primary action.
| Priority | Use for |
|---|---|
| Primary | The intended next step: Apply, Load, Save, Connect. |
| Secondary | Alternatives: Cancel, Reset view, Close. |
| Destructive | Delete, clear, overwrite, reset stage, or other high-risk actions. |
Standard footer order is cancel/dismiss on the left and affirmative action on the right. If the affirmative action is destructive, keep it on the right but style it as destructive.
Form And Settings Controls
Every form control has a visible label. Placeholder text is a hint, not a label.
Store control state in application state. Controls render the value they are given and emit changes.
Use sliders for fast approximate tuning; pair with numeric input when exact values matter.
Use switches for immediate viewer preferences, checkboxes for submitted forms, and toggle buttons for active tools.
For render settings, render only backend-advertised capabilities. Clamp values before sending them to the backend and display the effective value, apply status, and reload requirement returned by the backend.
Disable controls only when the action cannot be performed. Prefer explanatory inline text or tooltip over silently disabled controls.
Disclosure And Menus
| Pattern | Use when |
|---|---|
| Disclosure icon | You only need an open/closed affordance; caller owns content. |
| Collapsible group | One custom section reveals arbitrary content. |
| Accordion | Multiple related sections, such as Transform/Material/Lighting categories. |
| Dropdown menu | A trigger reveals commands or navigation choices. |
| Select/combobox | The user is choosing a value for a form field. |
Do not put interactive controls inside a tooltip. Use a popover/overlay, drawer, or panel.
Confirmation Rules
Use confirmation dialogs for irreversible or structurally significant actions: deleting prims, clearing scene state, overwriting settings, disconnecting active work, or switching scenes with unsaved edits.
Do not confirm every small property edit. For incremental, reversible changes, show status and provide undo/reset where possible.

Requirements and compatibility
Written for: OpenAI Codex
Works with: Claude Code, Claude apps, OpenAI Codex, GitHub Copilot, Cursor, Gemini CLI, Kiro, OpenCode, Goose, Amp, Roo Code, JetBrains Junie, Factory Droid, Devin (ex-Windsurf), Mistral Vibe, OpenHands, Letta
“Works with” means the tool reads the open Agent Skills format; a skill written for one tool may use features others lack.
The author says: Orchestrator skill. Downstream focused references may require NVIDIA GPUs, ovrtx, ovstream, ovui, OpenUSD, Python, Node/React, Tauri, Electron, C++, or cloud GPU deployment access depending on the selected viewer path.
