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.

Omniverse Realtime Viewer Routing
Use this reference to route plain-language viewer requests into focused references.
This routing reference is self-contained; focused references live in sibling
directories under this references/ directory.
Architectural Constraint
All USD and 3D rendering must use ovrtx, NVIDIA's RTX renderer.
The pattern is always:
Server-side: Python or native process owns
ovrtx.Rendererplus OpenUSD stage access, then renders frames on the GPU.Browser delivery:
ovstreamWebRTC streams rendered frames to a browser. The browser displays video plus UI overlays.Desktop delivery:
ovuinative windows, Tauri WebViews, C++ windows, or Electron SHM pixel transport displayovrtxrendered frames.
If local validation cannot run because the GPU/runtime environment is absent,
scaffold the ovrtx code path and document the runtime requirement. Do not
substitute a browser renderer.
How To Use These Skills
When a user describes an Omniverse Realtime Viewer:
Route by user intent first.
Read
usd-viewer-app/README.mdfor broad viewer requests.Add focused references for requested capabilities.
Follow each selected reference's implementation notes and gotchas.
Capture validation and review evidence before considering the generated app ready to share.

NVIDIA dependencies: ovrtx, ovui, ovstream, and the ov-web-rtc browser client.
| Library | Install method | Notes |
|---|---|---|
ovrtx | See dependencies/nvidia-runtime.md | RTX USD renderer; RTX GPU required |
ovstream | See dependencies/nvidia-runtime.md | Streaming runtime |
ov-web-rtc client / @nvidia/ov-web-rtc | See dependencies/nvidia-runtime.md | Browser AppStreamer client for standalone ovstream Direct mode; do not use alternate package names, hard-coded client versions, or Kit/OVC/NVCF/GFN client connection profiles |
ovui | See dependencies/nvidia-runtime.md | Native UI toolkit |
ovui-data-adapters | Install from the same ovui package set | Local UI adapter contracts |
| Full editor UI package | Install only when current ovui dependency guidance explicitly requires it, from the same ovui package set | Full editor widgets |
ovstorage | Install with the selected project manifest or pip install ovstorage | Cloud asset browsing and cache sync |
ovphysx | pip install ovphysx -i https://pypi.nvidia.com | Physics simulation; check external skills |
cad2usd | External checkout | CAD file conversion to USD |
pxr / OpenUSD | pip install usd-core | Use version pins from platform skills |
numpy | pip install numpy | Array operations |
warp | pip install warp-lang | GPU kernels and CUDA buffer utilities |
Supplemental Guidance
Use the selected references as the implementation contract. When a dependency reference provides supplemental documentation, use it to clarify API behavior without changing the selected viewer architecture.
ovui guidance -> local UI package setup, widgets, overlays, and native UI conventions
ovstream guidance -> streaming runtime setup, SHM behavior, native input, lifecycle, and the ovstream repo's own skills/samples
ovrtx guidance -> renderer setup, Python/C API behavior, AOVs, picking, and selection
ovstorage guidance -> resolver and asset management patterns
Clone ovphysx -> check ovphysx/skills/ -> physics simulation, collider cooking, grab, drop
Clone cad2usd -> check cad2usd/skills/ -> CAD conversion and batch processingRequirements and compatibility

“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.
