Python: Status Queries Example#

This example is based on the minimal Python example and adds operation status queries for USD loading and rendering.

It demonstrates:

  1. Loading a USD layer with open_usd_async()

  2. Polling Operation.query_status() while waiting

  3. Running one shader-cache warm-up step with shader compilation progress

  4. Stepping the renderer with step_async()

  5. Fetching and mapping the rendered output

Renderer logs are written to _output/status-queries-ovrtx.log.

“Create a Python rendering example that demonstrates progress reporting for long-running ovrtx operations, including asynchronous scene loading, status polling while waiting, shader warmup feedback, final frame rendering, and save-or-display output.”

Prerequisites#

  • Python 3.10-3.13

  • uv

Running#

uv run main.py

To save the render instead of displaying it:

uv run main.py --png
