stepping-and-rendering

To step the renderer in ovrtx, load your USD scene, initialize the renderer, and call step with a delta time. This advances the simulation and generates deterministic camera and sensor outputs frame by frame.

Yes, you can use ovrtx stepping to simulate sensors for USD scene debugging. The stepping mechanism integrates sensor simulation into USD-based workflows, advancing the renderer to collect and read back generated sensor data.

To generate deterministic rendered frames from USD scenes, you need a functioning ovrtx checkout with USD scenes and a properly initialized renderer. Calling step with a delta time ensures deterministic frame production.

You read back rendered images from ovrtx after a step. By calling step with a delta time, the renderer advances the simulation, generates the camera and sensor outputs, and makes the images available for read back.

Use frame-by-frame stepping instead of continuous rendering for workflows that require deterministic frame production, such as sensor data generation, simulation debugging, and test rendering of USD scenes.

Ovrtx rendered frames may lack determinism if the renderer is not properly initialized or if the USD scene is not loaded correctly. Ensure your ovrtx checkout is functioning and the renderer is initialized before stepping.
