SimReady Foundation Sensors Tier

The simready-foundation-tier-sensors distribution contains the sensor capabilities, features, requirements, validator rules, and tier-owned Benchmark runtime tests for physics sensors, RTX LiDAR, and render products.

Install validation support:

pip install simready-validate simready-foundation-tier-sensors

Install the optional Benchmark framework and Kit engine dependencies needed to execute this tier's bundled runtime tests. This extra requires Python 3.12; validator-only tier installs also support Python 3.11.

pip install "simready-foundation-tier-sensors[benchmark]"

Contents

The tier owns the physics-sensors, LiDAR, and render-products capability groups, together with their features, validation rules, profiles, and runtime benchmark tests.

Capabilities

• physics_bodies/physics_sensors — PS.001 (IMU sensor placement) and PS.002 (joint sensor articulation root)
• nonvisual_sensors/lidar — LI.001–LI.004 (OmniLidar schema, emitter state length, scan rate, solid-state ray count)
• rendering/render_products — RP.001–RP.006 (RenderProduct wiring, RenderVar sourceName, semantic AOV compression)

Features

• FET_034_ISAAC — IMU Sensor (PS.001)
• FET_035_RTX — Camera and Render Products (RP.001–RP.006)
• FET_036_RTX — RTX Sensors (LI.001–LI.004)
• FET_037_ISAAC — Joint Sensor (PS.002)

The shared Hatch build hook generates simready/foundation/sensors/requirements/ from the capability Markdown and adds those enums to the wheel. Runtime-test documentation is colocated with the test package and assembled into the public Foundation guide from that single source.

Discovery

The wheel advertises two entry points:

• usd_validation_nvidia (simready-validate-sensors) -> simready.foundation.sensors:SimReadyPlugin lets the validator discover rules and requirements.
• simready.tier (sensors) -> simready.foundation.sensors:tier lets validation and Benchmark discover the tier's requirement module, catalogs, profile sources, and optional runtime-test package.

Build

From the repository root:

./repo.sh build_tiers

On Windows use repo.bat build_tiers. Wheels are written to nv_core/tiers/_build/dist/.

See simready_benchmark_kit_suite/docs/authoring.md for runtime-test authoring.
