Feature: FET_035_RTX

Property	Value
Feature Name	FET_035_RTX
Runtime	ISAAC
Proprietary Techs	None
Latest Version	0.1.0

Description

Defines the simulation-readiness contract for the USD render pipeline wiring on assets used in synthetic data generation (SDG) and software-in-the-loop (SIL) workflows. Every RenderProduct prim must have a valid camera relationship and at least one AOV declared via orderedVars. Each RenderVar must declare a valid sourceName. Semantic AOV RenderVars must use BLOSC lossless compression to preserve integer segmentation labels.

RenderProduct and RenderVar rules apply to all sensor types including cameras and LiDAR — they are render pipeline infrastructure, not sensor-specific. The capability lives under rendering/render_products/ rather than under any sensor modality directory.

Dependency Graph

This feature has no dependencies and no other features depend on it directly.

Use Cases

Products or workflows that consume this feature:

• SimReady validation verifies render product wiring requirements at asset authoring time.

• Isaac Sim Replicator SDG pipelines consume render products to generate annotated training data.

• Isaac Sim runtime benchmark tests (render_product_output, semantic_aov_output) verify live annotator output.

Benchmarks

• render_product_output — verifies structural RenderProduct wiring and that each annotator returns non-empty output via Replicator.

• semantic_aov_output — verifies BLOSC compression is authored and semantic annotators return non-empty arrays.

Adapters

• _fix_compression (RP.004 Suggestion) — sets srtx:compression:type = "blosc" on semantic AOV RenderVars.
