Release Notes#

5.0.0#

General#

  • Updated to Kit 107.3.1

  • Open Sourced codebase with Apache 2.0 license at isaac-sim/IsaacSim

  • Isaac Sim Core Experimental API: a rewritten implementation of the current Isaac Sim’s Core API designed to be more robust, flexible, and powerful, yet still maintain the core utilities and wrapper concepts.

  • Support for Neural (NuRec) Rendering

PhysX#

  • Actuator Model Update

    • PhysX in IsaacSim supports improved joint friction and actuation models:

      • Joint friction can now be configured similar to a Stribeck friction model. See the friction-related attributes in the new PhysxJointAxisAPI

      • The new PhysxDrivePerformanceEnvelopeAPI allows modeling speed-dependent torque limits in order to capture electric motor performance envelopes.

  • Deformables Beta

    • PhysX supports a new schema for volume and surface deformables, replacing current particle cloth and deformable body functionality. The beta feature set can be enabled in the physics preferences:

      • Edit → Preferences → Physics → General → Enable Deformable Schema Beta (Requires Restart)

  • Spline-Based Conveyance using Surface Velocity API

    • Added PhysxSplinesSurfaceVelocityAPI schema that allows the surface velocity to follow a path based on a given UsdGeomBasisCurves

Synthetic Data Generation#

  • Perception Data Generation (Replicator)

    • Added example snippet using Replicator’s CosmosWriter to output data in a format specific for the NVIDIA Cosmos Foundation Models

    • Added example snippet for searching and loading SimReady assets for SDG using the Simready Explorer

  • Action and Event Data Generation

    • New anomaly event extension (isaacsim.replicator.incident) creates box topple, fire, and fluid spill events

    • New robot animation extension (isaacsim.anim.robot) controls AMRs through animations

    • New scene captioning extension (isaacsim.replicator.caption) produces natural language descriptions of the 2D scenes as well as 3D spatial graphs of assets on the stage

    • New camera placement and calibration extension (isaacsim.sensors.rtx.placement) optimally positions cameras based on scene layout and coverage requirements

    • Updated the actor SDG extension (isaacsim.replicator.agent)

      • New custom command template

      • NavMesh Area integration

      • Built-in RTSP Writer

      • UI Improvements

    • Updated the object SDG extension (isaacsim.replicator.object)

      • Added embedded interface, enabling the user to preview the populated scene before capturing data.

      • UI improvements, adding a distribution visualizer to visualize xformOp ranges.

      • Performance improvements, parallelizing I/O to improve generation speed.

      • New examples are added to demonstrate randomization dependency.

    • New light weight Kit application, based on Isaac Sim App Template, deploys efficiently in both GUI and headless modes

  • Grasping Synthetic Data Generation

    • Added a physics-based grasping dataset generation workflow that generates and evaluates grasp poses.
