VxSIM^TM is a novel multi-tier, open architecture visualization and simulation framework with
integrated cyber/physical features. It is available to run stand alone as a Modeling and Simulation tool for product design, engineering analysis, development, systems-in-the-loop testing, AI testing and much more, or as a plug-in to game engines such as Unity.

The tool suite includes:
Scene Builder – operator’s interface for selecting and configuring the simulation and scenario content
Stealth Viewer – client provides a non-interacting observer view of the simulation.
Scene Runner – server provides network communication infrastructure for receiving/sending data with client applications, agent and plugins.
Scene Controller – provides exercise initialization, event synchronization, simulation state control, time management and orchestration. This application can be run from a command line to support un-attended batch and Monte Carlo simulations. Supports real-time and non-real-time simulation for mixed fidelity analyses.
Controller & Run-time Data Viewer
    – Interface for vehicle model for remote control of vehicle and viewing internal dynamic state data, parameters and settings
    – Can be added to any agent
Debug viewers – support sensor model verification and validation.
SimNetData – data recording, scenario replay, analytics, metrics gathering, etc.
Various sensor models – Lidar, depth finder, GPS, EO, etc.
Vehicle Dynamic – integrates hydrodynamics and terramechanics with physics solver for accurate analysis in surf zone.
Wave Models – Surf zone wave models based on bathymetry, underwater obstructions, objects, vegetation, reef and wind conditions.

Unmanned Autonomy showcases VxSIM, Dynamic Dimension Technologies’ next-generation digital twin environment for developing and validating advanced autonomous behaviors in maritime systems. Designed to accelerate AUKUS and Indo-Pacific innovation, VxSIM enables defense and industry teams to simulate, test, and refine autonomy before field deployment—reducing risk, cost, and time to readiness.

The system integrates real-time physics-based boat dynamics, navigation stacks, and mission logic across distributed computers to replicate complex maritime conditions and communications constraints. As shown, VxSIM synchronizes remote vessel dynamics with local autonomy planning, allowing collaborative testing of unmanned surface and subsurface vehicles (USVs/UUVs) under dynamic ocean environments.

By supporting live-virtual-constructive experimentation, VxSIM provides a unified platform for human-machine teaming, evidential reasoning, and multi-vehicle coordination—enabling coalition partners to validate AI-driven control algorithms, adaptive routing, and mission resilience. Its open-architecture design supports integration with ROS/ROS2, autonomy toolchains, and national simulation frameworks.

Through VxSIM, partners across the AUKUS alliance and Indo-Pacific region gain a sovereign capability to safely advance next-generation autonomy, enhance maritime interoperability, and strengthen defense collaboration through digital twin–driven experimentation and validation.
