Dynamic Dimension Technologies is proud to be teamed with LSI and BAE Systems to develop and deliver the prototype Surf Zone Driver Trainer System.

DDT's role on the team was to add our real physics models for the Ocean, Surf Zone and Vehicle Dynamics. Integrating our real physics models brings a monumental level of realism to the VR world.
Training with realistic vehicle responses on land, ocean and especially in the surf zone, makes all the difference with mission preparedness.

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.
