VR-Forces Capabilities

Simulating Behavior

• Intelligence Models - A master scenario event list (MSEL) is used to present situational informa-

tion to the simulation operators. Events can be triggered by time, other event, or manually. Situa-

tional events can contain text, audio, images, or video. Events are available on the network and can

be sent to external role player systems.

• Communications Models - The communications model is used to send messages between simula-

tion objects, with options to model communication degradation by the network infrastructure.

Simulating Behavior

VR-Forces is a flexible framework for simulating objects and their interactions with the environment

and other simulation objects.

These behaviors give VR-Forces simulation objects a level of autonomy to react to the rest of the simu-

lation on their own. This saves you from having to script their behavior in detail. The autonomous

behaviors include:

• Using sensors to detect other simulation objects.

• Attacking enemy simulation objects on contact, based on the current rules of engagement.

• Sending and receiving spot reports through the simulated radio networks.

• Entity activity like “wander about” and “flee from something”.

• Identifying obstructions to movement and moving around them.

• Advanced navigation using Autodesk Gameware Navigation software.

Entities and Units

VR-Forces simulates at the entity level or the aggregate level depending on which simulation model set

(SMS) you use. Entities or units form the basic units of the simulation and are composed of models

that collectively represent units at all echelons, vehicles in all domains (air, land, sea, space), munitions,

cultural objects, and lifeforms.

The specific capabilities of entities and units are defined within entity definitions, which are organized

within Simulation Model Sets (SMSs). VR-Forces comes with two pre-defined simulation model sets:

an aggregate-level SMS, which defines aggregate-level simulation object models and an entity-level

SMS, which defines entity-level models (platforms, humans, and munitions).

Entities can function independently or collaboratively, such as:

• Embedding - This is the ability for a host entity to deploy other types of entities that it might typi-

cally carry. (Example: a ship that can deploy helicopters to dip sonobuoys.) Embedded entities

simplify the planning of scenarios by allowing users to ignore the embedded entities until that part

of the scenario where they need to be deployed. Compared to embarked entities, scenario devel-

opers do not have to create and embark the entities during scenario creation and the deployment

and recovery process can be automated. Embedded entities also increase network performance by

not sending out messages until they are deployed and independent of the host entity.

• Embarkation - Embarkation is the ability for one entity to embark on (or attach to) another

entity. Embarkation ensures that closely coupled entities, like a person driving a car, or the heli-

copter on the deck of a ship, or a missile loaded onto an airplane, all share a common frame of

reference.

Simulating Behavior

• Entity Aggregation - Different than aggregate-level simulation, entity aggregation is a way to

organize individual entities into echelon structures so that single commands can be carried out by

multiple entities. In addition, units can provide information about their echelon structure, loca-

tion, and health.

• Simulation Object Groups - Simulation object groups allow you to create a configuration of

simulation objects and tactical graphics that can be added to scenarios like individual simulation

objects. They are not tied to a terrain location, so they are available to any scenario. They can

include plans and scripted tasks, so that they are analogous to mini-scenarios that you drop into a

larger scenario.

Simulation Models

Simulation models define and implement the capabilities of the simulation objects within the simula-

tion. The specific configuration of a simulation object defines which models apply to that entity. Let’s

have a look at the models in VR-Forces.

Behavior - Movement

Movement models determine how simulation objects move through the simulated world.

• Dynamics Models - These are built into VR-Forces simulation objects that use an actu-

ator/controller paradigm to 'steer' through the virtual world. When you task a simulation object

to move, it's the dynamics model that defines how. See “Defining and Controlling Behavior,” on

page 17 for the various ways of tasking simulation objects.

• Mobility Models - Mobility Models affect, and usually limit, the capabilities of the dynamics

model defined for entities based on the conditions of the terrain and atmosphere. For example, a

ground vehicle's mobility is degraded when driving over mud, and stopped completely in deep

water.

• Hi-Fidelity Dynamics Models - VR-Forces comes with a full library of vehicle dynamics models

for air, land and sea. Some of MAK's customers develop higher-fidelity dynamics models for a

particular vehicle in their domain. You can develop your own dynamics models and use them

within VR-Forces. MAK also has partners who provide high fidelity dynamics models:

– RT Dynamics provides high fidelity rotor craft and fixed wing aircraft.

– CM Labs provides high-fidelity ground vehicle models.

• Animated Movement - A particularly high-fidelity way to move entities is to provide them a

predefined animation sequence to follow. This is an important technique for engineers who

develop extremely high-detailed engineering models of vehicles or munitions. Users of MATLAB

SimuLink can export the results of a dynamics simulation and use that animated sequence to

control the motion of an entity. This is useful for visually validating the engineering models and

for communicating the value of the models within an operational context.
