What are First Responders?
They are the policemen, firemen, EMTs, public
works officials, and HAZMAT teams who answer the
call when disaster strikes. They give aid,
mitigate circumstances, assess damage and contain
the danger.

Training First Responders
Training events staged in urban settings can
quickly become media spectacles.
and public relation nightmares.

Training in Virtual Environments.Military Style
Objects Persist and change state (position,
velocity, and damage).
Weather is governed by nature
Interactions Transient activity of finite
duration like attacks.
Radar supplies sensory information
Sensors supply information regarding spread of
chemical agent
Terrain information is static and shared
throughout a simulation
Chemical attacks are man-made objects that are
governed by the laws of nature

Some Common Themes

• Realistic training vignettes
• Safe and secure environments
• Analysis and evaluation tools for trainers
• Compatibility with existing simulation systems
  via High Level Architecture compliancy

9
Creating Order amid Chaos

• Apply formal software engineering practices to a
  scientific simulation/virtual reality project
• Use the Rational Unified Process for creating the
  system architecture
• Incorporate scientific object-oriented software
  into a real-time training environment

Use Case View
The Unified Modeling Language representations

• A use case specifies a sequence of actions,
  including variants, that the system can perform
  and that yields an observable result of value to
  a customer (called actor).
• System attributes and functions combine to form a
  use case.

HLA Terminology
Implementation View

• A Federate is a stand alone simulation. HLA has
  no requirements on the design of the Federate
  other than it provide a predefined interface.
• A Federation is a collection of Federates. It is
  a distributed simulation involving the Federates
  communicated in a prescribed manner. HLA is a set
  of rules governing the form and method of
  communication between the Federates.
• A Federation Ambassador is the interface (or set
  of operations (functions)) the Federate is
  required to provide in order to participate in
  the Federation.
• The Run Time Infrastructure Infrastructure (RTI)
  is the central controller (server) that manages
  the communications between the Federates
  (clients). It is a set of prescribed functions
  that passes all information between the
  Federates. It is Federation independent.
• The Federation Object Model is a description of
  the information passed between the Federates that
  is managed by the RTI. It is Federation specific.

Gas Model - Numerics
Design View
Cell
The control volume approach divides the room into
cells. At each time step and for each cell, the
controller calculates the forces on each face to
determine the flow of the various chemical
species into and out of the cell. This results
in updating the concentration attribute (a set of
numbers corresponding to each species), the total
energy with the cell, and the flow (velocity)
across each edge.

Structure Model
Design View
Imagine a toxic gas being released in your
average office building. The gas molecules will
go wherever they are allowed to go. The
interconnections between rooms, halls, and floors
is terribly complex.
This is a tool developed in VEnOM called MapMaker.
33
Structure Model - UML
Design View
This is a simple model showing the composition of
a building structure object.
34
Structure Model
Design View
Using MapMaker we can take a blueprint, draw the
structure model, and export to two file types.
One is a 3D model called map files. The other is
instantiates our structure model.
This is a 3D modeling tool called Valve. It was
used to build the model used with Half-Life.
35
Graphics Engine
A graphics engine manages the position and
orientation of many objects in a virtual
environment. It adjusts camera perspective,
determines collisions, and runs animations.
What you will see today using the engine within a
computer game called Half-Life. Everything was
developed as a modification to the original.
Special functions were incorporated using the
associated SDK.
