The Quantum3D GeoScapeSE™ library of synthetic
environments (SE) for use in OTW (Out-the-Window), NVG (Night
Vision Goggle), IR (Infra-Red), EO (Electro-Optical), and Radar
realtime simulation and training applications has been optimized
for use on Quantum3D IG Solutions. Drawing upon Quantum3D’s
collection of common source materials including orthorectified,
co-registered, color balanced geospecific imagery; USGS Level
I DTED elevation data; and precision-modeled (to FAA Level D standards)
high-resolution AOI (Area Of Interest) military and civilian airfields
and training areas results in a unique, commercial-off-the-shelf,
low-cost yet high-fidelity synthetic environment database solution
for standalone or correlated OTW and multi-spectral sensor simulation
mission rehearsal and training applications such as Fixed Wing,
Rotorcraft, Ground Vehicle, Homeland Defense, First Responder,
Dismounted Infantry, and Rail Engineering.
 Developed
with the same 3rd party and Quantum3D tools and COTS workflow
methodology as used in Quantum3D’s CatalystSE™ Database
Generation System, OTW terrain databases are built and output
in OpenFlight™ form using Terrex® TerraVista™ ProBuilder,
the most widely-used COTS tool for creating terrain databases.
AOIs, airfields and target/training area models are built using
MultiGen-Paradigm® Creator™, the Vis-Sim industry’s
leading tool for creating, modifying, and optimizing OpenFlight
models. The completed project is processed by Celerity™,
Quantum3D’s COTS database publisher/formatter tool for final
output in binary form optimized for use on Quantum3D IG Solutions
that feature the Mantis™ Realtime Scene Management Software
Suite.
Celerity optimizes the database for 60 Hz operation
by streamlining and consolidating database hierarchies and inserting
up to eight LODs (Levels-Of-Detail) within the database to minimize
scene loading. Celerity publishes for “round earth”
applications using the WGS-84 datums. UTM, Lambert Conic Conformal
(LCC), and Flat Earth are also available. Meta data is inserted
to support efficient paging and Quantum3D START™ (Scene Transition
Artifact Reduction Technology), which virtually eliminates artifacts
associated with LOD transitions without performance impacts and
unwanted correlation side-effects. Celerity also produces wide-area
material classification for sensor simulation applications, and
formats the database output in Mantis Native Paging (MNP) for
use on Quantum3D IG Solutions.
 Sensor
simulation (material classified) databases for NVG, IR, EO, and
Radar applications are precisely correlated with the corresponding
GeoScapeSE OTW synthetic environments. Each database uses the
same terrain and model files, and the required material classified
maps are generated from corresponding OTW terrain and model textures
using COTS tools including Surface Optics™ ImageMapper and
Material Library, along with the wide-area terrain material classifier
that is included in Celerity. OTW and model textures are material
classified at the texel level using a sophisticated, weighted
three-material system for NVG, IR, and EO sensor simulation applications.
Radar databases are generated by conversion of corresponding OTW
OpenFlight database into equivalent rendering format for radar
application processing and display. The net result is a high-fidelity
material-classified database, ready for deployment on Independence
ER IGs equipped with sensor simulation channels.
GeoScapeSE databases output formats include
OpenFlight for input to other database conversion tools, DTED
for input to SemiAutomated Forces and Computer Generated Forces
applications, and Quantum3D’s optimized runtime format for
60 Hz applications, MNP (Mantis Native Paging).
GeoScapeSE databases take full advantage of Quantum3D’s Independence
IG Solutions, including the Mantis Realtime Scene Management Software
suite of applications that render terrain, models, weather, and
special effects in conjunction with the SE database. Mantis monitors
simulation system conditions, retrieves necessary database content
from disk or network storage subsystem using database meta data,
determines the appropriate LOD database content to be rendered,
and directs IG subsystems how to process LODs, including START™,
host-directed model scaling and Mantis Continuous Model Scaling
for enhanced object recognition.
State-of-the-Art shader-based rendering techniques
are employed in many Mantis plug-in options and extensions, including
Advanced Marine Effects, Advanced Weather Effects, Rotor Wash
Effects, Realtime Shadow Simulation, Realtime Foliage Simulation,
Human Entity Simulation, and viXsen Sensor Simulation, to provide
levels of visual realism and accurate training cues that have
not previously been available on IGs running at 60Hz frame rates.
Quantum3D’s Advanced Marine Effects option
creates comprehensive, realistic open water and shoreline behavior
and appearance in the database and includes host-controllable
sea state and environment settings, and inter-channel synchronization
to ensure correlation across multiple channels and multiple channel
types including OTW and Sensor Simulation channels. Shader-based
effects include bow and stern wakes; Gerstner wave functions for
generating ocean geometry; seamless blending between 3D polygonal
ocean waves close to the view point and distant 2D bump map ocean
waves; animated whitecaps with wave crest spray; reflection of
actual scene for low sea states; bump mapping applied to diffuse
lighting and environment reflection using animated ripple texture;
and animated breaking waves with a gradual blend to sand color
at shoreline.
Advanced Weather Effects includes shader-based
3D clouds and storm fronts that are host-controllable in height,
thickness, geographic extent, density, percent coverage, shading,
edge brightening, and respond to lightning bolt flashes. Other
Weather Effects include 2D cloud layers, atmospheric fog, haze,
rain, snow, and wind. 3D clouds incorporate illumination from
ambient light sources and provide accurate occlusion of objects
within the scene. Material classified versions of effects are
available for sensor simulation applications.
Realtime Shadow Simulation supports up to eight
(8) moving model entities that may be selected under host control
as shadow casters. Terrain may be user-selected or deselected
as a shadow receiver. Shadows are correctly projected on terrain
or model entities, based on sun angle, eyepoint position, shadowed
object orientation, and with realistic shadow fade as distance
between shadowing and shadowed objects increases. On select Independence
models, terrain and cultural feature shadowing are also available—including
NVG shadows.
A comprehensive set of Special Effects includes
debris, tracers, missile trails, flames/explosions, particles/sparks,
cluster effects, illumination flares, and animations. Mantis also
provides continuous time of day, which includes a validated ephemeris
model with sky model, sun, moon, planets and over 9000 stars in
the star field. SE database airfield and landing system lighting,
including VASI, PAPI, GAIL, PLASI, FLOLS, IFLOLS and REIL are
controlled by Mantis or through Host interface directives. Mantis
interrogates the database to perform host computer requests for
mission function calculations, including Height Above Terrain,
Height Over Terrain, Line Of Sight, and Collision Detection. Mantis
controls 3D models in database scenes and Quantum3D’s Facets
COTS Realtime 3D Model Library includes approximately 900 high
quality realtime 3D models, with multiple LODs and highly realistic
tri-resolution textures optimized for use with GeoScapeSE database
applications. Facets models are available separately in OpenFlight
format, and where applicable, come equipped with multiple paint
schemes, a synthetic infrared (IR) sensor simulation scheme, damaged/destroyed
states, articulated parts, and animations.
 Using
the CatalaystSE DBGS process, OTW and model textures are material
classified to the texel level for NVG, IR, and EO sensor simulation
applications using the three-material scheme described above,
so that terrain geometry and model geometry are common between
the material classified and OTW databases. Radar databases are
generated by conversion of a corresponding OTW OpenFlight database
into an equivalent rendering format for radar application processing
and display.
Material classified databases combined with
a Quantum3D Independence ER Sensor Simulation Solution (IS3) Channel,
which includes the viXsen Physics-Based Sensor Simulation plug-in
to Mantis, is an integrated solution that simulates advanced passive
sensors using real-time pixel-based computations, which allow
for accurate temperature, lighting, and scattering computations
in the simulation and for accurate modeling of a true sensor display.
The material classified database solution is physics-based and
fully correlated with the OTW database. Sensor simulation and
environmental parameters are easily modified via host-control
or IG control during run-time and the material classified database
incorporates a radiometrically-correct realtime 3D atmospheric
model using MODTRAN4 based on JRM Technologies SigSim™. Quantum3D
IGs equipped with NV40GL or later GPUs support shader-based per-texel
lighting and calculation of scene in-band response values on a
per-pixel basis. Use of material mixture maps with up to three
materials per texel with percentage weighting between materials
and advanced thermal calculations using a one dimensional heat
transfer algorithm enhance the accuracy of the material classified
database and a single material texture can support EO, IR and
NVG sensor simulations.
Advanced support for NVG simulation includes
horizon glow tied to moon elevation and phase, city glow displayed
on horizon caused by distant urban areas, light point halo model
incorporating atmospherics and light power level data, support
for OTW special effects such as flame, explosion, air explosion,
tracer, flash, rotor wash, and missile trail effects, Mantis OTW
correlated star field support, detail texture support for terrains
and models, cloud layer simulation correlating to OTW view, static
shadow support in material code textures, and dynamic terrain
self-shadowing (available on select Independence ER models.
