Designed to support correlated, open-architecture environments, the Tool Set enables database developers to material classify OpenFlight™ OTW databases, cultural features, and moving models and format them for runtime use with Quantum3D IS3 Channels . The Tool Set includes a Material Classification Tool, a Material Preparation Tool, a Materials Library, and Celerity™, Quantum3D’s database optimization tool that produces highly optimized, pageable runtime binary formatted databases with OTW, RADAR, and material classified textures.

The CatalystSE 2500 ER DBGS Material Classified Database Development Tool Set option has been designed to enable R&D organizations and training systems integrators to develop material classified textures from visual databases to provide correlated sensor simulation channels and is comprised of the following components:
- Quantum3D and Third Party Material Classification Tools and Material Library Software are used to convert textures in a visual or Out-the-Window (OTW) database to material classified texture “systems” suitable for realtime physics-based rendering with dynamic heat transfer, time of day, and radiometrically correct atmospheric propagation, for high-fidelity at-aperture results.
- Quantum3D Celerity™ Database Optimization Tool Suite for optimizing wide-area OTW and material classified databases, which enables the output of industry-standard third party COTS database generation tools to take full advantage of the advanced graphics technology present in Independence Visual and Sensor Simulation IGs.
- Sensor Post Processing Effects API and SDK for tuning sensor post processing parameters such as noise, scintillation, gain and offset levels, AGC, blur, and AC coupling to match real world sensor characteristics.
- Reticle/Symbology Programming APIs are used to add reticle and/or symbology overlays to IS3 Channels using Quantum3D’s IData™ Human Machine Interface (HMI) tool or OpenGL® directives.
Note: CatalystSE 2500 ER contains technology that is subject to U.S. Export Control and which requires authorization by the U.S. Government for export to foreign countries. CatalystSE 2500 ER products may not be transferred, transshipped on a non-continuous voyage, or otherwise be disposed of in any country, either in their original form or after being incorporated into other end-items, without the prior written approval of the U.S. Department of State.

Using the Tool Set and starting from the OTW database, developers can easily craft a set of textures that are optimized for use with IS3 Channels which employ, physics-based, end-to-end simulation using per-texel calculations to provide highly realistic simulated sensor displays and mission functions in realtime, taking into account scene dynamics, including diurnal loading/unloading cycles, energy absorption and transfer across boundary layers in a material system, energy reflection, and radiation of internally-generated energy such as that from a combustion engine. Furthermore, transmission losses dependent on slant range and environmental characteristics are modeled from the radiance point to the sensor aperture viewing location.
 A key component of the Material Classified Database Development Tool Set is ImageMapper™ and the associated Master Materials Library from Surface Optics Corporation, along with Quantum3D’s batch-classifier for large area terrain classification. Together, these tools enable developers to transform visual texture maps on terrain, cultural features, and moving models within a database into material classified textures. The viXsen realtime rendering software in IS3 Channels employs this material information to render a spatially variant radiance image in realtime. Using the Material Classification Tool, database developers can choose from three material classification algorithms, assign up to three materials per texel, classify sub-regions of the texture, and model heat sources purely through textures.
The Material Library contains reflectance, emittance, and thermal data for a wide set of materials that are common to simulation and training applications. In addition, developers may easily add their own materials to the Materials Library, or use existing materials within the library to create unique material systems for their application. Since material classified databases are built from the OTW textures by assigning material systems to visual textures, correlation with the OTW database and to a Correlated Terrain Database (CTDB) for Semi-Automated Force (SAF) application is achievable – to the texel level. Correlation with elements in the scene including terrain, models, and culture among sensor simulation and out-the-window channels is inherent and precise, avoiding the correlation problems typically found in other sensor simulation solutions.
 Celerity produces highly optimized, pageable runtime binary formatted OTW, RADAR, and material classified databases. Once the visual texture maps are converted to material classified texture maps within an OpenFlight database, Celerity is employed to produce a highly optimized binary runtime version of the database that is suitable for realtime rendering. Celerity eliminates inefficient hierarchy within a database and performs visual or material classified texture compression and other critical steps to enhance runtime performance, which is essential in large area databases requiring paging at 30 or 60 Hz (or higher). Celerity is used for OTW, material classified, and RADAR databases, which ensures correlation and is included with all Independence IGs.
Simulated sensor effect parameters, including noise, scintillation, AC coupling, manual gain and level ranges, AGC thresholds, and polarity may be tailored to match specific sensor parameters using the Sensor Effects API, which provides a broad set of capabilities to address a wide range of real world sensors and is included with the purchase of IS3 Channels. Once the sensor post processing parameters are established via the API, they may be stored in a Channel Configuration File in the IG Controller that is associated with the given channel. These are then loaded at initialization time. Runtime control of the sensor effect is via CIGI host packet or IGM user interface. Customers with unique parameter requirements should contact Quantum3D for custom programming options or they may opt to purchase the SDK, which provides developers with the “hooks” to customize programming of the unit.
Quantum3D IData™ and IData plug-in for Mantis provide a highly intuitive human / machine interface development tool for the creation of Reticle / Symbology databases, as well as the realtime rendering of same in the target environment.
The Independence 2500 ER IS3-141 Sensor Simulation Channel option enables cost-effective development and validation of material classified databases on DBGS without impacting limited simulator resources. The IS3-141 channel includes a 1U single IG Rendering Unit server-class PC with NVIDIA® QuadroFX® 4000 Graphics and Quantum3D Mantis and viXsen Software with JRM Technologies’ SigSim™ with MODTRAN4 atmospherics for 8/16-bpcc monochrome “at-aperture” rendering with per-texel, physics-based calculations on material classified textures, and a CC3-QST Channel Compositor with post processor sensor effects, including blur, A/C coupling, gain, level, offset and other effects as they would appear deployed on an IDX 2500 ER IG equipped with an IS3 sensor simulation channel.
