Direct development and safety-critical certification of modern C++ in a embedded real-time operating system.

A project that originated at Spacetec IMC of Lowell, Massachusetts, as an application program interface for the SpaceBall game controller, which spun-off into its own startup, venturing into nascent virtual reality and online environments.Chief architect for a software engineering team that developed an original general-purpose motion-control application program interface and data exchange format for interactive applications such as simulations, games, education, and entertainment.• Established disciplined object-oriented analysis and design methods, incorporating use-case analysis and UML notation, using the Rational Rose design tool. • Prepared development schedules, C++ programming quality guidelines and conventions, and code-review procedures. • Designed and coordinated all aspects of the system architecture, implemented fixed-point transcendental functions, quaternion arithmetic, programmable math expression interface, and motion trajectory algorithms.

Investigated tools and techniques for automatically extracting 3D models from digital photographic imagery. • Working from imagery sources, constructed city building models used for an experimental web-based live reconnaissance exercise, integrating voice, digital imagery, VRML graphics, and communications. • Constructed visualization models engineering simulations of a reusable satellite launch vehicle, and a submergence vehicle. • Built a program to translate automatically any model imported by IRIS Performer into compilable C/OpenGL source code. Supported military C3I systems exercises.

At MITRE's Federally Funded Research and Development Center for Air Force C3 Systems, provided expertise in terrain modeling, image compression, graphics, visualization, visual simulation, virtual environments, and stereoscopic display technology.• Principal investigator on a MITRE-sponsored research project, which sought to transition "virtual reality" technology to a real-world application, namely a debriefing and review visualization environment for a computer-based battle simulation. Responsible for defining project objectives and coordinating project personnel.• Technical lead in a research project for the Air Force's Electronic Systems Center. The project investigated "virtual reality" technologies for command center applications. Responsible for developing a flexible multiprocessing software architecture, which can accommodate a variety of interactive devices, computer graphics, and displays, as well as software simulation capabilities.• Tested and evaluated digital image compression techniques, and defined a vector quantization algorithm for the display of digitized navigational charts. These techniques are now used as the standard for digitized map products across military services.• On a research project, and with follow-on support from Rome Laboratory, investigated three-dimensional graphics and display technologies for battle management. Examined the graphics capabilities of super graphic workstations with respect to the needs of three-dimensional terrain visualization. • Developed an algorithm for stereoscopic visual simulation of terrain scenes. Developed a unique algorithm for creating a polygonal model of a terrain surface based on sampled data. Designed and wrote the software for interactive terrain visualization.

As project technical lead, created the software architecture for a reservoir-engineering workstation for a major petroleum company. Responsible for the user interface management subsystem, including the menu management facility, menu description language, plotting and mapping facilities, and message interfaces. Established project quality standards for FORTRAN coding. On previous projects, led a software development team for an offshore drilling vessel simulator, designed display management and message facilities for an on-line remote drilling monitoring workstation, and developed displays and plotting software for a real-time drilling simulator. Major accomplishments included a 3D animated display for ocean vessel movement visualizations, a user interface dialogue scripting facility, a windowing system, real-time plot displays, on-line data structure editor, animated drilling rig subsystem displays, and a screen-oriented text editor.

Working at the (then) Naval Ocean Systems Center (now, Space and Naval Warfare Systems Center), developed programs for acoustical digital signal processing applications, in collaboration with research personnel. Wrote user's manuals accompanying the software programs. Major accomplishments included utility programs for fast Fourier transforms, correlations, filters, data extraction, and plotting. Used lex and yacc to construct a general-purpose program command interface tool.
