Key member working on free-viewpoint video product, using stereo reconstruction. Helped architect and worked on nearly all aspects (processing pipeline, background subtraction, mesh reconstruction, texture reconstruction, texture and mesh compression, and playback engine) of the product. Overview of the system was published in SIGGraph 2015.See paper for details:http://causticpixel.com/papers/fvv.pdf

Lead Graphics Developer on Forza 3 (XBox 360 Game). Lead team of 12 developers responsible for building the graphics engine and low level systems.

Individual contributor on rendering engine team for Forza 2 (XBox 360 Game). Implemented export and runtime rendering of cars. Included morph target support, improved damage model, scene management, LOD support, precomputed radiance transfer (PRT) for car rendering, and initial implementation of animation support.

Development lead on Windows Presentation Foundation (WPF). Lead team of 4 developers in disparate areas. Individual contributor for Bitmap Effects

Was Lead Graphics developer for unshipped title (NFL Fever 2006 for XBox 360). Lead team that rewrote the rendering engine.Individual contributor on rendering engine team for NFL Fever 2004 (XBox title). Development lead for 3 developers working in different areas (UI, Audio, and Graphics)

Development lead responsible for team of 3 developers for the Media Library Services feature in Windows Media Player (Win32 version)Development Lead for 3 developers delivering Windows Media Player for the Mac, Unix, and WinCE versions.Individual contribute on Windows Media Player (Win32 version)

Individual contribute on ChromeEffects Editor (unshipped product that integrated 3D rendering into Internet Explorer)

• Sole developer of Marvel, a VRML97-based modeling package. Editor supported display,creation, and editing of VRML nodes. Application developed using MFC. • Sole developer of Picasso, a photo touchup and painting application. Supported various image filters (sharpening, blurring, motion blur, ...). Supported image transformations and region editing. Included various paint tools and image adjustment filters (e.g. contrast/brightness, gamma correction histogram equalization, etc)

• Major contributor in developing MetaLinkThis package is a 2D CGM-based graphics package for authoring Interactive Electronic Technical Manuals (IETMs). Responsibilities included development of image transformation, display, and editing routines, MPEG video support, scripting language support, automatic shrink wrapping, device independent drawing and event handling, and various other portions of the product.

• Primary developer of Noise-Power Spectrum program (GRAIN)This program is used for calculating the Noise-Power spectrum for a given microdensitometer scan of film. The principal users of this program are the scientists within the research laboratories. This program was written exclusively in C++ and Motif.• Key contributor to core librariesThe GRAIN program described above makes extensive use of graphic libraries used by the development group. Myself and one other engineer were the primary developers of these libraries. These included math, statistics, imaging, Fourier transform, and plotting libraries.• Maintainer of development environment

• Principal member of team which developed a PostScript Level II compatible interpreterOur team developed a complete PostScript Level II interpreter. This interpreter was completed in a timely fashion and passed a formal QA process (which entailed passing the Genoa test suite). My responsibilities included development of the halftoning algorithms, path rasterization, and other miscellaneous aspects of the PostScript interpreter’s rendering layer.• Major contributor on team that designed and developed Kodak’s Coloredge Desktop Composition System.This system included a full WYSIWIG graphics editor. Responsible for developing such features as cubic curve fitting, raster to vector conversion, user interface, and general 2D object manipulation and rasterization.• Primary developer of a full-color image editing/retouch applicationThis package included arbitrary shaped brushes, realistic painting effects, image warping, keyboard macros and plug-in filters via a built-in extension language, color dithering, arbitrary transformations, and various other image processing effects. Designed a device independent drawing library which supported a window-like hierarchy with arbitrary clipping, and a window system independent interface library.• Designed and implemented a print server used for Kodak’s Kodiak printerThis was a product probe to a limited number of customers for Kodak’s XL7700 printer. Responsible for developing MacIntosh chooser driver and print server daemon and scheduler for Sun SPARCstation.• Played integral part in developing core librariesAll of the applications listed above, and various other miscellaneous applications were built atop of code libraries developed by our group. My responsibilities included developing, maintaining and enhancing these libraries. These include image manipulation, general data structures, 2D rasterization, window-system abstractions, and device-independent drawing libraries.
