Technical interest is in graphics rendering (3D engines, scene graphs). Have done OSG programming professionally at flight simulation and ROV companies, and game/graphics programming at Electronic Arts.
Latest work experience has been to improve the graphics of older software (1990s era) up to the modern level of shader-based graphics ("Ooh-ahh, it looks awesome now!").
