Rémi Arnaud is the Chief Technical Advisor at Cityzenith, and the mastermind behind 5D SMART City™. Rémi's involvement with real-time graphics started in the R&D department of Thomson Training & Simulation (now Thales) designing and then leading the Space Magic real-time visual system for training simulators, where he finalized his Ph.D 'La synthèse d'images en temps réel'. He then relocated to California to join Silicon Graphics's IRIS Performer team, working on advanced features such as calligraphic light points for training pilots. Later he co-founded Intrinsic Graphics where he co-designed the Alchemy engine, a middleware targeting cross platform game development for PS2, Xbox, GameCube and PC. Alchemy is still in use today as the core technology in games and 3D applications such as Google Earth. He was brought on as Graphics Architect at Sony Computer Entertainment US R&D, working on the PLAYSTATION®3 SDK graphics API, and joined the Khronos Group to create the COLLADA asset exchange standard, which is currently adopted by most 3D tools and applications such as 3dsMax, Maya, Photoshop, Sketchup, Unity, Flash, Mac OSX.
