  • Enabled the customization of a virtual roller-coaster ride by developing seamless playback sequences, synchronized with control of a hardware motion platform.
  • Researched academic papers for cutting-edge computer graphics algorithms suitable for the implementation of the in-house 3D engine.
Technologies: MPEG, Glide, Direct3D, C++

VirtuoCity | A Multi-user Real-time 3D Platform

VirtuoCity is a system used as the base for projects in a wide range of application domains such as urban development, infrastructure, railway innovations, and airport terminals.

Users cooperate and communicate in real-time using 3D voice chat and virtual presence. The majority of the system was written in C++ with an embedded Python interpreter to add project-specific functionality. Clients run on Windows or OSX and server on Linux or Windows.

As an architect, I designed and developed the system, from scratch, including tooling to support content creators and 3D artists to easily create content for the platform. Leading the development team, I always delivered new platform functionalities required for projects on time and within budget.
