Gaël Sourimant

Senior Engineer

Home Experience Lab Researchers

I graduated and received a MS in computer science from Rennes 1 University in 2004, followed by a PhD at the INRIA on 3D reconstruction of urban areas using GPS, GIS and uncalibrated video data, which I defended by the end of 2007. After two years as an expert engineer at INRIA working on 3D reconstruction and rendering for auto-stereoscopic 3DTV, I joined Technicolor in March 2010.

My scientific interests since then focus on real-time CGI rendering, targeting especially high-performance graphics and visual fidelity for VFX. In the past years I worked on a wide variety of graphics contexts, from CGI and VR on set-top-boxes to high-end workstations for accurate lighting simulations in VFX studios. In all cases I worked both on the development of innovative solutions, and the associated software architecture.

Since 2015, I'm a member of Technicolor's Fellowship network.

Research interests:

Almost everything that falls into the fields of image synthesis and processing

  • Lighting simulations
  • Monte-Carlo rendering
  • Rendering engines
  • Images post-processing
  • Virtual Reality rendering
