Virtual Reality

Nowadays, virtual reality (VR) is no longer limited to a projection of synthetic 3D content (aka OpenGL = Open Graphics Library, cf. 3D games) in a stereoscopic head mounted display. Indeed, the future of VR lies rather in the holographic projection of real/natural content, previously captured by conventional cameras (360 video) possibly augmented with depth estimation or sensing in order to obtain a totally immersive video at 6 Degrees of Freedom (6DoF). Theoretical concepts like the 3D graphics pipeline on a GPU (Graphical Processing Unit) with its camera, projection and lighting models, as well as 3D capture and rendering technology will be presented.

The student will learn the main aspects of OpenGL/WebGL (practical part), as well as multi-camera capture and rendering methods in immersive 6DoF video (theoretical part) which are partially based on concepts of OpenGL.

Required and Corequired knowledge and skills

C/C++ programming skills are strongly recommended (medium level).

The exercises will help the student to develop a 3D game in OpenGL/WebGL with shaders in GLSL (Graphics Library Shader Language), while the theory will give the student all the skills required to understand a scientific article on immersive video in depth.

Contribution to the teaching profile

3D next-generation capturing and rendering techniques for multimedia engineers.

Method(s) of evaluation

• Project
• Oral examination

Project

Oral examination

OpenGL/WebGL project + open book exam for the theoretical part (6DoF immersive video, mainly).

Mark calculation method (including weighting of intermediary marks)

The score is built for 50% on the OpenGL/WebGL project, and for 50% on the theoretical exam (open book) where the student will have to present a scientific concept covered by one of the chapters and/or scientific articles presented (sometimes only partially) during the theoretical sessions of the course.
