Présentation

The Research Laboratory for Computer Graphics & Virtual/Augmented Reality (LIRV) of Polytechnique Montréal combines advanced skills in Virtual Reality, Augmented Reality, Scientific Visualization and, more generally, 3D Computer Graphics.

The research work of this laboratory takes place in virtual immersive environments such as the (CAVE) and several types of VR and AR headsets, coupled with high-performance graphics cards (GPU).

Students and researchers in this laboratory collaborate with researchers from different fields, locally and internationally: cyberpsychology, fluid mechanics, medical physics, biomedical engineering, automatic language processing, applied mathematics, human-machine interface, etc.

Expertise

Prof. Benoît Ozell's expertise lies in Scientific Visualization, Computer Graphics and Virtual Reality and Augmented Reality. His research activities focus on 3D Computer Graphics, Scientific Visualization and Virtual Collaborative Environments in immersion.

Professor Benoît Ozell is the director of the Research Laboratory for Computer Graphics & Virtual/Augmented Reality (LIRV) (www.polymtl.ca/rv/) at Polytechnique Montréal. He is an expert in 3D computer graphics, scientific visualization, virtual reality (VR), and augmented reality (AR). For the last thirty years, he has developed several software applications integrating numerical methods for the scientific visualization of physical phenomena. He has a very broad expertise in image processing and computer graphics which are key concepts in VR and AR technologies. For the past decade and more, the professor Ozell has been using GPU to increase the parallelism of software applications and has acquired considerable expertise with VR/AR and collaborative environments, in computer graphics and human-computer interaction (HCI) in immersive environments: Neurosurgery simulations on GPU with haptic feedback; Acceleration techniques for dose GPU calculation in radiotherapy and brachytherapy (now in commercial use); Augmented Reality for Training on Healthcare Simulators; Collaborative VR environment in a scoliotic spine surgery simulator in a CAVE Virtual Reality environment with the Sainte-Justine Hospital Centre; Various VR environments for clinical psychology in collaboration with the Radiation Oncology Department of the Centre hospitalier universitaire de Montréal (CHUM).
