François Lehericey, Ph.D.

I am a doctor in computer science and specialized in virtual reality. I currently work for Vinci construction on building information modeling. My subjects of interest include physics simulation on which I worked on during my Ph.D. (see publications)

This video show some example of simulations with cloths that use the method provided by the paper “GPU Ray-Traced Collision Detection for Cloth Simulation”. Collision detection is performed with ray-tracing and an inversion handling method correct error due to discrete simulations.


This video show examples of simulations that use IRTCD for collision detection. IRTCD (Iterative Ray-Traced Collision Detection) is a novel method that exploits spatial and temporal coherency. This video shows how our iterative method improve performances.
