Marc Le Renard

I am graduated from the french engineering school ESIEA. I was involved since 2001 in various Virtual Reality projects (european, national, research or industrial projects). I acquired many skills in the VR and AR fields. I love sharing my expertise and teaching about these areas.

I founded FOKS lab in 2017 to be freelance. Learning and creating innovating solutions, easy to deploy and to maintain, is what motivates me.


Since its creation, FOKS lab was involved on various projects : consultancy, development, teaching, industral projects, museography, ...

Other contributions

I am also involved in artistic creation to develop installations in partnership with artists & designers

#Hashedtime is an artisitc work which presents simultaneously the most popular hashtags from Twitter creation (2006) to nowadays. Instagram best photos are presented too from 2010 to nowadays. This is a dynamic piece which updates all the time to display the topics covered on social networks over time.

Posting on forums or through discussions with developers / writters I share my expertise to improve the tools or to give pertinent feedbacks in order to help the VR community.
Fluid engine development - Doyub Kim / CRC Press (ISBN : 978-1-4987-7992-6)

Really well written book to learn about fluid simulation (from theory to implementation using C++). This book is a good basis for who wants to develop a simple fluid simulation engine. I used it to illustrate some optimisation concepts when teaching physic simulation.
