Benjamin Legros is a Co-founder, chief scientific officer at Mercenaries Engineering at Mercenaries Engineering. He possess expertise in computer graphics, visual effects, computer animation, game development, opengl and 9 more skills. He is proficient in french. Colleagues describe him as "Benjamin have developed incredible tools during it's time in Nevrax. One of the most impressive is the PACS system. It's a collision data builder for manage collision with static objects and landscape on the MMO “The Saga of Ryzom”. This system is based on modelisation of the landscape by an ensemble of connected splines, with different altitudes for the 3d representation. Each spline represent a surface where is possible to a creature to walk, splines are connected to other spline arround and made a base for an A* algorithm for AI. This technology made possible to compute collides on server side with very accurate precision (around 1cm) without too many memory or processor usage (landscape of the world is bigger than 120km square, the world have more than 200k creatures walking on it) and made impossible to hake positions of characters from client side or any other position cheating."
