After long term carreer in 3D computer graphics since 1970 for the French Defense Nationale, where I designed the first 3D real time hardware system for flight simulators andn 3D design.
After I lauched the first 3D real time machines in France Telecom research Labs, for civil appilcation : Audiovisual, video-games, chroma-key, medical, architectural applications.

Now my main reserches are dedicated to Digital or Real PIPE organ,
I designed a brand new, low cost technology for the control of :

I'm a Doctor-Engineer from the University of Paris II Sorbonne Pantheon, And Engineer from ECOLE CENTRALE DE PARIS. After long term carreer in 3D computer graphics since 1970 for the French Defense Nationale, where I designed the first 3D real time hardware system for flight simulators andn 3D design. After I lauched the first 3D real time machines in France Telecom research Labs, for civil appilcation : Audiovisual, video-games, chroma-key, medical, architectural applications. Now my main reserches are dedicated to Digital or Real PIPE organ, I designed a brand new, low cost technology for the control of : - DIGITAL ORGANS - REAL PIPE ORGANS All my technology is described here : I introduced many brand new functionnalities in the PIPE ORGAN I built without any grant : - Polyphonic Expressivity, - Control of any register from any keyboard in 16' 8' 4' 2' Quint - Muti-organist can share a unique organ, and select any stops in parallel - Very low cost hardware design, suppressing complex wiring in many organs. - Undefinite number of "moves" from keyboards to physicl registers	METAPHYSICS and PHILOSOPHY Equivalcnce Energy-Matter-Information Sciences et philosophie : About informative complexity New mathematic theorem on degree n equations Neural Networks : the future of computer science Iteratives functions systems, biological models NUCLEAR PLANTS EXPLAINED NUCLEAR INDEPENDANCY Organ and civilisation Organ and sacred Liturgy Symbolique et ésotérisme de l'orgue
Thanks to this website, you will be able to : - Built a new digital organ - Refurbish an old one - Buit or refurbish a real new or old pipe organ My goal is primarily non-commercial open-source hardware and software. I have absolutely no link with any organbuilder nor organist in particular. My assocaiation is authorized to get gifts from particular people or organbuilders. I'm spenting my live in hardware and software developments for virtual and/or pipe organs I can help you in this noble goal.

My second passion is research, oriented to 2 domains : Virtual reality : the art of viewing and designing things which don't exist. Neural Network : In the heart of the du human brain, and more particularly the vision part of the brain. My third passion isdedicated to the study of the extraordinairy life of de my collatéral ancêtor : Jacques Donatien LERAY de Chaumont, financial surintendant of king Roi Louis XVI. Leray gave a 700000 Pounds to Lafayette, which helped him to fight against English army. And allowed Americans people to get Freedom and no longer be a UK colony !. He is recognized in the USA as "THE FATHER OF AMERICAN REVOULUTION"	La vie extraordinaire de mon ancètre collatéral Jacques Donatien LERAY de Chaumont Père de l'indépendance et de la création des USA
