Hans was born and raised in the province of Zeeland in the Netherlands. When all the big waterworks around his home were finished and it was safe to take his finger out of the sea dike he went to the University of Twente for a masters degree in Computer Science. His thesis on Knowledge Based Human Grasping under the guidance of Michael Girard at SCAN in Groningen led to a paper in Siggraph 1991. After taking in the knowledge of his mentors he also took over their job and house and remained at SCAN for five years as head of R&D (working mainly on train simulators for the Dutch and European railways) and as a teacher of computer graphics and animation for a master’s degree programme.
In 1996 he came to Rhythm and Hues to start up the character rigging department. While writing new tools into R&H proprietary software for rigging purposes he moved into the software department where he is now responsible for a wide variety of topics related to character development, like character rigging and skinning, fur grooming and animation, model creation and deformation. Over the last 11 years he has worked on over 30 feature films like f.e. Mousehunt, Babe: Pig in the City, Harry Potter I, Cats and Dogs, Elf, Scooby Doo, Garfield, the Lion, the Witch and the Wardrobe, Night at the Museum, Evan Almighty and Golden Compass.
