Pierre Bezier was best known for popularizing Bezier curves
used in CAD and computer graphics systems.
These curves are used to design objects like automobile bodies. Fonts like TrueType and PostScript were
designed using Bezier curves.
Bezier came from a family of engineers. He followed in their footsteps and earned
degrees in mechanical and electrical engineering from French universities. At the age of 67 he earned a doctorate in mathematics.
Work at Renault
For 42 years Bezier worked at Renault as a tool setter, tool
designer, head of the tool design office, director of production engineering,
and director of the machine tool division.
At Renault, Bezier was responsible for most of the mechanical parts for
the Renault 4CV.
Even being a prisoner of war in Germany during WWII did not
stop Bezier's innovation. During that
time he designed transfer machines for engine block machining. These robot precursors were used by Renault
and sold to competitors around the world.
CADCAM Research and
the Bezier Curve
Bezier began researching CADCAM in 1960 while working on his
UNISURF system. He researched drawing
machines, computer control, interactive free-form curve and surface design, and
3D milling.
Bezier curves are commonly used in vector graphics for
design software. They help model smooth
curves that can be scaled indefinitely.
Applications include computer graphic design, animation, and fonts. Bezier patented and popularized Bezier curves
and Bezier surfaces.
Recognition was
awarded to Bezier for his contributions to computer graphics and interactive
technologies when he received a Steve. A Coons Award in 1985. Bezier died on
November 25, 1999, and The Pierre Bezier Award in his memory recognizes those
with outstanding accomplishments in solid, geometric, and physical modeling and
applications.
