The Discrete and Computational Geometry Laboratory is formed
by Otfried Cheong
and his graduate students and postdocs.
The lab is currently empty, as Otfried Cheong is on leave from
We do research in two related areas:
- Computational Geometry
Computational Geometry is the area of computer science
that studies efficient algorithms for geometric problems. The
problems studied come from applications in graphics, CAD,
robotics, GIS, and other areas of geometric computation, but
are studied from a theoretical point of view. Algorithms are
formally analyzed and proven correct.
Otfried Cheong is one of the authors of
the standard textbook on
- Discrete Geometry
geometry is an area of mathematics that studies
combinatorial properties of geometric objects. Going back to
Kepler and Gauss, the field owes much to the work of Paul
We have quite a few visitors from all over the world. See
the visitor log for details.
