Vegas is an INRIA research group dedicated to computational geometry.
It is part of the INRIA Nancy - Grand Est
research center and LORIA laboratory.
Our research is focused on the two followings themes.
Curved geometric objects, such as real algebraic curves and surfaces, are important in geometric computing as they arise naturally in many problems in computer sciences, mathematics, physics and chemistry. We work on the design and implementation of exact and efficient algorithms for manipulating such primitives.
Understanding and computing visibility relations between three-dimensional objects are central questions in many geometric problems and in areas such as computer graphics or computer vision. We work on exact visibility computations, such as surface-to-surface visibility queries, with a focus on the theory of sets of lines and line segments encoding these relations.
