We aim at studying various structures and algorithms in other spaces than Rd, from a computational geometry viewpoint. Proposing algorithms operating in such spaces requires a prior deep study of the mathematical properties of the objects considered, which raises new fundamental and difficult questions that we want to tackle.
A key characteristic of the project is its
interdisciplinarity: it gathers approaches, knowledge, and tools in
mathematics and computer science.
A mathematical study of the considered objects will be performed, together with the design of algorithms when applicable. Algorithms will be analyzed both in theory and in practice after prototype implementations. In the long term, implementations should be improved whenever it makes sense to target longer-term integrations into CGAL, in order to disseminate our results to end-users.
Challenges. The global difficulty of this project is intrinsic to the differences between the classical Euclidean spaces and the spaces that we consider (to spot only one concrete example: translations in the hyperbolic plane do not commute). This prevents known algorithms of computational geometry from naturally extending to other spaces. The mathematical difficulties are real and new ideas will be necessary. The challenge is to provide new mathematical foundations for computational geometry, in order to allow the emergence of algorithms that will be both efficient in theory and effective in practice.
