Research activities

Keyword(s)

Geometric Algebras, Clifford algebras, Grassmann exterior algebras, continuous and discrete geometry, global visibility.

Current work

Global visibility computation (visibility between two surface elements) in a space of lines.

Algebraic formulation of the problem, then validation of the formulation in any dimension.
Solution to the problem of the minimal polytope (smallest (in term of inclusion) convex set representing the lines stabbing two convex faces).
Exact handling of degeneracies
Implementation in the 3D case:

Improvement of previous algorithmic solutions
Handling of silhouettes (exposition of singularities and development of solutions to handle these singularities)

Projects

Ph. D. project (done): global visibility computation: from theory to practice.
Current projects: application of geometric algebras to discret geometry

Modeling of general discrete linear manifolds (generalization of the Reveilles line to any linear manifold in any dimension).
Discrete rotations in Clifford algebras.
Line reconstruction/recognition problem in a discrete image: generalization to any discrete linear manifold recognition.
