Développement d'un langage de programmation dédié à la modélisation géométrique à base topologique, application à la reconstruction de modèles géologiques 3D

Abstract : Geometric modeling is used in various scopes for 3D object construction, animation or simulations. Each domain must cope with its constraints and should have its dedicated tool. In fact, several common characteristics of different domains are factored in a single tool. These modelers contain sets of basic operations that the user composes to build his objects. For more specific operations, current common tools offer API.Jerboa’s platform allows to generate personalized geometrical operations. These are defined by graph transformation rules. During their design, many automated verifications are done for the preserving of object consistency. They also be enriched with additional properties. Our contribution consists in extending the Jerboa language with scripts to compose rules and define complex operations. We also extended automated verifications, in particular to ensure geometric consistaency. Finally, we modified operations application process, in order to increase user control possibilities.To validate this approach, we have implemented a geological dedicated modeler for subsoil modeling, in collaboration with Geosiris Company. We defined a workflow with Geosiris that follows specific geological reconstruction constraints. Thanks to the Jerboa rapid prototyping mecanism, we developped and quickly tested several subsoil reconstruction algorithms, and apply them to real data provided by the company.
