Programming Topological Operations for Visual Illustrations in an Introductory Geomorphology Course

Abstract : In the context of teaching geomorphology phenomena, producing illustrations and animations can be a tedious process. We propose an experimental framework, dedicated to 3D erosion and sedimentation modeling written in C++, combined with an existing topological modeler. Using the ''generalized maps'' as the underlying 3D model, we process each case of collision between elements in the scene in order to guarantee both topological and geometrical coherence during user-defined animations. Erosion and sedimentation operations can be combined to manipulate evolution scenarios leading for example to the creation of arches, bridges, tunnels or caves. Some of these scenarios, implemented in our framework with the help of a geology teacher, are presented in this paper in order to show the technical feasibility of our project before developing new ones.
