Status:
base class, extends NXcg_primitive_set
Description:
Computational geometry description of a geodesic mesh. ...
Computational geometry description of a geodesic mesh.
A geodesic surface mesh is a triangulated surface mesh with metadata which can be used as an approximation to describe the surface of a sphere. Triangulation of spheres are commonly used in Materials Science for quantifying texture of materials, i.e. the relative rotation of crystals to sample directions.
For additional details or an introduction into the topic of geodesic meshes see (from which specifically the section on subdivision schemes is relevant).
Earth scientists have specific demands and different views about what should be included in such a base class, given that nested geodesic meshes are a key component of climate modelling software. For now we propose to use this base class as a container for organizing data related to geodesic meshes.
Specifically an instance of this base class should detail the rule set how e.g. a geodesic (surface) mesh was instantiated as there are many possibilities to do so.
