3.3.3.44. NXcg_geodesic_mesh¶
Status:
base class (contribution), extends NXobject
Description:
Computational geometry description of a geodesic mesh. ...
Computational geometry description of a geodesic mesh.
People from geodesic/surveyors will likely 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 tools. For now we propose to use this base class as a container to organize metadata and data related to geodesic meshes.
Specifically an instance of this base class should detail the rule set how how the geodesic (surface) mesh was instantiated as there are many possibilities. A geodesic surface mesh is in this sense a triangulated surface mesh with metadata. For additional details as an introduction into the topic see e.g.:
Here, especially the section on subdivision schemes is relevant.
Symbols:
