How to store the attributes of a geological entity #194

I am a graduate student and my current research direction is the storage of 3D geological models. I was trying to understand whether RINGMesh provides a built-in way to store the description of the geological entities (such as geological time )? The description generally have more than one field. And how to store the color and texture of geological entities? I would be appreciated if you could give me some advices. CC

A GeoModel is a collection of GeoModelMeshEntities (Corner,Line,Surface,Region). For each one you can defines Attributes (properties) on vertices or on elements. These Attributes are managed by an AttributesManager that can be obtained from methods:

vertex_attribute_manager() defined in the GeoModelMeshEntity class
cell/polygone/edge_attribute_manager() defined in the Region/Surface/Line class The AttributesManager is a class from Geogram you can find the documentation here: http://alice.loria.fr/software/geogram/doc/html/classGEO_1_1AttributesManager.html I hope this helps. Francois

Thank you very much @francoisbonneau. Does RINGMesh support the storage of GeoModel colors and textures? Are these attributes managed by an AttributesManager? Thank you again for everything you’ve done.

francoisbonneau commented 5 years ago

You are Welcome. Textures are not supported for now. Attributes stored in the Manager can be seen in RINGMesh-view utility. The code related to ringmeshview is in the "visualize" library.

Thank you very much @francoisbonneau. This is very helpful to me.
