[image] Meshes.jl provides efficient implementations of concepts from computational geometry and finite element analysis. It promotes rigorous mathematical definitions of spatial discretizations (a.k.a. meshes) that are adequate for describing general manifolds embedded in Rⁿ, including surfaces d…

Hey, I’ve seen above that Meshes was a fork from GeometryBasics. However it seems the metadata part of GeometryBasics was not kept. What is the correct practice to add metadata to Meshes meshes ?

Check the Geospatial Data Science with Julia book: https://juliaearth.github.io/geospatial-data-science-with-julia Use a GeoTable.

Thanks for the tip ! I just went through the book, and I feel like I’m missing some things. It feels like everything is based on the data values at geometry points, but no data can be linked directly with the elements, is that so ? How do you dispatch plotting recipes based on a given georef. In m…

The geometry column can contain any geometry, not just points. The recipes are dispatched on Domain types which are collections of geometries. Please let us know if something is not clear. Better ask on Zulip to avoid spamming everyone in this thread.

Meshes.jl v0.43 @eliascarv and I are super excited to share a new release of the project, after months of hard work to formalize coordinate reference systems (CRS) with Julia types. This release comes with many breaking changes, which are needed for real-world usage of meshes in industrial applicati…

This is great to see! What was the motivation for the naming of to function? It seems a bit strange to me. I would have never guessed it returns the vector (Vec) from the origin. Why not just allow people to use Vec?

This function takes any point and returns the geometric vector point - origin, i.e. our Vec. The motivation in the name comes from origin to point. This is a very specific operation that is not very useful in curved manifolds for example, where the vector connecting the origin of the CRS to the poi…

Awesome news! Even though I’m not the target audience for this feature, I’m happy to see the active development of the package. I’m wondering if there are any plans for Makie.jl to use Meshes.jl under the hood? Or Meshes.jl doesn’t want to be the new GeometryBasics.jl package.

I can answer from the Meshes.jl side that we don’t see any issue with this idea of providing the geometric processing infrastructure for Makie.jl. Both projects would certainly benefit from tons of features, and human resources would be used more wisely.

v0.43 automatically adds units to all the points, which are by default [m] . Is it possible to use a customized unit system, or simply turn off the units?
