Der einzige, aber entscheidende Unterschied zwischen beiden Devices ist der externe Antennenanschluss. Ich bin auf die Reichweite gespannt. πŸ˜€

Computing 500 Laplacian eigenfunctions on a violin with #geogram, displayed in #graphite.

@enron And now there is something even new coming, #Geogram, https://geogram.radio/.

From first reading, it reads from the network user side more close to #reticulum. But why building something new here, too?

(I have not dug into #geogram more than cross-reading the landing page https://geogram.radio/, though.)

When the internet goes down, Geogram keeps going. Direct device-to-device communication without servers, accounts, or infrastructure you don't control.

A good crash-test for #geogram: one of the standard OpenSCAD test file, but with a level-5 Menger sponge (instead of level-3 in the original), intersected with a diagonal plane.

There are 100K facets with intersections, and some of them have several thousand intersections in the same facet.

Final mesh has 1.4M vertices and 3.8M faces,

The CSG engine and the geogram+ arithmetic kernel marketed by Tessael go brrr !!!

#geogram 1.9.7 is out !

Geogram is a software library of geometric algorithms, it has mesh intersection, remeshing, CSG, Delaunay and Voronoi in 2D and 3D, constrained Delaunay triangulation in 2D ... and much more !

New in this version: improved compatibility with OpenSCAD.

Is #geogram's Constrained Delaunay Triangulation robust ?
... on the testbench !

Minkowski sum starts to fly in #geogram (WIP...)
#geogram + #graphite + #blender Python scripting = robust CSG directly available in Blender !
Everything is a numpy array.
Seems that some folks are taking a look at the open-source implementation in #geogram !
