I got "yet another" Meshtastic device, lol

this time, I got the "RAKwireless WisMesh Pocket v2"

it arrived today, and so far, it is doing amazing, even for the stock antenna it comes with, lol

and, it's so tiny! 😂

@h4ckernews this is about #mesh in software applications but not related to #mesh in the sense of #meshing #meshtastic devices.

I finally have a site for my mesh booleans! It's been almost 3 years since my EMBER paper. We basically took the "imul" i64 x i64 -> i128 instruction and built a geometry kernel out of that.

So, if you like robust, exact, high-performance mesh booleans (for graphics, VFX, 3D printing, CAE, ...), you might find this interesting: https://solidean.com/

(This is my commercial project, though we want to open-source the exact predicates & constructions in the future)

Langsam aber sicher trudelt meine MeshCore-Hardware ein. Drei WisBlocks sind schon als Repeater programmiert. Jetzt warte ich noch auf Solarpanel und Antennen, dann werde ich die Teile mal provisorisch an ihre zukünftigen Orte hängen und den Empfang testen.

Nachdem ich diesen Thread gelesen habe, bin ich froh, mich nicht für Meshtastic entschieden zu haben:

Went with another classic, the dragon statue.

This shows triangulated surface remeshing using a (very basic) #JuliaLang wrapper for @BrunoLevy01 et al.'s fantastic Geogram library (https://github.com/BrunoLevy/geogram).

Coming soon to #comodo: constrained #Delaunay triangulations. Which I decided needs parameterized #Batman curves too for testing purposes 🦇

Recently, I've put a lot of effort in completing the documentation of 🔍 FElupe, especially its API reference. There is still room for improvement, but I consider it to be in a fairly good shape now 📝. There are also new tutorials 🎓 and examples 🧮 - have a look if you haven't already! If you have ideas 💡 on how to improve it, please let me know!

I consider 🕸️ meshio to be probably THE BEST open-source library related to #scientificcomputing and #meshing. 🎉 Kudos to the authors and contributors! 🎉

Have you ever used meshio?

#Meshing tauchte zum ersten Mal im Protokoll der 137. Sitzung des 20. Deutschen Bundestages am 16.11.2023 auf. Es wurde im Rahmen der Rede von Helge Limburg (GRÜNE) gesagt.

@villares Great! In FElupe, I eliminated one loop for performance reasons: First, I create a line-mesh and then expand it to a rectangle.

import felupe as fem

mesh = fem.Rectangle(a=(0, 0), b=(100, 100), n=(6, 6))

Here you'll find the rectangle-function

and here the expand-tool:

Hey, exciting news about quad/hex-meshing: Easily create planar quad meshes between two line meshes by interpolation. Same applies for hex meshes between two quad meshes. Will be included in the upcoming release 7.7.0 of FElupe on PyPI!

On to a bit of #EngineeringGeology and #GeotechnicalEngineering, the erosion is a serious problem for any structures built on or near the coast and there is a mainline railway track on the route to London which runs along it on this stretch. #NetworkRail is busy trying to stabilize and strengthen the cliffs using #RockAnchor, #RockBolts and #meshing to retard the process. Here you can see workers #abseiling as part of their work.

Added textured OBJ model import to GIBBON. The OBJ import supports mixed faces (e.g. tri+quads).
The demo video shows coupled refinement of both the geometry and texture data for an imported model.

Also useful for resampling digital image correlation data on 3D surfaces.

Checking out "Taubin" smoothing. Looks great for smoothing voxel derived meshes. Video shows voxel mesh (red) of a femur and the Taubin smoothed surface retrieved (white).

One of Taubin's papers: https://doi.org/10.1109/ICCV.1995.466848

@ahafeezs @FreeCAD Still learning a lot, actually I have no clue what most of the icons do 😅, but I can find my way around with the sketcher and part design.
Can you link a good tutorial to get into #meshing with @FreeCAD for fluid mechanics (volume of fluid, hexahedral like). #CFD, #CAD

#Upcycling-Tipp des Tages: Altes TV/SAT-Kabel für Gigabit-#LAN weiterverwenden

Wenn das #WLAN nicht die gewünschte Reichweite hat, werden oft #Repeater / #Meshing oder #PLC genutzt. Aber oft genug ist das leider keine ausreichende Lösung.

Falls ihr ein vorhandenes #Koax-Kabel habt: Das lässt sich mittels #MoCA-Adaptern für Gigabit-LAN verwenden.

Hat sich bei mir bewährt. Ich hab die kostengünstigen Adapter "Hirschmann INCA 1G" im Einsatz:
