FreeCAD Trails Workbench (Transportation and Geomatics)

[vocx]

Are both Add-Ons Geodata and Geomatic compatible? can they both exist at the same time in FreeCAD (both installed at the same time)?

Thanks

The GeoData workbench was started by microelly2 but he never completed it. It was more or less prototype code.

Then, Hakan started Geomatics Workbench using code from microelly's GeoData. So, GeoData is more or less obsolete, as more functionality was developed in Geomatics Workbench.

However, some time later Hakan said he didn't want to continue development of the Geomatics workbench (post). Nevertheless, shortly afterwards bidandou decided he could continue the project and became the second main developer and maintainer (post).

So, you shouldn't use GeoData; you should use Geomatics, and preferably direct your questions to bidandou in the GitHub repository.

OK Thanks a lot.

I don't think bidandou works on wb anymore.

I added new triangulation algorithm based on Delaunator. Its very fast. I ported it from js to python.

Github link of Delaunator: https://github.com/HakanSeven12/Delaunator-Python

That's pretty dang cool

Fantastic!

it's intersting, but I made a test with scipy (qhull in the backround)

Code: Select all

from scipy.spatial import Voronoi, voronoi_plot_2d

print ("scipy")
start_time = time.clock()
vor = Voronoi(points)

#
# delaunay
#
edges=[]
col=[]
for r in  vor.ridge_points:
	pts=[points[v] for v in r if v  !=  -1]
	if len(pts)>1:
		for i in range(len(pts)-1):
			pa=pts[i]
			pb=pts[i+1]
			xa,ya=pa[0],pa[1]
			xb,yb=pb[0],pb[1]
			edges += [(xa,ya,xb,yb)]

triangulation_time = time.clock() - start_time
print(triangulation_time)
    

with the same test dataset these are the test time on my computer:

pure python: 250 s
scipy time: 4.9 s

Yes. Scipy more faster than delaunator but it's not included in FreeCAD. So I want to use minimal python code for triangulation and I'm happy with result. Here is the comparison: https://forum.freecadweb.org/viewtopic. ... 94#p373471

Hello,
I don't know if it's the right place.
But I am using Geomatics WB, which will be the best upgrade for my scope of work.
I have uploaded a .xyz file, but I don't understand how to set the units. It always imports as "mm", though i have set Freecad to m units.
What am I missing? I followed installation steps and set the decimals to 10 because I sometimes have longer decimals.

340393.42433041 5073227.2524919 1759.39
340395.42354515 5073227.2524919 1759.22
340397.42275989 5073227.2524919 1759.0601

This is a part of my xyz file

Help please.
