@user21 Hi! yes, please. Could you upload it to Github?

Could someone verify if the PackageData link to Ruebenko's Imtek Mathematica Supplement is functional? I'm not able to download the package

At first I thought that a "pancake pile" of equal 2D configs should work.But I was wrong.
Dr. belisarius
Apr 2, 2016 08:26
I'm still trying to figure out how to use it in 2D
Dr. belisarius
Apr 2, 2016 08:25
I have the 3D software working now but ...

@J.M. I'm using Watershed & Distance transform. That gives me an additive distance. That's why those aren't polygons

@J.M. First power distance Voronoi tessellation, just out of the box:

@J.M. I got it. Not so obvious :(
Dr. belisarius
Apr 1, 2016 03:36
@halirutan Thanks a lot. I also forgot to search by filetype :(
Dr. belisarius
Apr 1, 2016 02:34
see you!
Dr. belisarius
Apr 1, 2016 02:33
@J.M. Well, I go for a cold beer. Too much Voronoi for a day! Thanks again!
Dr. belisarius
Apr 1, 2016 02:31
@J.M. Well,we don't have TB/s here, you know
Dr. belisarius
Apr 1, 2016 02:30
@J.M. Ha! Just arrived. Thanks a lot!

Do you pay by traffic?
Dr. belisarius
Apr 1, 2016 02:28
@J.M. Of course, no problem. But if it is too expensive I can always stress Google harder
Dr. belisarius
Apr 1, 2016 02:21
@J.M. If that doesn't bother you,please
Dr. belisarius
Apr 1, 2016 02:19
@J.M. :D Do you have another link to that article? There is a paywall there ...
Dr. belisarius
Apr 1, 2016 02:17
I haven't touched Fortran since version four :)
Dr. belisarius
Apr 1, 2016 02:15
@J.M. Of course, but I don't like to bother authors with stupid questions. I will go through his code tomorrow
Dr. belisarius
Apr 1, 2016 02:14
@J.M. He just coped the mPower docs. Unhelpful
Dr. belisarius
Apr 1, 2016 02:13
I had to make it work
Dr. belisarius
Apr 1, 2016 02:13
@J.M. Because the Mma interface author didn't understand the output.
Dr. belisarius
Apr 1, 2016 02:12
In some incomprehensible way of course
Dr. belisarius
Apr 1, 2016 02:11
those eigth numbers are the cubes' vertex
Dr. belisarius
Apr 1, 2016 02:10
@J.M. They are "cubes".I found a comment in a 10 KLOC program
Dr. belisarius
Apr 1, 2016 02:09
that's the triangulation
Dr. belisarius
Apr 1, 2016 02:08
What "power diagram"? It spits out this sh*t
Dr. belisarius
Apr 1, 2016 02:08
gosh

@J.M. I was trying to look at that now, but for the delaunay triang that should be clearer
Dr. belisarius
Apr 1, 2016 01:59
but I can't figure out how they are related to the tetrahedron's edges and faces
Dr. belisarius
Apr 1, 2016 01:58
@J.M. those sets of eight integers are the coordinates of the vertex of certain "cubes".
Dr. belisarius
Apr 1, 2016 01:55
@J.M. Import["http://goo.gl/NaH6rM"]["https://i.sstatic.net/UXR2v.png"]

@J.M. Now (after toiling a lot) I have this working
Dr. belisarius
Apr 1, 2016 01:49
No Mma code anywhere.Ha!
Dr. belisarius
Apr 1, 2016 01:48
@J.M. have been peeping code from Voronoi packages and it is frightening hard
Dr. belisarius
Apr 1, 2016 01:47
I'm trying with Watershedcomponents and DistanceTransform. Got a more or less working thing. But agan: too slow
Dr. belisarius
Apr 1, 2016 01:46
@J.M. I think it is too difficult for a good question :(
Dr. belisarius
Apr 1, 2016 01:45
@J.M. yes, I already have a working program, using nearest. But it is way too slow
Dr. belisarius
Apr 1, 2016 01:44
@J.M. additively weighted power Voronoi tessellations, to be precise
Dr. belisarius
Apr 1, 2016 01:41
@J.M. Yup
Dr. belisarius
Apr 1, 2016 00:56
@halirutan BTW, got it working. The problem now is that I can't understand the results! ha!
Dr. belisarius
Apr 1, 2016 00:54
@halirutan Don't forget that the laziness factor is also in the equation, and squared
Dr. belisarius
Mar 31, 2016 20:45
@halirutan Yeah,well. I don't want to implement my own power distance algo!
