QUESTION
I just started to work with 3D meshes, oriented to be used for finite element analysis. I would like to model inclusions for materials (any shape, but mainly interested in spheres and ellipsoids) in a cube-like matrix. These inclusions shouldn't be coincident with each other.
So I was thinking to use some sort of package for python which can plot primitive objects, look for their intersection (if it exists) and export the geometry (or mesh it and export it). In case of spheres, I was coding my own solution, but I think it will be very difficult to expand it for any other shape than spheres.
After a couple of days looking for an appropriate library/module, I can't decide which one I should use.
I would like to use python as the main language since it is easy, open source and I already know a bit. Hence checked this link: Good geometry library in python?
But:
- SymPy. It seems it is only for 2D objects.
- pyeuclid. Looks discontinued in its google code page.
- CGAL. It seems the most advanced, but I can't find if it does intersections.
- geometry-simple. Also discontinued, and I believe it does not handle 3D objects.
- pythonocc. The lack of documentation is an important issue here.
- Open mesh. It seems a good alternative but I can't see if it does intersections.
I might be missing some features or libraries. Sorry about it.
If it is really necessary and useful, I could try to use C++ which it seems has more libraries for geometry as stated in here, here and here. Also, I think I should mention I work mainly on Windows 10, and my experience with Linux is little but I could challenge myself.
To summarize my question: Is there any good library in python (if possible) which can find intersections between 3D objects? Am I missing any feature or library I should know? I would appreciate a lot any suggestion in the right direction.
Thank very much in advance!

QUESTION
Im trying to write an osgi-application that should make use of the org.elasticsearch.client.RestHighLevelClient. For this I have added the bundle servicemix.bundles.elasticsearch-client since it exports org.elasticsearch.client with the needed RestHighLevelClient. Apparently though, it seems that the RestHighLevelClient needs servicemix.bundles.elasticsearch (amongst others) to work so I add that aswell - both of the same version. Both of the bundles export org.elasticsearch.client but with different content. Everything loads as expected and I can verify the exported packages.
EDIT: The problem that im getting reviels it self as a ClassNotFound-exception for org.elasticsearch.client.RestHighLevelClient. Which is odd since I can view that the elasticsearch-client is available and exporting the requred package.
My interpretation is that Karaf doesent seem to be able to handle shared packages. It seem to load one of the bundles that have the required package to suffice the requirement from my application-feature, and after that decides that it is enough even though the needed class actually exist in the the other bundle.
After comments from @ChristianSchneider and gaining some more understanding I have updated my configuration. However, the issue still remains.
I now have a elastisearch-client6-feature and an elasticsearch6-feature
...ANSWER
Answered 2018-Aug-15 at 21:01I had the same problem and this is what I did...
- Go to https://jar-download.com/artifacts/org.elasticsearch.client/elasticsearch-rest-high-level-client/all-versions which is a site that lets you download maven artifacts as well as all their dependencies, select the version you want.
- After selecting the version click the red download button and it will download a zip file with all the elastic search jars and required dependencies.After downloading unzip the jar on your local file system.
- Create a bundle like com.mycompany.thirdparty.elasticsearch
- Create a lib folder in the root of the bundle and copy/paste all those jars you unzipped from the download into that folder.
- Using eclipse MANIFEST editor go to Runtime Tab, in the class path section add all the jars in the lib folder. Then for exported packages click add and add all the packages available.
This creates a bundle that has elastic search and all its dependencies which are exported to other bundles that import elastic search packages or add the bundle as a dependency.
Hope that gets you in the right direction, its easiest to do this in eclipse with the MANIFEST editor because it automatically updates build.properties files.
