I need to convert stl file json using python, is there any way to do this using python programming
Here's a project that will help you to convert .stl files to JSON.
Project GitHub
Also, here's a python module called numpy-stl. It offers a wide range of functionalities for directly working on .stl files.

is there a way to convert json files into jsonnet files?
I am working on grafana dashboards as code and need to convert a json file into jsonnet. Or is there a good guide on how to create panels in Grfana except the official Jsonnet website? I would be glad if I recieved any help from you!
JSON files are "technically" jsonnet files already, you can prettify them to look like jsonnet with:
jsonnetfmt file.json > file.jsonnet
Of course, the above is just syntax-sugar'izing the original JSON file.
If you want to build Grafana dashboards in a programmatic way, grafonnet-lib would be the way to go
In my project I have proto file, the respective class files also. I have probuf binary data as blob file format. How can I convert this file to json file? I am very new to Scala.
I came across https://scalapb.github.io/docs/ site. It is not very clear to me. I do not want to install this whole but rather just make use of Json4s to convert protobuf data to json data.
Any pointers? Which library can I use and how can I use it?
The .proto files are your source of truth. There should be no "respective class files"
ScalaPB should be used as an SBT plugin. It will generate "managed" code when you compile your project. That managed code will consist of case classes that mirror the definitions in the proto files and companion objects that can serialize the protobufs.
Managed code is code you do not edit as a user. You won't even see it unless you look for it in the target directory. If your proto files change, the compiler will re-create the proper code to reflect those changes. That is why you should not hand-create these case class files.
Then apply their Json4s helper-lib which cuts down on a few steps
I am looking for how can we use opennurbs c++ sdk to convert 3dm file format to stl or obj file format. I have already tried looking its documentation but got nothing much helpful.
documentation link [http://developer.rhino3d.com/guides/#opennurbs][1]
another link: [http://wiki.mcneel.com/developer/opennurbs/home][1]
Is it possible to convert 3dm file format to stl or obj file format using some API of opennurbs sdk or any other sdk. If yes then which API or sdk can be used ?
openNURBS by itself only supports Rhino's 3DM file format. The 3DM file format can support both mesh and NURBS geometry, but STL only supports meshes. OBJ can support both.
You can use Rhino to open the 3DM file and save as OBJ or STL. Rhino also includes a robust mesher that can convert the NURBS geometry into a mesh for STL output.
You might also consider Okino's PolyTrans software for doing file conversions automatically.
Im trying out the MarkLogic Java API and would want to bulk upload some files with the extension .csv
I'm not sure what to use, since the Java API only supports JSON, XML, and TXT files.
How do I batch upload files using the MarkLogic Java api? Do i convert everything to JSON?
Do i convert everything to JSON?
Yes, that is a common way to do it.
If you would like additional examples of how you can wrangle CSV with the Java Client API, check out OpenCSVBatcherExample and JacksonDatabindTest.testDatabindingThirdPartyPojoWithMixinAnnotations. The first demonstrates converting the csv to XML and using a custom REST extension. The second example (well, unit test...) demonstrates converting the csv to JSON and using the batch upload (Bulk Writes) capabilities Justin linked to.
If you have CSV files on your filesystem, I’d start with mlcp, as suggested above. It will handle all of the parsing and splitting into multiple transactions/batches for you. Take a look at the mlcp documentation for more details and some example configurations.
If you’d like more control over the parsing and splitting logic than mlcp gives you out-of-the-box or you’re getting CSV from some other source (i.e. not files on the filesystem), you can use the Java Client API. The Java Client API allows you to efficiently write batches using a WriteSet. Take a look at the “Bulk Writes” example.
According to your reply to Justin, you cannot use MLCP because it is command line and you need to integrate it into a web portal.
Well, MLCP is released as open cource software under the Apache2 licence. So if you are happy with this licence, then you have the source to integrate.
But what I see as your main problem statement is more specific:
How can I create miltiple XML OR JSON documents from a CSV file [allowing the use of the java API to then upload them as documents in MarkLogic]
With that specific problem statement:
1) have a look at SplitDelimitedTextReader.java from the mlcp source
2) try some java libraries for this purpose such as http://jsefa.sourceforge.net/quick-tutorial.html
I'd really like to use STL models with XML3d. Is there a way to convert back and forth between these formats?
You can convert STL files to XML3D using the Blender exporter for instance:
https://github.com/ksons/xml3d-blender-exporter
Another option is to write a plug-in for STL files that allow to reference STL files from <mesh> and <data> elements:
<mesh src="foo/bar.stl"/>
This would be very similar to the existing plug-ins for MeshLab/JSON and OpenCTM files:
http://xml3d.github.io/xml3d-examples/examples/meshlab/meshlab.html
http://xml3d.github.io/xml3d-examples/examples/openctm/openctm.html
We've just released a new converter that uses the Open Asset Import Library to convert many 3D formats (including STL) to XML3D's asset format:
https://github.com/csvurt/assimp2xml3d
It can't convert from XML3D back to other formats, but this might be something we add in the future.
There is a plug-in for STL file now:
https://github.com/xml3d/xml3d-stl-plugin
It allows using STL files as simple as:
<mesh src="../path/to/model.stl"></mesh>
