I would like to import JSON(made by three.js) data into Maya.
I found exporter of Maya, but couldn't find importer of Maya.
Is there good way to do it?
There are currently no Three.js JSON importer.
The Three.js JSON is meant to be a runtime format, used by Three.js for rendering in WebGL. Usually, you would export to the JSON format when you want to use it for the web. It is not meant to be a storage format.
There are other more common "interchange" formats like FBX, Collada, or OBJ, that are meant to be for storage and for passing around between different people and software packages.

I would like to build a CNC manufacturability analysis app using Autodesk Forge.
Setting the computational geometry algorithms aside, what kind of geometrical data can I extract from CAD files using this platform? also, is there an existing app I am unaware of?
Thanks
Depending on the input file format you can convert to different other formats:
Supported Translations
Though it's not obvious from the above list, all input formats support conversion to OBJ format, which can also be done at subcomponent level - so you don't have to export the whole model to OBJ.
Here is a sample that lets you access your files from A360 and convert them into whatever format is currently supported for them:

I guess not much people need to import three.js json file to Blender, but I lost my original Blender file and want to recreate it from json that I exported earlier.
Latest three.js git only has exporter and no importer.
I tried using old json importer (from this link https://github.com/Bangybug/three.js/tree/master/utils/exporters/blender/2.71/scripts/addons/io_mesh_threejs) but it does not load back UV maps, only model and textures, so I wonder if there is some importer that could do this?
Unfortunately, there currently is no working importer to get three.js models into blender. You could try to load the object in three.js and then export it using the THREE.OBJExporter(). You might have a good chance to import that resulting obj-file into blender.
I have been looking at ways to convert a JSON file into a GraphJSON graph and I have come across the GraphJSON Reader and Writer Library.
However, what I do not really understand is whether I can read out directly from a path where a JSON file resides and parse it into a graph/GraphJSON.
Can you help?
This is how I would solve this issue:
Read your JSON files using GSON or Jackson, then
Feed this data into a subclass of Vertex/Edge of your implementation of these Tinkerpop 3 interfaces.
Use the GraphSON writer methods to "graphitise" your data, save your data into an OutputStream.
I'm assuming you're using Tinkerpop3 and Titan 1.0.0, this is the right documentation.
Good luck!
P.S: If you're doing this for the sack of importing data into Titan, you might be overcomplicating the issue of data import. Just import it straight away.
I have a json file containing network data that I'd like to visualize using a network visualization software like Gephi. But Gephi does not accept this type of files. Is there a way to convert the json file or are there any other network visualization softwares out there that can? I am a Mac user.
You need to use networkx in Python, construct your graph and Export your graph in a format that Gephi can load such as gexfor graphml. See the link for examples of the supported formats. Apparently R is an option, too, provided that igraph has a json reader
Visjs can import Gephi JSON and display it as a graph/network:
http://visjs.org/examples/network/data/importingFromGephi.html
You probably could adapt your JSON to fit this format.
I want to render 3D graphics files of autodesk (.dwg and .dwf) using three.js but three.js requires 3D data to be in json format. So, I need to convert these files to three.js readable json format. I tried searching on the internet but couldn't find any solution. Can anyone tell me a good converter for these files?
Thanks in advance.
In fact Autodesk already have a converter & wegbl viewer. Go to http://developer.autodesk.com and get a key for View & Data API. There is a server side REST API that allow you to upload a CAD file and convert to a JSON stream. You can hook to it and get the output. Or, even easier, just use the JavaScript client side API to embed the viewer on your website/app
Update
The API was renamed to Model Derivative + Viewer, the first translates the source file (e.g. DWG, RVT and many others) to a web-friendly format that can be viewed on the second, which is based on Three.js (and can be customized).
