I also have nashorn examples here: <a href="https://github.com/coderextreme/X3DJSONLD/tree/master/src/main/nashorn/net/coderextreme/data">https://github.com/coderextreme/X3DJSONLD/tree/master/src/main/nashorn/net/coderextreme/data</a> and node.js examples here: <a href="https://github.com/coderextreme/X3DJSONLD/tree/master/src/main/node/net/coderextreme/data">https://github.com/coderextreme/X3DJSONLD/tree/master/src/main/node/net/coderextreme/data</a> (requires java-npm library). The JS APIs are written on top of X3DJSAIL (direct API map of functions to constructors): <a href="http://www.web3d.org/specifications/java/X3DJSAIL.html">http://www.web3d.org/specifications/java/X3DJSAIL.html</a> and thus, are server-side. I currently have no plans to write a pure JS API, but you might try using JSweet to convert Java to JS or TS (problems with converting jars to to JS). Maybe start with this: https://github.com/coderextreme/JavaSceneAuthoringInterfaceLibrary</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I have found it easier to convert JSON to DOM, because all the infrastructure in X3DOM is set up to use DOM and the infrastructure in X_ITE is to use DOM and VRML. While it might be preferable to write native JSON events (and I have done things like this, you are welcome to help), the work is unfinished. Real PROTOs are present in X_ITE, but not X3DOM (there is a “proto expander” for JSON documents). I don’t know the proper status of Scripts in X3DOM. What’s important there is routing to and from the Script.</p><p class=MsoNormal><br>If you were to take on a pure JS API, I would recommend using modules in JavaScript, if they are still in the standard. That way you can limit the amount of code you load.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><br>There is very little reason to use a JS library unless you are writing Scripts in my examples. I recommend getting help here and other places in order to get the minimum of scripting required (for example, Emitters encapsulate random numbers).</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If you share your use cases, you may be able to get a better leg up. It sure helped me.</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Good luck,</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>John</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>>> I also had some curiosity about what it takes to WRITE a JS library like the X3D "parser", I guess you could call it....?</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>>John Carlson has created X3DJSONLD open-source library:</p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>> https://github.com/coderextreme/X3DJSONLD</p></div></body></html>
