[Fiware-miwi] txml to xml3d converter test

[toni at playsign.net]

Hi again, a note about a little beginning of a software tool for change:


I started an experimental txml (<)-> xml3d converter:

https://github.com/playsign/txml-xml3d


An example conversion is shown on the webpage (readme) there.


This was inspired by the earlier discussion about how the mapping could look like, and by the repeated attempts to illustrate how the reX custom components we are used to can be preserved in a html & xml3d style human friendly xml.


NOTE: this does not have anything to do with renderer selection or anything like that but is an exploration of formalizing the data model mapping. To make talks about it more concrete. Inspired by the POI & real-world mapping & custom components discussion and obviously the door example which is used as the minimal test data here now.


Is very much work-in-progress, only little partial functionality and some of the code is crappy etc. I just wrote it in the evening for fun now. Did help a lot in understanding better what it would take to actually complete it if we end up finding this useful (we’dneed a mapping of attribute names, ‘Mesh ref’ <-> ‘src’ etc).


Might be fun to run some reX scenes like the bundled Tundra examples through this to see what they look like.. Those live in https://github.com/realXtend/naali/tree/tundra2/bin/scenes


It might be interesting vice versa too, from xml3d to txml .. am not sure if that’d really teach anything though. Is ofc a possible way to add xml3d support to Tundra (if we need it on the server). For real usage might be better to write a xml3d loader there (either in js or c++). This Python converter is mainly just exploration to understand the mapping better and hopefully make it more concrete for others as well - I already had code and experience from converting TXML with Py’s ElementTree so this was easy to do. Can be completed to production quality if needed (for example to use as a conversion web service .. http post txml/xml3d to it and get the other back).


Cheers,

~Toni


P.S. had a brief look of the arch desc, seems interesting but didn’t get much yet, too tired now -- will read properly tomorrow.
