Description
I am analyzing an error related to AR and XML3D enablers. Due to rendering problems I finally tried the Teapot tutorial example. https://github.com/xml3d/xml3d.js/wiki/The-Basics-of-XML3D . Nothing showed up. The browser is Firefox 38.0.5
Console log:

The "renderer is undefined" message count increases, when I move cursor above the possible rendering area.
The browser is Firefox 38.0.5
It seems I cannot inspect further without help from XML3D people.
This is related to https://jira.fiware.org/browse/HELP-3152 .
Activity
I tried Chrome. I got better error messages. E.g.: "XMLHttpRequest cannot load file:///C:/Users/ariok_000/Documents/Projects/AR/Finalizing/xml3d_examples/teapot/resource/teapot.json. Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https, chrome-extension-resource.loadDocument @ xml3d.js:7661". It seems that XML3D does not work on local files. Perhaps it should be documented in BIG RED BLINKING characters in the first page of everything related to XML3D.
Seems my last comment I have sent by email got lost ...
Indeed, an XML3D scene needs to be deployed on a web server and can not be run from the local filesystem, as soon as it uses external references to resource files. This fact is included in the FIWARE User & Programmer's Guide, but, as you pointed out, missing in the Quickstart-Guide Wiki.
I am going to report this issue to the XML3D guys. Please let me know if the example now runs correctly.
Putting the teapot.html and resource/teapot.json under Wamp local server helped. Works now. Only thing remaining is highlighting the fact that it does not run from local file without server.
I have copy and pasted the code from the example wiki and it worked without problems.
Can you provide me with the code of your test scene please?
