Asus EEEPC shows only the empty canvas

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Loading http://dhtx.de/it/ek/Projekt%203D-Drucker.html on a smaller device 
like Netbooks.
2.
3.

What is the expected output? What do you see instead?
On my Desktop PC i see my "3D Printer under Dev." very nicely rendered.
On my Netbook (Asus EEEPC) i see only the empty canvas.

Please provide any additional information below.
I've investigated with Firebug (see on bottom)but i can't find the exact 
reason. I think too much Data perhaps!?
Is it planned to work with zipped Data?
Please answer, i'm an enthusiastic user of your Script!

It seems to be a cross-domain issue. In 
http://www.dhtx.de/it/ek/Projekt%203D-Drucker.html I found this:

  viewer.setParameter('SceneUrl', 'http://dhtx.de/it/ek/Dieterbot.obj');

As you can see in the implementation, jsc3d uses XmlHttpRequest to load object 
models. An absolute path description such as 
'http://dhtx.de/it/ek/Dieterbot.obj' will cause a cross-domain resource 
request. This will success only when 1) The server side must be configured 
properly to response to this kind of requests; 2) The browser has to support 
CORS feature.

The soluiton is quite straightforward. Just put the obj/mtl files (also image 
files if any) into the same domain with your page and change the model path 
which will be send to jsc3d to a relative form:

  viewer.setParameter('SceneUrl', '...(your-model-path)/Dieterbot.obj');

This makes it work correctly since the cross-domian request is removed.

If your application has to employ cross-domian requests anyway, you may find 
this link http://enable-cors.org/ very helpful on how to make it work.
