For anyone with this same issue:
* We made it work by using iframe on iframe.
Read carefully:
In the applications folder we have now 2 .HTML files.
index.html
furniture.html
The scenery is in furniture_configurator.html
All scripts and DIVs, are written in index.html,
Right after body we introduce the iframe:
<body>
<iframe style=”position:absolute;top:0;left:0; width:100%; height:100%;” allowfullscreen frameborder=”0″ src=”./furniture.html”></iframe>
…
…
</body>
So we have this:
<parent_page_wordpress.html>
iframe=index.html
<index.html>
iframe src=furniture.html
