Did anybody try three.js 3d plug in for html5 and Blender 2.5?

The exporter does not show up on my side and I get this error message.
Blender Alpha 2 build 30117 OS X.

I was getting the same error here, on Ubuntu 9.10 with revision 30163.

Fixed it by changing “filename” in line 200 to “filepath”.

However… when I try to export the default cube, I get:

RNA_string_get_alloc: EXPORT_OT_three_js.filepath not found.

Even on my win7 I have the same issue.

This one finally shows up ad exports as well.

there is an rna error about filepath and name being unkown but it writes the file.

I’ve been having a little trouble implementing this.

I created a basic scene with Suzanne, which I unwrapped and baked AO to UV. I exported the model as “monkey.js” (object name: monkey) and the texture as “texture.png”. All that seems to work fine.

In the HTML file for my page, I have:

&lt;div id="canvasContainer""&gt; loading...&lt;/div&gt;
&lt;script type="text/javascript" src="monkey.js"&gt;&lt;/script&gt;
&lt;script type="text/javascript" src="display_monkey.js"&gt; &lt;/script&gt;
&lt;script type="text/javascript"&gt; init("canvasContainer", "texture.png"); &lt;/script&gt;

By placing “document.write()” commands into “display_monkey.js” and observing what shows up on my page, I have learned that the script hangs on a line in the init function:

camera = new THREE.Camera( 75, canvasWidth / canvastHeight, 0.0001, 10000 );

Here’s where I am stuck. I’m not sure why this line isn’t working.

When I start up firefox in a terminal, refreshing my page gives the error:

*** NSPlugin Viewer  *** WARNING: unhandled variable 18 (&lt;unknown variable&gt;) in NPN_GetValue()

It was my understanding that this is a problem with firefox in linux 64 bit environments (which is where I have been working). However, the script stalls in the same place in Windows Vista-32 (using Chrome).

Any ideas?
