Hi,

I want to develop an OBJ to COLLADA converter in order to show 3d contents in Google Earth.
By using the Xith library, I have built the OBJ to COLLADA converter but Google Earth doesn't show the converted file because it doesn't support the <polygon> and <polylist> tags.
So how can I convert the <polygon> and <polylist> tags to the <triangles> tag?

Hi, Villox. Welcome to Xith3D .

Unfortunately I have no idea of the COLLADA format. I just wanted to tell you, that Amos Wenger is currently investigating the COLLADA format. Sou you should wait a few hours until he comes back. Then he can probably tell you something about it.

btw. Did you consider using blender to convert from OBJ to COLLADA?

Hi Villox : as Marvin, said you'd probably better use Blender3D for conversion anyway.

That said, I cannot help you with the COLLADA lib which is currently in xith-tk because I haven't made it and I don't want to investigate it.

I'm currently making a COLLADA loader myself (primarily for Xith3D, but can also be used with any other scenegraph/lib if you want to implement the graphic part). Unfortunately (for you) it won't export, just import. Personally I don't see why an engine (like Xith3D) should export some graphic file format at all (except if there's a 3D modeler part of the package, which may be a good idea (I said "may")).

SO as I and Marvin said you'd better use Blender.

If you still awnt to go with Whoola COLLADA : you'll need Triangulation : http://www.cs.unc.edu/~dm/CODE/GEM/chapter.html

And triangles element have only one p element.
