(1) handle hierarchical nodes in the visual scene
(2) handle the <triangle> element of geometries. This was done the lazy way: convert <triangles> to <polylist> and call the function that was already there for handling <polylist>
Sample code:
var parser = new OpenMetaverse.ImportExport.ColladaLoader();
var prims = parser.Load(o.FileName);
if (prims != null && prims.Count > 0)
{
var uploader = new OpenMetaverse.ImportExport.ModelUploader(client, prims);
uploader.PrepareUpload();
}
Note that PrepareUpload performs the upload as well in this initial stage.
TODO:
* Image upload
* Support for quads in addition to triangles
