Wonderland content creation
One of the key goals of Wonderland is to allow users to create their own content for the world so you can create and decorate your own team rooms, meeting places (or any other part of the world). Initially we will rely on external 3D modeling tools to create content with an eye to also supporting in world content creation in the future.
In terms of raw geometry we could support any tool which has a Java 3D loader, however in many cases we will have to add meta data to the geometry so that they can be manipulated correctly in world. We don't want to restrict content creation to a single app so are looking to create support for the widest possible range of tools. Our initial work for the prototype/demo uses the x3d format with data exported from Maya. All well and good if you can drive such a powerful tool (and afford the license). I'd also like to ensure that we have full support for open source tools such as Blender, and simple tools (for those like me who are artistically challenged) like Sketchup.
There is already a loader path for Blender into Java 3D, but I'm not aware of one for Sketchup. The KML format that Sketchup exports for Google Earth is documented here http://earth.google.com/kml/kml_tags_21.html anyone fancy writing a Java 3D loader for this format ? Once we have the basic loader we can worry about the extra meta data later.
