I have been working on rendering of .dae files (XNA engine) by extracting .kmz files exported from Google Sketchup ver 6 and 7.
To accomplish this, processing data from <library_materials>, <library_effects> and <library_geometries> xml sections of a .dae file were sufficient to render a basic 3D model and <library_nodes>, <library_cameras> and <library_visual_scenes> have been ignored completely.
I have come across a google sketchup exported complex .kmz for which the .dae file does not render properly. It has been observed that .dae file contained child nodes <node><node> (groups) which refer to the meshes under <library_geometries>.
- How do we deal with the child nodes for rendering a basic 3D Model?
- Is there any relation between child node groups and mesh formation? Anything like repeated meshes for a group?
Your suggestions would be much appreciated.
