Torsten, The changes you suggest are surely doable and we should take those into the "TODO" -list. However, I would not yet pursue in changing the code related to this since it would affect the deliverables and also documents. I am uncertain how those changes would be incorporated at this point, given that we we have had some trouble in finalizing the documentation in the past. Maybe this could go (among other things) to the task list of Fi-Core enhancements for GIS. - j On Thu, Jun 26, 2014 at 3:42 PM, Torsten Spieldenner < torsten.spieldenner at dfki.de> wrote: > Hello, > > as mentioned in the call yesterday, I think the delivery of the XML3D > ground geometry as reply from GIS-Data-Provider could be improved based on > the new asset instancing technique of XML3D. > > Currently, the result is returned as .xml3d - file, that contains the > geometry in a format similar to that: > > <group> > <mesh> > ..... // indices, positions, texcoords ... // /// > </mesh> > </group> > > Client handles the request by copying this reply into the client's > xml3d-node.
