I'm new to FME so I hope I didn't miss a tutorial or a manual somewhere ;)
In a few words I'd like to export a CityGML to KML/Collada files in order to load these in GoogleEarth and other 3D clients. In details :
<= Input : A CityGML containing 300 buildings referencing textures. The general structure of my CityGML is :
<CityModel> <Building> <BuildingPart> <Appearance> <SurfaceDataMember>
... </Appearance> <RoofSurface>
...
<WallSurface>
... </BuildingPart> </Building>
... </CityModel>
=> Output : Idealy I'd like to generate a collection of KMZ files containing KML + Collada + Textures. Each KMZ file would represent a portion (a tile) of the original CityGML file.
My question : Where to start ? :)
What I've already done :
1) I've been able to load my CityGML file in FME. A certain number of Feature Type were imported (Building, BuildingPart, WallSurface, RoofSurface,CityModel).
2) I've been able to define a Collada writer and translate my data (by the way it seems 8Gb of ram wasn't enough). As a result I obtained a .dae file for each featureType ... which is not really what I'm trying to achieve => I thought of getting a Collada file containing each building with complete geometry (roofs+walls) as a first step.
So : Are there any example FME project or tutorials that might help me to achieve this kind of transformation ? At least, is there a way to iterate through the building list, get roofs+ walls and concatenate the geometry to produce a Collada containing the list of all building geometries ?
Hope it's clear enough,
Thanx in advance
Emmanuel
