Could you give me a description of T3D (and may be CNV) file format? I mean a description of internal structure in whatever language you have.
The reason I'm asking that I'm now working on O-GPS Center service (www.o-gps-center.ru
) for tracking o-events. We want to show live tracking on a 3D map. The idea is to start with to use CatchingFeatures to convert maps into 3D format and then read the produced file and visualize by means of WebGL. Knowing the description of your file format would save us some time at the beginning.
