Menu: Files->Export->KML...
With this option it is possible to write Kml files of Google Earth, in xml format (with .kml or .mkz extension for compressed files)
This exporter is implemented as a Tcl plugin.
To properly georeference the mesh the current coordinates could be transformed to geographical coordinates declaring the current coordinate system (e.g. UTM zone and hemisphere)
Postprocess meshes and results are exported in a vectorial way. It is possible also export coloured results as a collection of images.
