I'm not sure I understand the idea of the new option. The heights templates
[1] do exactly what we want to do, right? In fact, I just checked that with
Geoserver 2.3.0 we obtain the results we expect for points (I'm attaching
two screenshots with and without extrusion); but polygons don't extrude in
Geoserver 2.3.0 (we cannot obtain the results shown in [1]). In Geoserver
2.4.0 we have the opposite, we can extrude polygons (as in [1]) but we
cannot "extrude" our points (as in my screenshots with 2.3.0).
Does this mean that this is a different issue than [2]?
Regards,
Víctor.
P.D: The URLs I used for the screenshots are:
http://localhost:8080/geoserver/wms/reflect?layers=sde:test&format=application/vnd.google-earth.kml%2Bxml&format_options=extrude:false
http://localhost:8080/geoserver/wms/reflect?layers=sde:test&format=application/vnd.google-earth.kml%2Bxml&format_options=extrude:true
