Hi, EveryOne.
I am using the VPB and osgGIS. My step as follows: first use the image
and dem file of a small region to generate terrain models by VPB , and then
use the shp file to generate vector shape models, finally, in my
application, I set the vector shape models' root as overlay to the terrain
models' root.
The final display effect has a problem that the generated texture of
overlay cannot change it's resolution.So when I zoom in the viewer, the
resampling effect is ugly.
And there is anthoer question that I want the blend effect between
overlay texture and the real terrain texture , but I can not find the
interface in class osgSim::OverlayNode. If I don't use the OverlayNode and
just blend the terrain models and the vector shape models, then the depth
setting will be a question.
I'm waiting your reply, Thanks.
