VPB LOG GeoExtent_Constraint
Reply with quote

Hi,

Everybody,I got some problem in the terrainmodeling by VPB.
1,I find many code like"log(osg::INFO,"SourceData::readShapeFile")" in the VPB's source,I wonder if i can output the log's data into a file when I use the osgDEM,so I can track what's done during the modeling process.
2,If I want to get the terrain model of just exactly the area in a polygon,for example,300m within the centerline of a highway,while the part that is outside of the polygon is not necessary and is not generated to improve the rendering performance. How can I achieve it,just set the DEM value to NoData for the useless area,or rewrite some important function in the DestinationTile or somewhere.

3,are them compatible between the VPB's latest version and OSG3.0.


Thank you All!Any suggestion is appreciated!

Cheers,
Lei
