Hi everyone.
I want a line on the terrain surface, while my terrain data is a paged
lod database. when I use osgSim::ElevationSlice, The
visitor(osgUtil::IntersectionVisitor) always go to the max valid level of
the terrain detail. so when i draw the line of ElevationSlice's result, the
line is not exactly on the surface of terrain.
Is there any visitor like cullvisitor can go to current valid lod level?
and then I can draw the ElevationSlice's result line on the surface always.
best wishes.
