Hi all....
I'm working in a osg::NodeVisitor to see TerrainTiles that are Currently
Active, Which I thought were the visible tiles... when I zoom in to the DB and
look at hi rez tiles, then zoom out again to see lo rez tiles, the tile
printout information always the highest level for that location.. and while I
can see the mesh in the window is a low res tile, or page or cell etc... my
printout always shows the highest LOD data.
Here is the code
virtual void apply(osgTerrain::TerrainTile& tile)
{
osgTerrain::TerrainTile* TT =
dynamic_cast<osgTerrain::TerrainTile*>(&tile);
osgTerrain::TileID tid = tile.getTileID();
for (int i=0;i< tid.level; i++)
std::cout << " | ";
std::cout << " Tile X "<< tid.x << " Tile Y "<< tid.y << " Tile
level " << tid.level << std::endl;
}
virtual void apply(osg::Group& group)
{
static int depth = 0;
std::cout<<" " << depth << " "<< &group << "G "<< group.className()
<<" has " <<group.getNumChildren()<< "C" << std::endl;
// distinguish a tile from other groups
osgTerrain::TerrainTile* tile =
dynamic_cast<osgTerrain::TerrainTile*>(&group);
if (tile)
{
apply(*tile);
}
else
{
depth++;
traverse(group);
depth--;
}
}
...
Thank you!
Cheers,
lawrence
