示例1: apply
virtual void apply(osg::PagedLOD& node)
{
//The PagedLOD node will contain two filenames, the first is empty and is the actual geometry of the
//tile and the second is the filename of the next tile.
if (node.getNumFileNames() > 1)
{
//Get the child filename
const std::string &filename = node.getFileName(1);
if (osgEarth::Registry::instance()->isBlacklisted(filename))
{
//If the tile is blacklisted, we set the actual geometry, child 0, to always display
//and the second child to never display
node.setRange(0, 0, FLT_MAX);
node.setRange(1, FLT_MAX, FLT_MAX);
}
else
{
//If the child is not blacklisted, it is possible that it could have been blacklisted previously so reset the
//ranges of both the first and second children. This gives the second child another
//chance to be traversed in case a layer was added that might have data.
osg::ref_ptr< MapNode::TileRangeData > ranges = static_cast< MapNode::TileRangeData* >(node.getUserData());
if (ranges)
{
node.setRange(0, ranges->_minRange, ranges->_maxRange);
node.setRange(1, 0, ranges->_minRange);
}
}
}
traverse(node);
