Detailed Description
Terrain provides a framework for loosely coupling height field data with height rendering algorithms. This allows TerrainTechnique's to be plugged in at runtime.Member Typedef Documentation

| osgTerrain::Terrain::Terrain | ( | const Terrain & | , | |
| const osg::CopyOp & | copyop = osg::CopyOp::SHALLOW_COPY | |||

Member Function Documentation
| osgTerrain::Terrain::META_Node | ( | osgTerrain | , | |
| Terrain | ||||
| ) |
| virtual void osgTerrain::Terrain::traverse | ( | osg::NodeVisitor & | ) | [virtual] |
Traverse downwards : calls children's accept method with NodeVisitor.
Reimplemented from osg::Group.
| void osgTerrain::Terrain::setSampleRatio | ( | float | ratio | ) | [inline] |
Set the sample ratio hint that TerrainTile should use when building geometry. Defaults to 1.0, which means use all original sample points.
| float osgTerrain::Terrain::getSampleRatio | ( | ) | const [inline] |
Get the sample ratio hint.
| TerrainTile* osgTerrain::Terrain::getTile | ( | const TileID & | tileID | ) |
Get the TerrainTile for a given TileID.
| const TerrainTile* osgTerrain::Terrain::getTile | ( | const TileID & | tileID | ) | const |
Get the const TerrainTile for a given TileID.
| void osgTerrain::Terrain::registerTerrainTile | ( | TerrainTile * | tile | ) | [protected] |
| void osgTerrain::Terrain::unregisterTerrainTile | ( | TerrainTile * | tile | ) | [protected] |
