Member Data Documentation

effector_func Mercator::TerrainMod::m_function
protected

Function used to apply this mod to existing points.

This makes the basic mods much more powerful without the need for extra classes. It completely obsoletes AdjustTerrainMod, which is now the same as LevelTerrainMod with this function changed from set() to sum()

Referenced by Mercator::LevelTerrainMod< Shape >::apply(), and Mercator::SlopeTerrainMod< Shape >::apply().
