C++ (Cpp) Tile::ancestorChangedElevationData Examples

Example #1

File: Tile.cpp Project: AeroGlass/g3m

void Tile::ancestorChangedElevationData(Tile* ancestor){

  if (ancestor->getLevel() > _elevationDataLevel){
    ElevationData* subView = createElevationDataSubviewFromAncestor(ancestor);
    if (subView != NULL){
      setElevationData(subView, ancestor->getLevel());
    }
  }

  if (_subtiles != NULL) {
    const int subtilesSize = _subtiles->size();
    for (int i = 0; i < subtilesSize; i++) {
      Tile* subtile = _subtiles->at(i);
      subtile->ancestorChangedElevationData(this);
    }
  }
}

Example #2

File: Tile.cpp Project: AeroGlass/g3m

void Tile::setElevationData(ElevationData* ed, int level){
  if (_elevationDataLevel < level){

    if (_elevationData != NULL){
      delete _elevationData;
    }

    _elevationData = ed;

    _mustActualizeMeshDueToNewElevationData = true;

    //If the elevation belongs to tile's level, we notify the sub-tree
    if (isElevationDataSolved()){

        const int subtilesSize = _subtiles->size();
        for (int i = 0; i < subtilesSize; i++) {
