MercatorTextureTile

public MercatorTextureTile(MercatorSector mercatorSector,
                           Level level,
                           int row,

Method Detail

createSubTiles

public MercatorTextureTile[] createSubTiles(Level nextLevel)

Description copied from class: TextureTile

Splits this texture tile into four tiles; one for each sub quadrant of this texture tile. This attempts to retrieve each sub tile from the texture tile cache. This calls TextureTile.createSubTile(gov.nasa.worldwind.geom.Sector, gov.nasa.worldwind.util.Level, int, int) to create sub tiles not found in the cache.

Overrides:

createSubTiles in class TextureTile

Parameters:

nextLevel - the level for the sub tiles.

Returns:

a four-element array containing this texture tile's sub tiles.

getMercatorSector

public MercatorSector getMercatorSector()

getTileFromMemoryCache

protected MercatorTextureTile getTileFromMemoryCache(TileKey tileKey)

Overrides:

getTileFromMemoryCache in class TextureTile
