Class GeographicTilingScheme

java.lang.Object

com.gaia3d.util.geographic.GeographicTilingScheme

public class GeographicTilingScheme
extends Object

GeographicTilingScheme implements a tiling scheme based on geographic coordinates (latitude and longitude). It divides the world into tiles at various levels of detail.

geographicToCartesian

public org.joml.Vector3d geographicToCartesian(org.joml.Vector3d geographic)

positionToTile

public TileCoordinate positionToTile(int level,
 double latitude,

(lat, lon) 좌표를 타일 좌표(level, x, y)로 변환한다. y=0 이 북쪽, y 증가할수록 남쪽으로 내려간다.

Parameters:

level - tile level (0 ~ maxLevel)

latitude - 위도(-90 ~ 90)

longitude - 경도(-180 ~ 180)

tileToBounds

public GaiaRectangle tileToBounds(TileCoordinate tile)

주어진 타일(level, x, y)의 위경도 경계를 반환한다. y=0 이 북쪽, y 증가할수록 남쪽으로 내려간다.

tileToBounds

public GaiaRectangle tileToBounds(int level,
 int x,
 int y)

getNumberOfXTilesAtLevel

public int getNumberOfXTilesAtLevel(int level)

주어진 level에서 X 방향 타일 개수 (경도 방향).

getNumberOfYTilesAtLevel

public int getNumberOfYTilesAtLevel(int level)

주어진 level에서 Y 방향 타일 개수 (위도 방향).
