Functions
void *	Rast3d_open_new_param (const char *name, int typeIntern, int cache, RASTER3D_Region *region, int type, int compression, int precision, int tileX, int tileY, int tileZ)
	Opens new g3d-file with name in the current mapset. Tiles are stored in memory with typeIntern which must be one of FCELL_TYPE, DCELL_TYPE, or RASTER3D_TILE_SAME_AS_FILE. cache specifies the cache-mode used and must be either RASTER3D_NO_CACHE, RASTER3D_USE_CACHE_DEFAULT, RASTER3D_USE_CACHE_X, RASTER3D_USE_CACHE_Y, RASTER3D_USE_CACHE_Z, RASTER3D_USE_CACHE_XY, RASTER3D_USE_CACHE_XZ, RASTER3D_USE_CACHE_YZ, RASTER3D_USE_CACHE_XYZ, the result of Rast3d_cache_size_encode () (cf.{g3d:G3d.cacheSizeEncode}), or any positive integer which specifies the number of tiles buffered in the cache. region specifies the 3d region. The map is created using the type which must be of FCELL_TYPE or DCELL_TYPE. The methods for compression can be specified LZW or RLE. The digits of the floating point mantissa can be specified. In case of FCELL_TYPE 0-23 and 0-52 in case of DCELL_TYPE. The number cells in X, Y and Z direction defines the size of each tile. Returns a pointer to the cell structure ... if successful, NULL ... otherwise. More...
void *	Rast3d_open_new_opt_tile_size (const char *name, int cache, RASTER3D_Region *region, int type, int maxSize)
	Opens new g3d-file with name in the current mapset. This method tries to compute optimal tile size based on the number of rows, cols and depths and the maximum allowed tile size in KB. Tiles are stored in memory using RASTER3D_TILE_SAME_AS_FILE method. cache specifies the cache-mode used and must be either RASTER3D_NO_CACHE, RASTER3D_USE_CACHE_DEFAULT, RASTER3D_USE_CACHE_X, RASTER3D_USE_CACHE_Y, RASTER3D_USE_CACHE_Z, RASTER3D_USE_CACHE_XY, RASTER3D_USE_CACHE_XZ, RASTER3D_USE_CACHE_YZ, RASTER3D_USE_CACHE_XYZ, the result of Rast3d_cache_size_encode () (cf.{g3d:G3d.cacheSizeEncode}), or any positive integer which specifies the number of tiles buffered in the cache. region specifies the 3d region. The map is created using the type which must be of FCELL_TYPE or DCELL_TYPE. Returns a pointer to the cell structure ... if successful, NULL ... otherwise. More...

Rast3d_open_new_opt_tile_size()

void* Rast3d_open_new_opt_tile_size	(	const char *	name,
		int	cache,
		RASTER3D_Region *	region,
		int	type,
		int	maxSize
	)

Opens new g3d-file with name in the current mapset. This method tries to compute optimal tile size based on the number of rows, cols and depths and the maximum allowed tile size in KB. Tiles are stored in memory using RASTER3D_TILE_SAME_AS_FILE method. cache specifies the cache-mode used and must be either RASTER3D_NO_CACHE, RASTER3D_USE_CACHE_DEFAULT, RASTER3D_USE_CACHE_X, RASTER3D_USE_CACHE_Y, RASTER3D_USE_CACHE_Z, RASTER3D_USE_CACHE_XY, RASTER3D_USE_CACHE_XZ, RASTER3D_USE_CACHE_YZ, RASTER3D_USE_CACHE_XYZ, the result of Rast3d_cache_size_encode () (cf.{g3d:G3d.cacheSizeEncode}), or any positive integer which specifies the number of tiles buffered in the cache. region specifies the 3d region. The map is created using the type which must be of FCELL_TYPE or DCELL_TYPE. Returns a pointer to the cell structure ... if successful, NULL ... otherwise.

Parameters

name	The name of the map
cache	The type of the caching
region	The region of the map
type	The type of the map (FCELL_TYPE, or DCELL_TYPE)
maxSize	The maximum size of a tile in kilo bytes

Returns

Rast3d_open_new_param()

void* Rast3d_open_new_param	(	const char *	name,
		int	typeIntern,
		int	cache,
		RASTER3D_Region *	region,
		int	type,
		int	compression,
		int	precision,
		int	tileX,
		int	tileY,
		int	tileZ
	)

Opens new g3d-file with name in the current mapset. Tiles are stored in memory with typeIntern which must be one of FCELL_TYPE, DCELL_TYPE, or RASTER3D_TILE_SAME_AS_FILE. cache specifies the cache-mode used and must be either RASTER3D_NO_CACHE, RASTER3D_USE_CACHE_DEFAULT, RASTER3D_USE_CACHE_X, RASTER3D_USE_CACHE_Y, RASTER3D_USE_CACHE_Z, RASTER3D_USE_CACHE_XY, RASTER3D_USE_CACHE_XZ, RASTER3D_USE_CACHE_YZ, RASTER3D_USE_CACHE_XYZ, the result of Rast3d_cache_size_encode () (cf.{g3d:G3d.cacheSizeEncode}), or any positive integer which specifies the number of tiles buffered in the cache. region specifies the 3d region. The map is created using the type which must be of FCELL_TYPE or DCELL_TYPE. The methods for compression can be specified LZW or RLE. The digits of the floating point mantissa can be specified. In case of FCELL_TYPE 0-23 and 0-52 in case of DCELL_TYPE. The number cells in X, Y and Z direction defines the size of each tile. Returns a pointer to the cell structure ... if successful, NULL ... otherwise.

Parameters

name	The name of the map
typeIntern	The internal storage type for in memory chached tiles
cache	The type of the caching
region	The region of the map
type	The type of the map (FCELL_TYPE, or DCELL_TYPE)
doLzw	Use the LZW compression algorithm
doRle	Use the Run-Length-Encoding algroithm for compression
precision	The precision used for the mantissa (0 - 52) or RASTER3D_MAX_PRECISION
tileX	The number of cells in X direction of a tile
tileY	The number of cells in Y direction of a tile
tileZ	The number of cells in Z direction of a tile
