Functions
void *	Rast3d_open_cell_old_no_header (const char *name, const char *mapset)
void *	Rast3d_open_cell_old (const char *name, const char *mapset, RASTER3D_Region *window, int typeIntern, int cache)
	Opens existing g3d-file name in mapset. Tiles are stored in memory with type which must be any 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. window sets the window-region for the map. It is either a pointer to a window structure or RASTER3D_DEFAULT_WINDOW, which uses the window stored at initialization time or set via Rast3d_set_window () (cf.{g3d:G3d.setWindow}). To modify the window for the map after it has already been opened use Rast3d_set_window_map () (cf.{g3d:G3d.setWindowMap}). Returns a pointer to the cell structure ... if successful, NULL ... otherwise. More...
void *	Rast3d_open_cell_new (const char *name, int typeIntern, int cache, RASTER3D_Region *region)
	Opens new g3d-file with name in the current mapset. Tiles are stored in memory with type 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.

Rast3d_open_cell_new()

void* Rast3d_open_cell_new	(	const char *	name,
		int	typeIntern,
		int	cache,
		RASTER3D_Region *	region
	)

Opens new g3d-file with name in the current mapset. Tiles are stored in memory with type 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. Returns a pointer to the cell structure ... if successful, NULL ... otherwise.

Rast3d_open_cell_old()

void* Rast3d_open_cell_old	(	const char *	name,
		const char *	mapset,
		RASTER3D_Region *	window,
		int	typeIntern,
		int	cache
	)

Opens existing g3d-file name in mapset. Tiles are stored in memory with type which must be any 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. window sets the window-region for the map. It is either a pointer to a window structure or RASTER3D_DEFAULT_WINDOW, which uses the window stored at initialization time or set via Rast3d_set_window () (cf.{g3d:G3d.setWindow}). To modify the window for the map after it has already been opened use Rast3d_set_window_map () (cf.{g3d:G3d.setWindowMap}). Returns a pointer to the cell structure ... if successful, NULL ... otherwise.
