Functions
int	Rast3d_write_tile (RASTER3D_Map *map, int tileIndex, const void *tile, int type)
	Writes tile with index tileIndex to the file corresponding to map. It is assumed that the cells in tile are of type which must be one of FCELL_TYPE and DCELL_TYPE. The actual type used to write the tile depends on the type specified at the time when map is initialized. A tile can only be written once. Subsequent attempts to write the same tile are ignored.

Function Documentation

Rast3d_flush_tile()

int Rast3d_flush_tile	(	RASTER3D_Map *	map,
		int	tileIndex
	)

Writes the tile with tileIndex to the file corresponding to map and removes the tile from the cache (in non-cache mode the buffer provided by the map-structure is written). If this tile has already been written before the write request is ignored. If the tile was never referred to before the invocation of Rast3d_flush_tile, a tile filled with NULL-values is written.

Parameters

map
tileIndex

Returns

1 ... if successful, 0 ... otherwise.

		int	xMin,
		int	yMin,
		int	zMin,
		int	xMax,
		int	yMax,
		int	zMax
	)

Writes the tiles with tile-coordinates contained in the axis-parallel cube with vertices (xMin, yMin, zMin) and (xMax, yMax, zMax). Tiles which are not stored in the cache are written as NULL-tiles. Write attempts for tiles which have already been written earlier are ignored.

		int	xMin,
		int	yMin,
		int	zMin,
		int	xMax,

		int	zMax
	)

Writes those tiles for which every cell has coordinate contained in the axis-parallel cube defined by the vertices with cell-coordinates (xMin, yMin, zMin) and (xMax, yMax, zMax). Tiles which are not stored in the cache are written as NULL-tiles. Write attempts for tiles which have already been written earlier are ignored.

Rast3d_write_tile()

int Rast3d_write_tile	(	RASTER3D_Map *	map,

The actual type used to write the tile depends on the type specified at the time when map is initialized. A tile can only be written once. Subsequent attempts to write the same tile are ignored.

Parameters
