void* G3d_openCellNew	(	const char *	name,
		int	typeIntern,
		int	cache,
		G3D_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 G3D_TILE_SAME_AS_FILE. cache specifies the cache-mode used and must be either G3D_NO_CACHE, G3D_USE_CACHE_DEFAULT, G3D_USE_CACHE_X, G3D_USE_CACHE_Y, G3D_USE_CACHE_Z, G3D_USE_CACHE_XY, G3D_USE_CACHE_XZ, G3D_USE_CACHE_YZ, G3D_USE_CACHE_XYZ, the result of G3d_cacheSizeEncode () (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.
