Lamzdeliai and twisted off of the wood. The blowing end is closed off with a stopper made from the wood, with one side cut off. At the place where the stopper ends, a whistle hole is cut into the bark, and one end of the hole is bent slightly inwards. Three to six finger holes are cut in the pipe. Wooden pipes are made of ash or linden wood. The bark is removed, and the instrument is hollowed out by burning, drilling or carving. The blowing hole, whistle hole and finger holes are made in the same way as for the
Esri TIN points ([1, # of points]). The separators are -1 (0xFFFFFFFF) and zero (0). If the TIN is constructed using superpoints (usually the first 4 points), thul.adf lists the indices of these points and then -1 (0xFFFFFFFF). After the separator follows one or more lists of indices that form bounding polygons (outer boundaries) and maybe holes (inner boundaries). These lists are separated by zero (0) values. If the TIN does not contain superpoints, thul.adf starts with the -1 (0xFFFFFFFF) separator, which is followed by one or more lists of indices that form bounding polygons (outer boundaries) and maybe holes (inner boundaries).
