Heighway dragon curve. A dragon curve is any member of a family of self-similar fractal curves, which can be approximated by recursive methods such as Lindenmayer systems.The dragon curve is probably most commonly thought of as the shape that is generated from repeatedly folding a strip of paper in half, although there are other curves that are called dragon curves that are generated differently.
As a houseplant it is rare in commerce, with the unimproved species, and the cultivars 'Dragonscale', 'Green Dragon' and 'Silver Dragon'. [ 2 ] [ 3 ] [ 4 ] References
Many of Kamiya's origami designs are complex; his Divine Dragon and Ancient Dragon models require around 275 steps each and need to be made from at least 50 cm squares of thin paper or foil. One of his notable designs is the Ryu-Zin 3.5, an elaborate dragon covered with scales and having feelers, claws, and horns.
Opening out each fold to create a right-angled corner (or, equivalently, making a sequence of left and right turns through a regular grid, following the pattern of the paperfolding sequence) produces a sequence of polygonal chains that approaches the dragon curve fractal: [1]
The Nobbi Dragon is a part of the Diporiphora genus which has 21 species which is distinct from other Agamidae species due to their climbing ability and morphological attributes. [3] [2] Like other reptiles the Nobbi Dragon reproduces sexual and is a oviparous animal laying eggs and embryo's developing inside the eggs. [4]
While reptile scales use a sophisticated naming system (see figures), there has been a certain confusion because of synonymous names. For instance, the ventral scales are often called ventrals but gastrosteges is common in the older literature. In more recent publications they are often abbreviated as VSR (for ventral scale rows) or simply V. [4]
Dragonology: The Complete Book of Dragons was followed up by a number of additional Dragonology books (and other merchandise), including Tracking and Taming Dragons: Vol. 1 [4] and Vol. 2, [5] Dr. Ernest Drake's Dragonology Handbook: A Practical Course in Dragons, [6] and Drake's Comprehensive Compendium of Dragonology [7] among others.
