  European dragon - Wikipedia, the free encyclopedia
The dragon of the modern period is typically depicted as a huge fire-breathing, scaly and horned dinosaur-like creature, with leathery wings, with four legs and a long muscular tail.
The female dragon represents harsh weather and is the destroyer of crops, the hater of mankind, and is locked in a never ending battle with her brother.
The red dragon is unmistakably linked with the Welsh and it is believed the white dragon refers to the English, but some have speculated that it originates from Arthurian Legend where Merlin had a vision of the red dragon (representing Uther Pendragon) and the white dragon (representing Vortigen) in battle.

 Dragon curve - Wikipedia, the free encyclopedia
A dragon curve is the generic name for a member of a family of self similar fractal curves, which can be approximated by recursive methods such as Lindenmayer systems.
The Heighway dragon (also known as the Harter-Heighway dragon or the Jurassic Park dragon) was first investigated by NASA physicists John Heighway, Bruce Banks, and William Harter.
The Lévy C curve is sometimes known as the Lévy dragon.

 Curve
This definition of curve captures our intuitive notion of a curve as a connected, smooth figure that is "like" a line; although it also includes figures that are not called curves in common usage.
For example, a mathematical curve can have any number of "kinks" or corners, since these have no effect on whether or not the resulting figure can be "stretched" and smoothed into a straight line; this is roughly the meaning of "can be continuously mapped".
Some extreme examples of "kinky" curves are the fractal Koch curve and the dragon curve[?].

 Davis Associates, Inc. on Dragon curves
The classical Dragon curve, discovered by physicist John E. Heighway, is the curve that results when a sheet of paper is folded in half, then folded in half again, and again, etc. and is then unfolded in such a way that each crease created by the folding process is opened out into a 90-degree angle.
The term "classical" Dragon curve refers to the curve that results when the original folds (as opposed to the more numerous creases that are created) are all in the same direction.
Second, and perhaps most remarkable, four copies of the Dragon curve, each starting from the origin in one of the four orthogonal directions (e.g., east, south, west and north), never intersect each other and, in fact, are lattice-space filling (interlocking).

 The Boundary of Dragon Curve   (Site not responding. Last check: 2007-11-06)
The dragon curve is a space filling curve with dimension 2 which originally came from the repeated folding of a long stripe of paper [4] in the same direction.
To alleviate this neglect, it is the purpose of this paper is to study the boundary of dragon curve.
To produce the entire boundary of the dragon curve, four similar pieces of the border, generated by the above algorithms, have to be arranged as shown in Figure 8.

 Fractals: Heighway Curve
Although the construction of this curve is quite simple, its fascinating properties have stimulate a lot of works in different fields of mathmatics.
While three methods were described for the construction of the Dragon curve, the discussion will be limited to the method used originally by Heighway.
The self-similarity N and r values are derived from the construction of the curve using the triangle method.

The Dragon curve (the paperfolding sequence) was discovered by physicist John Heighway and was described by Martin Gardner in 1978.
It turns out, that the Dragon curve is related to the sigma-sequence, that was used by Evdokimov in 1968 in order to construct chains of maximal length in the n-dimensional unit cube.
The Peano curve was studied by the Italian mathematician Giuseppe Peano in 1890 as an example of a continuous space filling curve.

 Paper-Folding-Fractals (construct)
This particular pattern is commonly called "The Dragon" and was popularized in the film "Jurassic Park".
Level 3 of The Dragon is produced by folding the paper in-half 3 times to the left, and opening it up to eight sides and seven right angles (figure 3a).
The first half of level 4 is an exact copy of level 3 (except each side in level 4 is half the length of each side in level 3).

 FRACTINT L-systems Spacefilling Curves   (Site not responding. Last check: 2007-11-06)
This curve looks like a church on which a mural is painted reminiscent of the painting of God giving life to Adam.
All of the spacefilling curves described so far revisit certain points, but there are many spacefilling curves which never revisit any points.
This is to insure that when FRACTINT is drawing the Cross it is oriented the same way after drawing X or Y as it was when it began drawing X or Y. This is the safe thing to do if you don't understand how the orientation may affect the outcome of your L-system.

 Paper Folding   (Site not responding. Last check: 2007-11-06)
If a large sheet of paper is folded in half, then in half again, etc, with all the folds parallel, then opened up flat, there are a series of parallel creases, some pointing up and some down, dividing the paper into fractions of the original length.
Finally the bottom edge of the paper is viewed end-on to see the dragon curve.
Output will consist of a series of dragon curves, one for each value of N in the input.

 Heighway Dragon
The construction of the Lévy dragon and the Heighway dragon are very similar.
For the Lévy dragon, both are placed towards the "outside"; for the Heighway dragon, one is placed pointing out while the other is placed pointing in.
Then A is a continuous function from the unit interval to the space of compact sets with the Hausdorff topology, with A(0) equal to the Lévy dragon and A(1) equal to the Heighway dragon.

We begin with a long strip of paper placed on the table and fold it at the middle of it in the same direction repeatedly as shown.
At around the 12th generation folding, a faint impression of Chinese dragons begins to emerge, which then becomes more distinctive at the 13th and 14th generations.
This had led its discover, J.E. Heighway, to coin the word, Dragon curve, for the meandering paper strip folding.

Mandelbrot [Man83] calls this the Harter-Heighway dragon; an extensive discussion of its properties can be found in [Gar67, DK70].
There is a natural dynamical process of ``folding'' at work in the creation of the dragon curves.
Following the curve from beginning to end, each turn is either to the left or to the right.

Three years later, as my was doing some Spring cleaning on my account, getting rid of old files, I stumbled across this Dragon Curve program and decided to have another look at it.
On my way to understand the mysteries of this Dragon Curve program that I had, I've encountered a number of L-system equations.
This code looks a little more complicated than the Dragon Curve before, but it's mostly because of colors and because it's made generic to work with many different equations and coloring schemes.

 Lévy Dragon Tiles the Plane
Moreover, it has the very curious property that, if [the dragon curve] were materialized, one could tile the plane with it, i.e., one can cover the plane with identical copies of this curve such that no two copies intersect, and such that no space is left uncovered.
This was the triangle used in the description of of the construction of the Levy dragon.
Applying the first step of the Lévy dragon construction to each of these triangles produces four congruent copies of L1 that still cover the unit square (see Figure 1).

 Dragon Curve   (Site not responding. Last check: 2007-11-06)
Beware, drawing a Dragon Curve of degree 10 or above can be real slow (the canvas has to render 4 * 2^^degree lines segments).
The only thing was when I ran the Dragon Curve with a Degree setting of 12 my computer was nonresponsive for 10 minutes.
So the only way to make the code more responsive would be to draw the dragon curve in smaller pieces and have some kind of GUI refresh in between segments.

MacSpeech Inc's president says that his company will stay the course despite the surprise announcement at WWDC last week that Dragon Systems will be porting their popular PC continuous speech recognition program, NaturallySpeaking, to the Mac Platform, with Apple's blessing and fanfare.
This news had to have been a bitter slap in the face for the folks at MacSpeech, who have been the only developers working on a Mac dictation program since Dragon unceremoniously dumped Mac support last year when they terminated development and support of their long-in-the-tooth PowerSecretary for the Mac.
Dragon's NaturallySpeaking is highly respected, premium dictation software, without question.
