Unlike Euclidean shapes this object has detail at all levels. If it is not there too, then contact us to info fractals in computer graphics pdf download. This is the idea of self similarity. This applies equally well to the circumference of a circle, a curve, or the boundary of any object.
As you can see the line is broken into 4 smaller lines. In two dimensions, ff the linear dimensions of a rectangle for example is doubled then the characteristic size, the area, increases by a factor of 4.
Where N is the number of small pieces that go into the larger one, S is the scale to which the smaller pieces compare to the larger one and D is the dimension.
Now solve for D in the previous equation; we find: Note that with both fractals in computer graphics pdf download it is possible to create the image at any scale.
A technique exists by which the resulting form after an infinite number of iterations can fracctals derived. Hausdorff-Besicovitch Fractal Dimension To understand the second definition we need to be able to understand the fractal dimension. We now have the tools to be able to calculate the dimension.
So now there are 12 edges and 12 points. Search in the document preview. By looking at this we begin to see a pattern: Animals, plants, rocks, crystals and liquids all exhibit fractal properties and self similarity. One of the important characteristics of L systems is that only a small amount of information is required to represent very complex objects.

The closer we look the more detail we see. We will see the overall theme of repeating leaves.
Euclidean Geometry is the geometry of lines, planes, circles etc. That one number could be the distance from the start of the line. Self Similarity So what do these mathematical curiosities have to do with the real world? The curve is infinitely detailed. Instead of storing the geometry of the very complex object just the IFS generator needs to be stored and fractala fractals in computer graphics pdf download can be generated when required.
Computer graphics interactive workshop for two dimensional fractals.
Thus the limiting curve is of infinite length and indeed the length between any two points of the curve is infinite. However, people soon discovered that they could draw or at least begin to draw certain curves and surfaces that could not be described by the classical geometry.
Simpleminded example of 0L system A string of characters fractals in computer graphics pdf download is rewritten on each iteration according fractals in computer graphics pdf download some replacement rules. What is interesting it that the program to generate this image is only a few lines long.
This relationship between dimension D, linear scaling L and the resulting increase in size S can be generalized and written as This is just telling us mathematically what we know from everyday experience.

As in the case of L systems, if the IFS code for a desired image can be determined by something called the Collage theorem then large data compression ratios fractlas be achieved.
If we say that each line is of length 1, then the total length of the curve is 3. Access your Docsity account. Sign in via social Sign up with Facebook Sign up with Google.
