The pattern of growing ivy is a pretty dense one. The leaves are the smallest elements within that pattern. Looking at the boundaries of it you can observe that ivy grows up in lines, each covered with leaves to the left and right side by turn. Through this the pattern has an appearance like an organic, random grid which is extendable in all directions. | The pattern of growing ivy is a pretty dense one.

The textile pattern on this chair has alternating vertical stripes. Some of these stripes are solid colors; others have patterns within them. Within the patterned stripes, a few have vertically stacked repeating elements. One set has a floral pattern sitting alone a line that resembles a sine wave. The floral pattern mirrors itself along the vertical axis. <br /> | |||
Color plays an important role in this textile pattern, as the plain black stripe is consistently placed between the two main alternating floral stripes. The black stripe contrasts sharply with the flowery pastels. | |||

[[File:Couchclothpatternsketch.jpg|thumb]] | |||
The pattern consists of very small strings. There are strings from the bottom to the top, and from left to right. Running from one side to another, every few millimeters a batch of strings runs over the crossing batch; after that it runs under the next one; over the one after - and so on. The batches running from left to right seem slightly thicker, forming a diversified web with the thinner ones from top to bottom. | |||

[[File:pattern rhombus.jpg|thumb|Click me!]] | |||
This pattern provides an illusion of depth due to use of simple 2D geometry (rhombus) with different shades that matches with our conception of how three-dimensional shapes must look like as soon as light is getting reflected off their surfaces from a specific angle. | |||

'''Asymmetric Balance!''' | |||
Asymmetry means without symmetry. That by itself has nothing to do with balance. It just means that there are no mirror images in a composition. The term, however, is usually used to describe a kind of balance that does not rely on symmetry: asymmetrical balance. There is no simple formula for achieving balance in asymmetrical balance (hence the term informal balance) so the designer must sense whether or not the composition is balanced. This is where your sense of balance really comes into play. | |||
<br><br> | |||
The composition either looks like it is balance or it does not. Where does your attention goes when you look at an image? If it seems to wander around more or less evenly, there is probably balance. If you seem to always come back to the same area, and that is not the center of the composition, then the balance is suspect. | |||
<br><br> | |||
One way to achieve balance that is almost a formula is to have more or less equally interesting things randomly distributed throughout the format. The effect is like confetti dropped on the area. There is balance because interest is evenly distributed, and there is unity. The problem is that everything is likely to seem too equal and hence too uniform. There is not enough variety and the design soon becomes boring. | |||

=== Textile on a Chair === | |||
[[File:Chair4.jpg]] | |||
To write the code for this pattern, you could set the background fill to (0). Then, there could be one main "for" structure, that continually repeats itself horizontally for the width of the window. Within this structure, there would be two sub "for" structures: A + B. The first (A) would feature the thicker main vertical set, and the second (B) would feature the thinner vertical set. Each set would be spaced roughly 1 inch (or <i>x</i> pixels) apart from each other. | |||
For each of the two vertical sets, we could create a stack of lines of varying thicknesses on top of each other. The bottom layer would have the heaviest weight, and the top layers the lightest weight. Within each of the two sets, each line would be centered, so that an equal part of the line appears from both sides as we move towards the center of the vertical set. As we approach the center of each set, we would have to create: | |||
A) The vertical sine wave mirrored upon itself vertically | |||
and | |||
B) The vertically stacked flowers | |||
For A), we create a trigonometic (sine wave) function. Perhaps we use another "for" structure with a float + sin() function. | |||
For B), we create yet another "for" structure, this time repeating an image along a vertical line. | |||

=== Textile on Pizza Chilino === | |||
[[File:Joey_Pizza.png|400px]] | |||
If we focus closely to this Chilio Pizza, we would see that the pizza contains with many layers. Each layer is decorated with vegetables, cheese and meat. However, the distance between each asset doesn't random itself, there is a hidden pattern which each edible lays far from each other by almost constant distance. | |||
To make sketch of this pizza, we would follow these processes below: | |||
1) Make a pizza flour base layer by drawing an ellipse and fill with cream or yellow color. <br/>'''Function''': ''ellipse()'',''fill()'' <br/><br/> | |||
2) Put a concentrate tomato sauce by drawing another layer on top of pizza flour, after that, fill red color. <br/>'''Function''': ''ellipse()'',''fill()'', ''pushMatrix()'', ''popMatrix()''<br/><br/> | |||
3) Create salamis() function by drawing ellipses and put little white spots on around salamis' surface. <br/>'''Function''': ''ellipse()'',''fill()'', ''point()'', ''random()'' <br/><br/> | |||
4) Spread salamis around the pizza with random() function BUT not further than pizza flour edge(2*PI*radian). Furthermore, we could use ''For loop'' or ''While loop'' iteration to identify a number of salamis we need. <br/>'''Function''': ''salamis()'', ''random()'',''constrain()'' <br/><br/> | |||
5) Repeat 3) and 4) to drop more tomatoes, chilis, basils and mozarella cheese layer by layer. Moreover, we could rotate assets to make it more real pizza by rotating function.<br/>'''Function''': ''tomatoes()'', ''chilis()'', ''basils()'', ''mozarella()'', ''random()'', ''rotate()''<br/><br/> | |||
6) Enjoy your Pizza Chilino :) | |||

[[File:pattern_rhombus.jpg|400px]] <br><br> | |||
One single cube consists of 3 rhombs which can be drawn simply by using the<br> | |||
”beginShape()-endShape()” method. Besides, the values of their coordinates<br> | |||
and colours depends on the angle of perspective from which we want to look<br> | |||
at the cube. After that we have to make a row by using the 'for loop ' and<br> | |||
another 'nested loop' for making the columns. As we can see in the image,<br> | |||
each column underneath isn't placed exactly in same order as their previous<br> | |||
ones are. There are shifted sideways by half the size of a single cube for<br> | |||
each time the nested 'for loop' is calculating a further one.<br> | |||
[[File:pattern_rhombus2.jpg|left|thumb|wrong!]] | |||
We have to consider that moving the columns in only one horizontal direction <br> | |||
will cause a bad looking stairway. To get rid of that, we have to find a way <br> | |||
to turn the values from every 2nd counting step the nested loop does, into <br> | |||
negative values instead of just adding them, so that each 2nd column is placed <br> | |||
back to its original starting position. This can be done for example by declaring <br> | |||
a new variable that is working as a multiplying operator and carries switching <br> | |||
values of 1 and -1.<br><br><br><br><br><br> | |||

Um dieses Muster zu beschreiben bräuchte man eine for-Schleife. Je nachdem wie oft sich das Muster wiederholen soll wird der Endwert festgelegt. Zum Beispiel auf 8. Diese Anzahl an Iterationen wird benötigt um das Muster einmal ohne Wiederholhung darzustellen. | |||
Beginnen würde man beim ersten großen gelborangen Rechteck von links. Danach zeichnet man die kleinen Quadrate mit den roten kleinen Rechtecken dazwischen von oben bis nach unten. Dann das Orange Rechteck und dann wieder die kleinen Quadrate mit den roten kleinen Rechtecken. Jetzt folgt wieder das erste gelborange Rechteck. Danach wieder die kleinen Quadrate mit den kleinen roten kleinen Rechtecken. Jetzt folgt ein großes Rechteck und zum Schluss wieder die Quadrate mit den kleinen roten Rechtecken. | |||

Most part of spider consists of symmetrical patterns. The definition of size (width, height, P3D) can let the patterns move around the y-axis and present as the mirror effects. Looking closely to the spider, it can be divided into 4 parts, antenna, head, body, and leg, which are mostly made up by circles and lines. | |||
# The antenna is not a regular pattern,use the shape() to draw on of this and then move it around the Y-axis for (PI). <br/>'''Function''': ''beginShape();endShape();rotateY ();'' | |||

# body can also be seen as collection of ellipse. Two big ellipse are surrounded by 6 small ellipses. <br/>'''Function''': ''ellipse ();fill();for(){};rotate();'' | |||
# The spider has 8 legs, 3 long and 5 short feet. Use for(){} to copy the lines and make it turns in the certain angle. | |||

The pattern consists of one basic shape – the shape of the leaves. One leave has an organic figure which could be transformed into a geometric form. This geometric shape exists of three equilateral triangles: the first one is the biggest with the hypotenuse at the bottom. The other two triangles are smaller than the first one. They are half sized and arranged in a diagonal way. Two-thirds of those triangles are inside the bigger triangle. Their top shows one to the left and one to the right side. | |||
The leaves have different sizes which are organized randomly. They are arranged along a line, one to the left and one to the right side by turn. Those lines grow in parallel and even sometimes overlapping. Through this the pattern has an appearance like an organic, random grid which is extendable in all directions. | |||
