Algorithm for Computers 0

Result Algorithm
ascending triangle algorithm Filling an array with random points in an ascending interval and connecting those with triangles.

random_lines_asc.pde
Result Algorithm
ascending triangle algorithm Executing the algorithm mirrored with different color results in a picture which could be used for a cracked version of Windows ;)

Algorithm for Computers 1

Result Algorithm
nestedForLoops Nested for Loop with a certain offset per point & frame

funny_jittering5.pde

=Algorithm for Humans 1

Result Algorithm
first_algo Necessary Materials:

- 1 blank sheet of paper (any size) - 1 compass (or just a glas which you can use to draw a circle) - 1 pencil - 1 thick pen (favorite color)


Steps:

First part: Use a pencil and draw thin lines

Draw a circle in the middle of your paper with ~ 12 to 18 cm diameter.

Draw a vertical line through the middle of the Circle,

Draw a horizontal line through the arc to get 4 pieces.

Draw 2 more lines till you have 16 pieces with the same size (i.e. 8 lines)

Label the intersections of lines and the circle from 1 to 16.

Second Part: Use a pen of your favorite color

Let x = 0.

Draw a line from the middle point to point 1 + x.

Draw a line from point 1 + x to point 2+ x.

Draw a line from point 2 + x to the middle.

If x is smaller than 13, add 2 to x and repeat the last three steps.

If x is bigger than 13, draw a line from the mid point to a any corner of your sheet.



Unfortunately Manuel was a very strict HGP so when he got in next-to-last line he repeated the last three steps and stopped. Maybe I should be more precise next time ;)

Algorithm for Computers 2

Result Algorithm
lines & rectangle rotation algorithm The same random points are used to generate rectangles and lines, and are rotated afterwards. One rectangle differs in color.

Result Algorithm
lines & rectangle rotation algorithm Another outcome of the algorithm above..

Algorithm for Humans 2

Result Algorithm
coinflip algorithm Algorithm in picture. Manuel also used the "painting direction" as another variable.

Algorithm for Computers 3

Result Algorithm
Lines on circle points are animated with a noise in x & y direction using mouse as input. At a certain point, the lines of the last figure are connected to the mouse. sin_cosin_mouse.pde

Result Algorithm
cosinus & sinus algorithm plotted The "first step" of the algorithm above drawn by our HP Plotter High Resolution PDF

Algorithm for Humans 3

Result Algorithm
pedometer algorithm Algorithm in Picture. Not the most appealing algorithm, but I think it`s fun to see, what people are doing throughout the day. Maybe it`s necessary to improve the graphical part to make it more beautiful.

Algorithm for Computers 4

Result Algorithm
A modified version of our Balloons, using Spheres and the Toonshader to get ascending eyes which follow the mouse cursor - not the most precious code, ;) Also tryed to get the eyes looking at ones face with openCV, but this didn`t perform well.[ Problem here is, that the Wiki doesn`t allow to upload shader files.

Algorithm for Humans 4

Result Algorithm
Kreisel_des_Rechts.jpgKreisel_des_Rechts.jpgKreisel_des_Rechts.jpgKreisel_des_Rechts.jpg This paintig was excuted by my friend in the holiday break. Therefore it was possible to choose some more uncommon materials and tools.

(Given) Materials:

- 8 acrylic colors
- a spinning top
- blank sheet of paper
- 4 medical syringes
- one solid base for spinning
- one stopwatch (with 0.00 seconds precision) (+ one person who stops the time for you)
- any webbrowser

Der Kreisel des Rechts („Spinning Top Of Justice“)

• Take 4 of the 8 given acrylic colors. • Give them a ranking in your personal favor from 1 (least liked) to 4 (most liked) • Mix the colors with water and fill the syringes with them by multiplying the number you gave them multiplied by 0.2 ml (e.g.: most liked color => 0.8ml) • Execution: Read the following steps in advance:

◦ Repeat the following substeps for all 4 colors:
◦ Start spinning the circle and start the stopwatch
◦ While the circle is spinning, spray the color  on top of it
◦ When the circle stops spinning, stop the stopwatch and note the time 

• Multiply all measured times by 100 (to get rid off the decimals) • Open the website https://dejure.org/ and search for the results of the last step • Take the word that describes the topic off the paragraph in the best way • Write the number off the paragraph and the word in the middle off the „circles“ that you produced with your spinning top.


Algorithm for Computer 5

Result Algorithm
An picture based algorithm similar to the one we did in class. This time I used a counter to define average values of different gridsizes. image_avg.pde (Unfortunately I get an error message when I try to upload the code)
