Final task of the workshop with Nervous System was to design three 3d-printable cups using reaction diffusion.I used the following 3 techniques developed through the workshop to constrain the reaction to a cup-like shape. All using the Gray-Scott Reaction.

CUP #1 Ė Time ExtrusionIntroducing anisotropic diffusion of chemical u by having different diffusion rates in the x and y directions to create asymmetry.F and k parameter of reaction are changing through space.Controlling mesh generation by continuously restraining reaction-diffusion to happen within a set of law curves defined by mathematical formulas. Actually constantly controlling the concentration of the two chemicals to create void or solid.

CUP #2 Ė 3D Setting up an initial concentration of the two chemicals within a box to start the reaction-diffusion.Diffusion of chemical V is fixed. But the diffusion rate of chemical U changes through space so that it diffuses 2 times faster than V in the X and Y direction but diffuses with the same rate as V in the Z direction.

CUP #3 Ė Mesh DistortionDistorting a regular mesh of a cup by using information from a Reaction Diffusion simulation to modulate the mesh.Diffusion rate of chemical U is 4 times faster than chemical V3 cups are generated by using different parameters for F and k in the equation of the Gray-Scott Reaction

These three projects conclude the workshop with Nervous System. The final assignment was about making an industrial product (cup) using forementioned processes. First design is a cup, where the RD on a 3D mesh object is used for forming the outher shell of a cup. For the second and third design RD processes growing in 3D were used to make a different rounded shapes. These specific shapes were based on the specific RD parameters that were chosen because they give the rounded half closed forms – suitable for storing things. Second design is a combination of an aquarium and flower vase, and the third design is a spatial instalation that shows the creative potential of using these volatile processes.

The task was to explore the reaction-diffusion simulations and modify them to create the images. This images should explore how the patterns change when I vary parts of the process througth space and time.I used the 2-d Arrays to very the Diffusion rate and tryed out different reactions.

This assignment explores the Reaction/Diffusion processes, and one particular among them – Gray Scott Reaction/Diffusion. In this assignment, I used one reaction as an animated brush that bounces around the screen with changing speed, while the reactions in the background are changing their parameters.

facade presentation

Final exercise of the week was to design a new facade for the HPI building on campus.In the group we decided to create a second skin for the existing building.Mapping the functions inside the building and using Processing to inform the pattern generated by the different functions through a morphing pattern on the facade.The height of the opening was related to the functions requirement for a physical opening as a window or a doorThe width was related to requirement for a view out from the roomsWhereas the distance threshold was related to the functions requirement for sunlightAfter a range of iterations a pattern was exported as a pdf and opened in Rhino to prepare it for the final production of a 1:100 physical model on the replabs lasercutter.

domino facade

The task was to design the parametric facade for HPI building at ETH campus.The facade was to include both: the building’s surrounding and interior space functions.We decided to make the „domino facade“. We realised that there is „no welcome“ to the ETH campus, so firstly we create the separate panel befeore the main HPI building . The facade was build from separate, vertical, thin panels. We started from one game of „domino“ but after create the „domino effect“ we realized that it is boring and we complicated the rules by adding additional domino games, so in the same time few people could play together.The „domino effect“ can start and finish in the different levels. In the project we were interested in the information system which was transfere to the next elements and possibility which single elemet could have abut entire system. Each single element transfer information to other elements, so in this easy way each element know everything about others.

Since this particular assigment was beeing done individually, the idea was not to make a whole facade project program, but to conduct an experiment with a single facade plane. Few different approaches were tried out with random openings based mostly on room light requirements, but the final solution was based on a light map. Light map is an image of mapped light requirements for a room/part which the facade element encloses in a form of grayscale image with normalized mean value which is expected. Then, the openings were made as a horizontal cutouts in the facade plane representing light sections, where the height of an cut is correspodenting to the light-map value in a given section.

Can architecture be computed? The potential of computational architecture goes far beyond curved surfaces and free-form geometries. Rather, it is an entirely novel method of design. This method can not only generate previously inconceivable forms, but can also enable designs that incorporate complex sets of relationships with out resorting to reductionism.

In using these technologies, the architect no longer designs the geometry, but rather designs the process by which the geometry is generated. The architect forfeits direct control over the form’s appearance, while asserting control over the form’s desired attributes. It is through definition and an abstracted specification of these attributes that design decisions are performed. Once a solution space has been encoded, the architect assumes the role of a nurturer and moderator, recursively applying the processes until the most ideal configuration has evolved.

The role of the computer progresses from a drawing aid to an intelligent assistant. Information technologies thus bring design sketches to life: points, lines and planes gain intelligence and work together towards a common goal. Objects are no longer regarded in isolation, but are interlinked and connected to their environment. Depending on the nature of the code, the computer is able to independently vary, evaluate, and select designs. An optimization takes place that ideally is able to embrace the complexity brought about by juxtaposed objectives, rather than having to simplify these. Entire families and landscapes of objects can be generated: singularity turns to plurality. In the best case, the computer devises surprising typologies that go far beyond what one may have conceived of.

Benjamin Dillenburger writes programs instead of drawing. In presenting his most recent research and projects from the Chair for CAAD at the Swiss Federal Institute for Technology (ETH) in Zurich, he shows possible trajectories for the use of computational design in the field of architecture. The scale of the presented projects ranges from computationally generated ornament, to buildings, to an urban scale. Yet all projects have a common denominator: they are conceivable only through the use of information technologies – they are undrawable.

As an assignment to design a game from scratch in one day I were inspired by the classic arcade game named Breakout.Breakout was one of the first truly, endlessly, maddeningly addictive games ever invented. A variation of Pong, but instead of the ball bouncing between little rectangular paddles of you and your opponent, in Breakout you were fighting against a bunch of rectangular blocks. The ball bounced off your paddle on the bottom of the screen, smashed blocks, which were in rows at the top of the screen, and bounced back down to your awaiting paddle.

This task consist in making game. This game called points fighting.

games rules:

You have 2 points(„a“ and „b“). The second one (b) follows the first one (a). The space in which those points(„a+b“) move contains the dots in 2 different colours: red- means the movemant (of the point b) to the right side when he is close to red dots. black- means that point b is stacking when he touche black dots. If point b touch the black point he stick and game is over! If not he is follow the point „a“, which trys to run away!
