Archive of Pendulum+Digital+Fabric.pdf

Originally, I wanted to put another screen for archiving along with showing fabrication process like a photo album. So that the concept of heritage can be actually seen and also gathering the image datas, it was interesting to think about patterns created by logical randomness can be an another tendency or flow of unspecified individuals. Lining up left over images made a certain feeling of seeing a pattern in complexity just like looking at the trajectory of double pendulum movement. It was nice to bring that idea and physically feel in reality.

Harmony of Ancient and Modern technology & perspective of Deconstruction

During the process of my project, I felt that pendulum is a simple physics tool not exactly from ancient but has primitive structure and with the same way of using, it results to totally different way of generating complexed digital images. I feel my project literally shows visualization of human heritage where I feel wonder about it. Combining notions from different fields like fashion, art, physics etc, I want my art piece to be an example of realizationing the imaginated ideas for the upcoming future(4th industrial revolution) which has a key concept of super fusion. Biology, manufacturing, motor technology etc.. everything is becoming combined more and more easily and if specializing into one subject was beneficial until now, taking concepts around the world and creating a new notion will be beneficial and will be possible. I think it is a good opportunity to make the dream come true at this point of time. To do this, one of the methodology I want to suggest is having a or rather many perspective of deconstruction. Dissolving the structure, theme, notions and by looking at seperately, it will make a bit more clear what materials that I can use to combine and inspire the creativity.

Concept of Automatic Digital Fabric Generator-

Thinking about how to visualize the converted physical datas, rather than giving generative drawing images using only computing notions, I came up with an idea of applying NFT notion and combine it with fashion fabric. By framing the complexed patterns of visual outcome as a rectangular shape, I could apply the notion of digital fabric sample just more than digital generated images and by generating a private code with the digital fabric, I can strengthen the idea of identifying the users and personalize the visual outcomes. I am not applying the NFT notion to make something profitable, but actually it is to use the trend make the art piece more familiar and enjoyable to the public. I feel this kind of attempt is good way of thinking as an artist considering the perspective of the audiences which makes my narrative more understandable.

Creating digital data of Pendulum movement-Arduino sensors or 3 faced webcams?

Thinking of methodology of how to convert pendulum movement which is physical data to digital data that I can use in computer for visualising, two options were using Arduino with sensors(ultrasonic, magnetic hall, infrared etc..) and using webcams by setting them at top, right, left to create something like x,y,z plane and define the movement by position. 

Using sensors may let able to collect more practical and precise datas of the actual physical datas. But research of the sensors should be done and have to learn Arduino physical computing.

Using webcams may not be precise in datas and not sure how much variation would eventually come out but I can maybe add machine learning system at certain point like defining whether the pendulum movement is activated or not. Other than that, it may cost more and it may limit the esthetic with three cameras on the sides.

Idea of pendulum as interactive element in interactive art-

Double pendulum is one typical example of showing chaos theory. By seeing the movement and then the trajectory of it, the randomness seems to be totally unpredictable but creates certain patterns when visualizing the trajectory. The key element that defines the difference is initial condition of the pendulum. My idea is that every audience will give different condition to the pendulum when making the movement of the pendulum and just like butterfly effect, the system maximises the little difference between the initial conditions. In this term, single-rod pendulum can have the same feature. I found it very interesting that if I could create certain process of visualizing by using the certain data from the pendulum movement, I could identify each movement and give severalty to them which can be similar to security password system maybe. What beneficial more is that giving an initial condition to pendulum(direction&force) is just simple as unlocking smart phone screen. Just pull to the position and let it go. Identifying the audience without any QR code or personal information and giving individual interaction with the art piece is truly beneficial as an interactive method. The thing is to how to collect the data of pendulum movement, and how it will interact or visualize the datas.

Exhibition participation role in group

Among the groups in degree show, my major role was in technical & curating team. Technical & Curating team was the first people who was to contact between hatchlab technicians(Rob,Luke) and the students. I myself have gathered tech request & risk assessments forms from all years and made spread sheet to share with other tech team members(Theo, Isaac). Our team has discussed how to allocate each students to appropriate rooms throughout several meetings and throughout the process, we were all kind of acknowledged about what projects each students are doing and answered the questions from other teams about it. The major discussion was about which room to use and which room to not use as the building was too big to use all the rooms and create a theme for each rooms considering the perspective of audiences while making sure everyone is satisfied with their allocated rooms. We also made stairway plans for the audience and the staffs but could not use as Oxo Tower had their own plan. I believe we shared our thoughts freely and worked well as a team during the exhibition. Other than that, I tried to participate other parts suggesting themes for the show, color pallet with design team, and participated every clean ups and helping the vans.

Using Mac Automator to automatically print from printer-

By setting up a particular finder folder to pass the image file to the printer whenever an image file is added to the folder, openframeworks code automatically saves the image and could set up automatic printing system. One critical issue was by using this system, the printer waiting list window pops over the openframeworks debug window that the openframeworks window has to be clicked again with mouse interaction. This really annoyed me as I wanted to minimize the interaction just to the pendulum movement with the users including the disruption of installation layout with a mouse. I have spent quite a lot of time solving this problem trying openframeworks game mode, openframeworks window systems, mac applications to set certain window always at front. The solution I did was in the automator, create a workflow of running openframeworks debug app after the printing action which is equal to clicking debug window.

Final testing for variation of patterns

By adding noise values to z values of first and second meshes as well, I made three meshes overlap according to time flow and the wave of z values makes more variation to the patterns. Initial conditions are based on the private code and visual outcome differs by the private code numbers. I also considered using more number of meshes but as the code will run for 8 hours during the exhibition, I stayed at three to not slow down the visual process.

Testing the fonts-

I tested out around 50 fonts and during the process I found out that changing numbers for private code changes the length of the text especially when the numbers are updated to random numbers to show processing which was not visually good looking. To solve this, I picked out mono spaced fonts which is fonts with same width. They still have slightly different sizes which makes the length change but much more better than other fonts. Esthetically I considered Roman style fonts for ancient esthetic and bitmap style fonts for digital but I wanted to balance between them so I chose thin and modern style font named Zector.ttf at the end which is the top picture.

Default setup decision for exhibition screen.

With = 300

Height = 200

Translated texts to 90 degrees using rotation. This layout is consideration of using vertical displayed TV screen hanged on the wall at the exhibition. Changed the background to white for the idea of physical prints out which white A4 paper will be used. Default color set to blue as I personally feel modern esthetic and comfortable with other white colored installations.

Orthographic camera experiment

To combine the meshes into a frame like rectangle fashion fabric, I found a function called orthographic camera which ignores three dimensional perspective. This function is perfect to fabricate the meshes into 2D plane. Though, orthographic camera is not affected by the camera position, so I have to increase the absolute width and height numbers, or scale the size which I need to figure out the best optimization to visually impressive while not slowing down the computer.

Procedure screenshot of lerping position and colors of perlin noise mesh.

 Rather than turning meshes into noise meshes instantly, I want to show the process of fabricating to the audience to more efficiently deliver the idea of generating my own digital fabric pattern. Created old position, lerp position and lerp color to use it as medium value between old and new mesh.

experimenting 3D mesh with perlin noise, colors, point size, wireframes. Time increment is needed to use perlin noise application. Applying noise values to x or either y values kind of folds the mesh into vertical and horizontal shape which is interesting to make unique patterns when overlapped.

3D Mesh vs Flowfield

3D Mesh and Flowfield is representive generative drawing technique using perlin noise. In case of my project, 3D mesh can give more three dimensional images and strengthen the idea of fabricating 3D forms to 2D fabric sample. On the other hand, flowfield can be more beneficial in realization of detailed texture.
