————————

For this project, I wanted to experiment with manipulating forms in three dimensional space. As someone who loves mathematical patterns, I explored ways that I could utilize the oscillation of a Sine wave.

Joseph Zhang — Project 12 — 3D Sine Wave

For my final project, I want to create a manipulatable 3D sine way form. This wave reacts to the mouse position as well as possible keys on the keyboard. I plan for the sine wave to be made of a individual particles, whether it be letters, circles, or cubes.

I’ve always wanted to do something including the third dimension and after seeing that p5.js can utilize webGL, I became really fascinated with possible ways I can do that. Changing variables include color, height of wave, and possibly orientation. Ideally, mouse position will control the location of where the max height of the wave will be. Keyboard functions may dictate the height of the wave, or if I can figure it out, the actual orientation.

My goal for this is to be able create 3D space using 2 dimensional elements. Obviously, 3D in P5 isn’t something that I’ve explored yet. However, it is something I’m eager to explore and learn about.

Hyperobjects – Erwin Hoogewood- 2019

Chihiro Sakoda – 2019

For my final project, I wanted to look into two computational artists Erwin Hoogerwood and Chihiro Sakoda. Above are two javascript projects that utilize various forms in geometry and nature to create beautifully animated forms. In both projects, there’s a sense of orchestrated randomness that’s really intriguing to observe. The one above by Hoogerwood is definitely much more systematic and geometric while the one below by Sakoda uses random participles to create something that seems more free flowing.

I would love to see how these artists might be able to make their respective art projects interactive. That would be really fascinating to interact with because it gives us as the user a new sense of agency. I think without this form of interactivity, these beautiful projects remain as cool animations with not as much depth as there could be.

    }
    return sb;
}

As winter approaches, I wanted to create a landscape that reflected the brisk temperature. In this code, there are two arrays, on that randomly generates snowballs and one that generates a new moon form every time it runs across the screen. Objects were created for both the moon and for the snowballs, where parameters such as color, size, and position were dynamically varied.

Below are sketches of my idea, I wanted to create a sense of time of day, sense of direction, and sense of environment. Much of this was done through the use of color which is made of entirely of cool tones and white.

Joseph Zhang – Looking Outwards – 11

For this Looking Outward, I really wanted to look at Amanda Ghassaei design work, specifically her 2017 Origami Simulator. A little about Amanda, she is a graduate of Pomona College and MIT’s media lab. Currently, she is working as a research engineer at Adobe’s Creative Intelligence Lab. With a background in physics and eventually design, she is applying her expertise in the fields of computational design, digital fabrication, and simulation methods

Origami Simulator is a WebGL app that mimics how a certain origami pattern creases and folds. What’s really interesting about this simulator is that contrary to the normal process of making one fold at a time, the simulator attempts to fold creases all at once.

Crease patterns are uploaded into the app as a SVG or FOLD format; from there, the app uses color and opacity to visualize the direction and fold angles of each crease.

The Origami Simulator app also connects to virtual reality and a user is able to interact with the digital forms through that as well.

Overall, I just really appreciate the way Amanda has brought both structure and delight to the seemingly ordinary concept of folding origami.

In this project, I used the metaphor of the ball as me as a young adult. There are boundaries that we’re given and often times we’re tempted to cross them. We’re often warned, but we’re not stopped. Ultimately, it’s up to us.

Sonic Arcade: Shaping Space with Design is a multi-component exhibition featuring interactive installations that experiment with the computations of Sound Design. The exhibition showcases several solo / collaborative works that, in one way or another, helps the audience feel more integrated into the spatial environment. The work utilizes electronic circuits, signals, radio waves, and resonant bodies to create these immersive experiences.

Though all these pieces are drastically different from each other, each utilize sound as a substance as the primary medium in each installation. In the exhibition above, Studio PSK uses body-activated MIDI sensors to detect when sounds should be triggered / altered. With these sensors installed throughout all the structures, the entire exhibition becomes a musical instrument itself, ultimately allowing viewers to both watch and participate in the art.

http://refikanadol.com/works/melting-memories/

For this week, I looked at Jenny Lee’s Looking Outward-07 article focused on Refik Anadol and his project Melting Memories. Refik is a computational media artist who blurs the lines between computation and installation-based digital art.

https://courses.ideate.cmu.edu/15-104/f2019/category/looking-outwards-07/

Like Jenni, I am also completely fascinated by Refik’s algorithmic methods and uses of brain data. It’s always really incredible to see the thought process behind certain projects and this was one of them. I was also in love with the way Refik decided to actually render the information in visual graphics. The forms are so elegant and natural, but so clearly computational.

Below are screenshots of data used in the project. Seeing the backend of Refik’s practices is really inspiring to analyze.

Joseph Zhang – Looking Outwards – 08

Website: https://nicolation.net/

This week, I wanted to look at Eyeo 2019 speaker Nicole Aptekar. Nicole Aptekar is a computational designer who utilizes three-dimensional rendering techniques and transfers them to physical mediums through lazor cutting techniques. For many of her works, Nicole develops custom software to generate these design. One of my favorite series is Metaflux, which is shown below. The compositions below consist of layers of paper stacked on top of each other to develop these beautiful forms that take advantage of light and shadows. As you can see, Nicole is really focused on geometric form and geared towards understanding how these forms and work in harmony with each other.

https://nicolation.net/category/metaflux

In her talk, Nicole talks a lot about how her work revolves around finding that middle ground where the physical and digital mediums meet. She tells her story through visually and verbally showcasing her work and how it relates to her as a designer and human. In her presentation, she also breaks the fourth wall and really talks to the audience as a friend. Her use of both digital and physical technologies to create novel art embodies her mission of pushing fabrication techniques and conventions.
