## Yingying Yan – Final Project

In architecture, we often have to use brushes in Photoshop. A good brush often makes a drawing very successful. Thus for this project, I decided to render a brush with cubes rotating at different angles with a change in gradient depending on the number of cubes that are drawn. Since WebGL does not support text, I could not explain the direction on the canvas. But ways the users can interact with the brush are: “h” = erase the canvas, “j” = turn off the randomness in size, after pressing j, the user can press “l” to make the cubes bigger, or “k” to make the cubes smaller. The user can also press a to increase the speed of rotation.

## Yingying Yan- Project-12-Proposal

For the final project, I am interested in data visualization. More specifically, I want to represent the data of Pittsburgh’s rainfall record using what I learned from 104. The goal of this project is to allow people to “see” how much rainwater Pittsburgh gets for the past year. And what we can possibly do with the rainwater if we collected fifty percent or thirty-five percent of it. The project should also be visually attractive and easy to understand. So the audience will be interested and comprehending the message that the project tries to relate.

I am not sure how this project will look like yet.

## Yingying Yan-Looking Outwards-12

The two projects I find interesting are both from data visualization practitioners. Phantom Terrains by Stefanie Posavec is an audio interface which communicates the silent wireless signals that are in London, where they collected the data from. The goal was to convert the characteristics of the invisible wireless data into sound. People will be able to hear the changes in the landscape of sound around them. I am less interested in what the experience the soundtrack creates. But the visualization that the project created is very interesting. It conveys the information while also visually attracting.

The second project that I am interested in is Unnumbered Spark by Aaron Koblin. This is a sculpture or building size installation that allows the audience to control the projection on the soft fabric. This project is more like a motivation for me. Allow me to see what data visualization can possibly become.

A long distance relationship is a project done Cecdet Erek, who is one of the founding members of an experimental outfit called Necropsy. The project focuses on the relationship between two points, space or time. The continuation of his ongoing project Rulers and Rhythms lies in between two rhythms centered pieces conceived for MUAC: Measures Taken and Close FarClose. This project is not only music itself but also combines computational musind architecture. I think it is very cool to vary the media and add elements to other projects. I thinking of

I wanted to render some snow scene because I love the snow. Unfortunately, I can barely finish the project. But I have a snowman! I mean lots of snowmen. I think this project is hard and really makes me think about “object”. I am still in the process of understanding the code. I think for my final project if I would do something similar, it will be much better than this.

Different from traditional architecture, architect Jenny Sabin’s Sabin Design Lab in Ithaca, New York investigates the interaction between architecture and science. They apply theories from biology and mathematics to designs, fabrication, spatial inventions and materials. The firm is a combination of engineers, architects, designers, artists, and even scientists. The scales of their work varies, from installation to a building facade. I find the form of their projects very appealing because it is dynamic and organic. It seems random but also has order and system to it.

The newest project Lumen creates a space I really want to experience. It is very interesting because of the fabrication materials, the shapes of each element and how the structure come together.

I regret using my little sister’s picture. She is so cute but I am not good enough to render her picture to something better. But that is ok because she will never see this. Overall I think this project is interesting. It is like making a filter for photoshop. I started the project by trying to do something fancy, but I failed. I will try to fix that after I turn this in.

## Yingying Yan – Looking Outwards 09

This week I looked over Romi Jin’s looking outwards 5. She is my mentor from architecture, so I thought I could learn from her. Her looking outwards was about occluder simplification. The reason why she chose this is probably that the occluder simplification used bunny as an example, and she loves bunny.

Shown by the picture above, the bunny changed from a normal bunny to a distorted one. This is because the algorithm takes in very few inputs and simplifies the geometry in an abstract way. As Romi mentioned, this can be very useful when applying to larger and more complex shapes. This algorithm produced a unique and interesting graphic compare to the original. Yet, I think it needs to be developed more because it could be more visually appealing.

Sha Hwang is an information designer who is working to improve the government at Nava. He founded Meshu, Motivity and worked for Trulia. He started by studying architecture, then animation, modeling and finally data visualization. His works are amazing, but his personality is what made him more successful. In the video, he said: “ I do not have much, but I have enough to give someone space, time to breath.” He knows what is right and does his best to support those rights. He mentioned his mother and her influence on him. He talked about lighting and how it searches for the ground similar to how someone can live one’s life and search for the “one thing” to do. He is inspiring, so as his artwork.

I am doing a mapping project in the studio now. Sha’s mapping methods allow me to think more out of the box. His mapping methods are simple, visually attractive, and more importantly, conveying the information effectively. There are 2D graphics, 3D representations, animations and more. My favorite project from his website is the Photo Reel, which is a collage. He combined 2D collage with computation interaction. I think that is innovative.
