1112 - 3d obj test

I recreated an object, I used the last semester, using metaballs in vvvv. This process is to check my writer patch and make the object more systematic.

/ 기존에 만들었던 3d 형태를 좀 더 조직적으로 만들고 싶어서 vvvv의 metaballs 노드를 사용하여 형태를 재구성해보았다. /

env obj + metaballs - 1112_env_metaballs_001 - 20131112

load the converted obj file into maya - 20131112

-----------------------------------------------------------------------------------------------------------

I reduced its vertices, and compared it with the first object. The new one looks much more systematic then the first one, but still there is something lacking. It can be used sometime.

/ 형태를 단순화시키는 과정을 거쳐 기존의 형태와 비교해보았다. 나중에 좀 더 짜임새있는 형태가 필요할 때 사용할 수 있을 것 같다. /

1112 - extract x file

The other day I couldn't extract 3d files from vvvv (link), so I tried again using a different way.

The way I used is as follows.

1. extract x files from vvvv
2. convert x files into obj files using another program
3. load them in maya

I think this way can be made an object which can be printed by a 3D printer.

/ 이전에 vvvv에서 3d file을 추출할 때에(link) 제대로 해보지 않고 포기한 것 같아서 이번에 다시 시도해보았다.

내가 이번에 사용한 방법은 다음과 같다.

1. vvvv에서 x file을 추출한다.
2. x file을 타 프로그램을 통해 obj 파일로 변환한다.
3. maya에서 불러들인다.

이 과정을 통해 3d print가 가능한 파일을 만들 수 있을 것이라고 생각한다. /

-----------------------------------------------------------------------------------------------------------
1 / extract x file
-----------------------------------------------------------------------------------------------------------

I composed my own writer patch to extract x files.

/ x file을 추출해내기 위해, 다음과 같이 x file writer 패치를 구성하였다. /

xfileWriter.v4p - 20131112

This patch is working well to extract x files from most of geometry meshes, but I couldn't extract any data from metaballs.

/ 하지만 몇몇 geometry mesh, 특히 metaballs 노드에서는 3D 형태에 대한 어떠한 정보도 추출되지 않았다. /


x file data from metaballs / sphere harmonic / sphere - 1112_xfileTest_001 - 20131112

I assumed some possible causes of this problem.

1. wrong x file writer patch
2. quite complex form
3. 3D object seems like real, but fake
4. occurred some errors in x file data

In case of number 1, it's not the cause because most of x meshes could be extracted by the x file writer patch except metaballs. And in case of number 2, sphere harmonic has a more complex form than metaballs. Also I thought metaballs are real 3D objects. Therefore I focused on the 4th possible cause.

/ metaballs 노드에서 파일이 제대로 추출되지 않는 원인을 다음 중 하나라고 가정해보았다.

1. x file writer 패치를 잘 못 구성해서
2. 형태가 너무 복잡해서
3. 3D처럼 보이지만 실제 3D가 아니기때문에
4. x file을 구성하는 정보에 오류가 생겼기때문에

metaballs를 제외한 대부분의 mesh에서는 x file이 정상적으로 추출됐기때문에 1번은 아닐 것 같고, 더 복잡한 형태의 sphere harmonic의 경우를 생각했을 때 2번도 아니라고 생각했다. 3번의 경우는 거의 불가능하다고 생각했기때문에 4번의 경우에 초점을 맞추고 진행해보았다. /

-----------------------------------------------------------------------------------------------------------

I modified the patch using mesh and vertexBuffer nodes. These nodes were used to split 3D data and organize them as x files.

/ mesh와 vertexBuffer 노드를 사용하여 3D 형태를 다시 구성한 뒤, x file로 추출할 수 있도록 패치를 수정하였다. /


x file data from metaballs - 1112_xfileTest_002 - 20131112

As a result, I could extract proper x files from metaballs.

/ 그 결과, 정상적으로 x file을 추출해낼 수 있었다. /

-----------------------------------------------------------------------------------------------------------
2 / convert x file
-----------------------------------------------------------------------------------------------------------

Next, I used 3D exploration program to convert x files into obj files.

/ x file을 obj 파일로 변환하기 위해 3D exploration이라는 프로그램을 사용했다. /

-----------------------------------------------------------------------------------------------------------
3 / load into Maya
-----------------------------------------------------------------------------------------------------------

And finally, obj files of metaballs could be loaded in Maya. There are a few missing faces but I think it has quite good quality.

/ maya에서 변환된 obj 파일을 불러들였다. 약간 깨진 부분도 있지만 대체적으로 괜찮은 것 같다. /

0916 - vvvv test

I did some tests for making realtime tracking points.

First, I made some points and connect them with lines. I supposed they are tracking points.

screen capture in vvvv - 20130911

And modified a line can control its thickness according to a distance.


screen captures in vvvv - 20130912

I will connect it with other electric signals and see how it works.


0905 - concept for further work

note

The main concept is the relationship between the visible and the invisible.
Also this can demonstrate similarities between human and computer.

논문 전체를 관통하는 핵심 주제는 눈에 보이는 것과 보이지 않는 것 사이에 어떠한 관계가 존재하는가에 대한 것으로, 기술이 발전하면서 인간과 컴퓨터 간의 차이가 점차 줄어들고 있음을 작품을 통해서 보여주고자 한다.

-
I expect the result as follows.
따라서 다음과 같은 결과를 기대하고 있다.

1 - get motions and electric signals data from kinect, webcam, mouse, and etc electronics.
--- 키넥트, 웹캠, 마우스, 기타 전자기기에서 움직임과 전기신호 데이터를 추출한다.

2 - make a realtime graphic which can show the relationship between them.
--- 이 데이터를 서로 연결하여 이들 간의 관계를 보여줄 수 있는 실시간 그래픽을 제작한다.

3 - we can see a kinetic network between human and computer(electronics), but can't guess if each data is from human or computer. (like the turing test)
--- 이 실시간 그래픽 작품을 보는 관람객들은 본인의 움직임에 영향을 주는 다른 움직임을 확인할 수 있지만, 이 움직임의 원천이 인간인지 컴퓨터인지 쉽게 판단할 수 없다. (이는 튜링 테스트의 과정과 비슷하다)

-----------------------------------------------------------------------------------------------------------

I wanted to follow these steps, but I'd better work them later. (perhaps someday)

0526 - plan for realtime object tracking

I'm planning to develop the previous work(link) into realtime. Maybe it can be possible to make realtime object tracking system(link_research) using kinect depth data, I will try.

이전 작업(link)을 리얼타임으로 만들어 보려고 한다. 키넥트의 depth 데이터를 이용해서 객체 트래킹(link_research)이 가능하다고 하니, 한 번 시도해봐야겠다.


0505 - data visualization ; social graph

This post is about the social graph (link_research), and it is connected to last posting ; small-world network (link)network ; how to connect (link)

This is a thought after reading <Beautiful Visualization> by Julie Steele and Noah Iliinsky.

Most importantly, beautiful visualizations reflect the qualities of the data that they represent, explicitly revealing properties and relationships inherent and implicit in the source data.(1)

While I was reading this book, I kept thinking if my thesis works are efficient data visualizations. It is common that a network visualization is used for showing relationship between any 2 object, but is this the best way?

줄리 스틸과 노아 일린스키의 <아름다운 시각화>를 읽으며 떠오른 생각.

효과적인(그리고 아름다운) 정보 시각화를 위해서는 해당 정보에 적합한 표현 방식을 택해야 한다. 임의의 정보 시각화를 통해 사람들이 새로운 지식과 이해, 그리고 즐거움을 느낄 수 있다면 그것은 잘 구성된 정보 시각화라고 할 수 있다.(1)

책을 읽으면서 내가 지금까지 한 작업은 효과적인 정보 시각화인지에 대해서 생각했다. 일반적으로 서로 다른 두 대상의 관계를 나타낼 때 네트워크 형태의 시각화를 사용하지만, 그것이 과연 가장 좋은 방법이라고 할 수 있을까?

0412 - human motion and programs

There are some programs I used for my project. I always move a mouse point for doing my works, and it is a human motion.

screen capture in photoshop

screen capture in illustrator

screen capture in indesign


screen capture in maya


screen capture in syntheyes


screen capture in after effects

-
These programs have different interfaces and color. And I think the working flow from them is very similar to the process of sound generation.

wave >> air >> sound
thinking >> programs >> graphic

like that.
So, it can make a connection between human motion and sound.


0409 - human and rules ; why?

I made this video and thought most of their movements were very consistent. But a few people moved different, and it made their tracks more interesting.

kinetic city architecture with human motion

screen captures in Syntheyes / After Effects

It reminded me of my design works about graphic, editorial, etc. I usually follow the design rules strictly, but I've never thought about why I must observe them.

The rules made me passive. They made my works boring. I think I'd better break them from now on.

If I break the important rules, the result will be like those.
_1/ disorder and terrible
_2/ unexpectedly good and unique

I expect this will make my thesis more interesting.


0316 - experiment ; game rules + QR code

I thought the rules of Baduk (or chessChinese checkers, etc) can give variety to fixed motions, and change the sound. But this was NOT a useful experiment for my thesis.

Can I use this idea for another work?

-
This experiment shows how game rules can change the sound.
I chose 2 songs randomly, and arranged go stones. Also some stones were removed according to the rules.

1st _ The Four Seasons ; Autumn 
2nd _ Moon River (white) vs The Four Seasons ; Autumn (black) 

-
Also this process reminded me of QR code. So I made some pixel images using these records of Baduk.

QR codes for my blogs 




Baduk codes for sounds

I think I need to research about gesture and sound.


0312 - analysis

Still I don't know how I can develop this subject, so I organized my thoughts about sound and gesture.

-
1/ the relation between sound pitch, human body, and math ; about length

sound pitch _organ / violin 

This is also related to Pythagorean tuning.



unit of length with human body + Maya numerals 


2/ visual or structural similarity with musical instrument + sheet

organ / organ sheet _ Twinkle Twinkle Little Star 
bread board / go equipment 
nonogram

3/ the relation between kinect and theremin


0218 - outline

/ Last updated 2013-12-22 /

The research about fingering in music and sound visualizer

In music, there are many types of fingerings according to musical instruments. For example, fingering of keyboard instruments have a wide range of activity, but it can be played through x-axis. On the other hand, violin and theremin can be played through x-y axis, and x-y-z axis each. If you play the instruments for a while, your movement can be made a specific curve like a lissajous curve. Also some organic forms and sound visualizer can be developed with it. (2013-2-18)


Gesture Controls Sound. Sound Controls Media.
How Human Motion and Sound can Control Complexity in real time graphics.

Human body has many organs and systems which can be controlled by an electric signal of brain. Also whenever people read music and a book, the first thing they recognize is sound (not visual information). But if they don’t know about their specific system and structure, they can’t understand the meanings. Therefore I’m going to research about the relationship between human motion and sound, and make the output. (2013-3-23)


Between the Visible and the Invisible.
How Human Motion and Electric Signals can Control Complexity in Realtime Graphics.

Human body has many organs and systems which can be controlled by an electric signal of the nervous system. This is very similar to the structure of computer which is controlled by many electric signals. Also we can see their motions but can't see their signals. We can just suppose their existences.
Therefore this research is about the relationship between the visible and the invisible, besides similarities between human and computer. (2013-9-26)


Between the Visible and the Invisible.
How Human Motions and Electric Signals can Control Complexity in Real Time Graphics

Human body has many organs and systems which can be controlled by electric signals such like a brain wave or a neuron signal. This is very similar to the structure of computer which is controlled by many electric signals. We can see their motions but can’t see their signals. We can just suppose their existences.

If some invisible components around us, for example electromagnetic waves from electronics can be seen visually and they are controlled by other motions in real time, we can feel something between the real space and the surreal space.

Moreover, people usually desire something new. It won’t be interesting to share the experience only between human in the near future, and this work will give many inspirations for connecting human and non-human.

For this reason, the whole process suggests a new way how to show the something between the visible and the invisible. I developed my works based on various styles of motion, connection, paradox, and dimension. Especially, a recontextualisation and an anaglyph effect that contain these key concepts were helpful to develop many experiments.

In other words, this work is about how to show the relationship between the visible and the invisible, furthermore similarities between human and computer through some experiments about how human motions and electric signals can control complexity in real time graphics. (2013-12-22)


0203 - intro

This blog is for my thesis project based on motion graphics and interaction under my supervisor, Prof. David Hall.
I will research > experiment > develop > draw a conclusion.

-
There are some keywords, which I have to select and develop afterwards.

/1

Additive and Subtractive : Moiré Pattern
A moiré pattern, created by two(or more) grids, can change its form and color depending on their movements. This means we can make various patterns which have different penetration ratios of light.


/2
Depth Perception and Distortion : Pseudoscope
.


/3

Shape and Motion : Hypercube / Tesseract
Tesseract can be unfolded into 8 cubes into 3D space, just as the cube can be unfolded into 6 squares into 2D space. This structure can show both sides of cubes, and connect dimensions in various ways.


/4

Sound and Form : Lissajous FigureHarmonographSpirograph
Sound and Form : PendulumFoucault Pendulum
Lissajous Figure is a flat image but it has 3 axes. By varying the frequency and phase of the pendulums relative to one another, different patterns are created. I think this is a visual identity of each sound.


/5

Persistence of Vision : Persistence of VisionThaumatropeZoetrope
An analog projector can work with one light and a vertical motion. On the same principle, it is possible to install many lights and make a combined image(or animation).


/6
Etc : digital and analog / additive and subtractive / plane and solid / horizontal and vertical / visible and invisible
