스트로브 여러개 활용

그림자를 활용한 Zoetrope에 두개의 스트로브의 빛으로 비췄을때 어떤 상이 나오는지 실험을 진행하였다. 실험 결과 다양한 패턴들이 나왔으며 입체적으로도 보는 현상이 나왔다. 결과는 다음과 같다.

Use multiple strobes

We experimented with what happened when Zoetrope used the shadow to illuminate the light of two strobes. As a result of the experiment, various patterns came out and the phenomenon of seeing in three dimensions came out. The result is as follows.

LED 시계 제작

시계의 역활인 정보 전달이 부족하여 LED를 활용하여 시계를 제작하였다. 시계는 와이파이 보드를 활용하여 시간정보를 불러와서 시간을 표현하였다. 시, 분, 초를 원하는 색상으로 표현 할 수 있다는 장점이 있다.

실험 도중 예전의 시계인 해시계의 모형이 나타나는 점을 발견하여 그림자를 활용한 시간 표현은 어떨지 고민하고 있다.

LED Watch Making

Due to the lack of information transmission, the watch was manufactured using LED. The watch uses the Wi-Fi board to bring up time information and express the time. It has the advantage of expressing hours, minutes and seconds in the desired color.

During the experiment, I discovered the model of the sundial, the old clock, and wondered what about time expression using the shadow.

Zoetrope 패턴 디자인(파티클 활용)

Zoetrope에 넣을 패턴 디자인을 진행하였다. 패턴에는 파티클을 활용하였으며 파티클의 개수, 밝기, 파티클 종류 등을 다양하게 변화를 시켜 어떠한 모형이 나오는지 실험을 진행하였다. 실험결과는 다음과 같다.

Zoetrope pattern design (using particles)

I did a pattern design for Zoetrope. Particles were used for patterns, and experiments were conducted on what kind of models appeared by varying the number of particles, brightness, and particle types. The experimental results are as follows.

그림자를 활용한 숫자변화

빛과 그림자를 활용한 Zoetrope의 시간변화를 실험해보았다. 실험에서는 일정한 거리로 멀어지니 숫자가 흐리게 나오는 결과가 나왔다. 오늘 빛의 세기를 더 강하기 하기 위해 20W Strobe를 구매하였다. 현재는 10W Strobe를 활용중이다. 그러나 예전의 실험에 나왔던 빛의 유지정도에 따른 모션블러 효과가 일어날 수도 있는 오류가 나타날 수 있다. 

또한 그림자를 활용한 패턴에서 외형에 일정한 패턴을 주어 그림자를 보았을때는 원형이 아닌 실험적인 모형으로 제작해 보았다. 이후에 다양한 패턴들을 넣어 다양한 그림자 실험을 진행 할 예정이다.

Numerical change using shadow

I experimented with Zoetrope's time change using light and shadow. The experiment resulted in numbers had made a blur effect by moving away from a certain distance. Today I bought a 20W Strobe to make the light more intense. I was currently using 10W Strobe. However, an error may occur that may cause a motion blur effect depending on the degree of light retention in the previous experiment.

In addition, experimented change of the circle shadow, this pattern was used as an experimental model. Various designs will be put in to experiment with multiple shadows.

3D 디자인을 위한 Zoetrope 디자인

3D 모델 Zoetrope을 제작하기 위해 역동적인 변화가 일어나는 모델을 제작하고자 하였다. 그러기 위해 3D Max에서 가지를 제작하는 스크립트를 찾아 이를 활용하였으나 가지가 Cone을 제작하는 형식으로 제작되어 3D printing 시 오류가 날 것 같고 원하는 모형으로 나오지 않아 코드를 변화하거나 다른 방식을 활용하여 Zoetrope을 제작할 예정이나 Scipt를 활용한 역동적인 디자인을 알게 되어 이를 활용한 모델링을 제작하기 위해 연구가 필요할 듯하다.

3D Model Zoetrope Design

To create the 3D model Zoetrope, we wanted to create a model with dynamic changes. In order to do this, we found a script to make branches in 3D Max and utilized them, but the branches were produced in the form of making Cone. Knowing the dynamic design using the schedule or the Script, it is likely that research will be required to produce a model using the design.

숫자를 활용한 Zoetrope 디자인

시간을 나타내기 위해 숫자를 활용한 Zoetrope 디자인을 제작하였다. 1-60까지 60초동안 변화하는 것을 목표로 하였고 그를 위해 다양한 시행착오들을 겪었다.
또한 Zoetrope의 비어있는 자리를 채우기 위해 30도식 돌리다가 15도를 한번 돌려 비어있는 공간을 채운 Zoetrope의 형태 또한 확인하였다.

또한 작은 Zoetrope에 넣을 디자인으로 상자를 통한 변화와 파티클을 통한 디자인을 시도해 보았다.

Zoetrope design using numbers

Zoetrope designs were created using numbers to represent time. It was aimed to change for 60 seconds from 1-60. Various trials and errors happened while I was looking for the right pattern.

Also, I tried to change the design through the box and the design through the particles as a design for the small Zoetrope.
