Chapter One. Inspiration | Sketches
I started sketching after inspired by my personal adventure (looking at different places like buildings, golf place, streets, etc). I just played around with shapes but the biggest challenge was that I need to make it not too complicated so that later on, for the interactive part, I would make a connection. I think I need to sketch more, even if it is a failed object. I should keep on trying to play with the shapes. I wanted to sketch first because I never tried Maya 3D before, so just for a warm up.
Inspiration | Sketches
When I first thought about this project, I did not know where to start. So, I started just walk around places. I went to Daegu this weekend to help out with the golf place. Through gardening, I found rocks that had different sizes, shapes, and colours. This was interesting to
see because in each rocks, it was made naturally. I wanted to use this idea to express the nature of the rock (everything about the rock has it own charm and it would be interesting to observe this). Also, important part about this process was to play with Maya.

I was frustrated with not knowing where to start. I had to rethink about playing with shapes with interaction. I wanted to play with triangles because I love its sharpness with faces that could be connected with other shapes. The idea that I had in mind with my sketches was playing with different heights of the same size of the triangles. Also, placing each other equally with a slightly different x-axis or y-axis. The sketches are simple to begin with but I know it would process through to a better result.
Maya 3D test.
I tried to redraw my sketch on Maya 3D but I was just having a hard time aligning the shapes and just controlling everything. So, I wanted to express the 3D of my shape using illustrator. They have a effect that turns into 3D. It was much better to just see how the 3D shape of my sketch looked. And I
edit some parts of my sketch because I didn’t draw it the right way. To check simple shapes, it is so much better to play with illustrator. But I knew I had to re draw it in Maya 3D. Through this process, I could understand the 3D objects and how it is presented.
Inspiration | Sketches
This object design is from my simple triangle sketch. It is still simple. I feel like I needed more inspiration to design various objects. But from this test, I like the different levels of each triangles and that this could be interesting to test out for motion with the objects (vertically or horizontally). My future thought to this project is that I could design something like rear wheel’s motion.
Inspiration | Sketches
This is from the garden in front of my house that I found. This inspired me with the repetition of the petals. Each having little bits of different shapes but is align perfectly. I wanted to make my object similar to the idea of a flower. Also, each petals rotating
to make a flower shaped object. I would like to play with the animation and interaction. I know my object is going to be simple but I need to think about the angles of each petals that is going to move and the speed of the rotation.
Inspiration | Sketches
This was the object that rotates with the repetition. I wanted to express the idea of the flower petals. How it slowly turns into a flower and also, giving a different level of the height to give depth. I just tested out the placement and how it should move in the exact time. I needed to think about how I’m going to move each petals with one motor. My challenge was the placing each petals as close as possible.

Final Concept
Final concept is growth of bacteria. I actually tested out growing on rice cake. I couldn’t take pictures of the progress but this was the final step of growing.
Chapter Two. Process of composition: Mapping Test
I have decided to use my first flower shaped model to do projection mapping. So, I printed out 6 of the object by using Pepakura. This program made it so much easier to cut my object because they al-
ready gave the guidelines. I glued everything and stacked all my object as the result of how it will look like after movement. The problem that I had from this was the weight of the objects on top.
I started to map my model using photoshop. I practice lining it perfectly but was hard. I played around with the angles to see which view was the best to project. The challenge to this was making the lines as close as the
edges or else, the lines that is projecting would stretch. I needed to be careful when I tried to map my object. This was the most important step in projection mapping.
Process of composition: Arduino test
Process of connect Arduino to my motor shield, we’re done with projection mapping and installing Arduino to our machine, need to finish connecting Arduino to Motor Shield and test.
Process of composition: Stepper test
To use the shield on an Arduino, I installed the Adafruit Motorshield v2 library. Then, connected my Arduino and tested stepper test (file > examples > adafruit_motorshield > stepper test). At first, when I connected, my motor would not respond. For about an hour, I was figuring out what the problem was but could not find it. After asking other people, I found out there was a “on & off� switch (insert the VIN Jumper shown as the tall black handle right next to the green Power LED).
Process of composition: Continue Stepper test
Arranging/placing our motor, shield, projector, and etc.
The angles that I set matches with the mapping.
Process of composition: Continue Stepper test
Hard Paper Laser Cut.
Using my new model, I wanted to test out the speed and set the rotation.
Process of composition: Continue Stepper test
Outline my model. I found out that was the printing problem or Pepak easier to outline from illustrator. Th
t my model was reversed. Maybe it kura. I thought laser cut model was he edges are nicely presented.
Process of composition: Continue Stepper test
Set up the project in the same eye level with my object model. Through the same process, I found out what I was struggling with. Projecting and getting the outline is no problem but importing the outline in Maya and finding the right angle is impossible. I kept on stopping at that process. This was my final coding to use for this process. Using the Microstep steps with the speed of 20, then set to stop after half rotation and rotate back after 1 second delay.
Process of composition: Continue Stepper test
First test on laser cutting. The laser was too strong so it went through the edge and outline. And the problem was that the model in illustrator had double layer so they went around twice. Next time I should check before laser cutting.
Setting my object and projector (in second floor). Checking my motion in Arduino. Outlining two views that is set in the motor. Trying to outline it as close as possible.
Process of composition: Continue Stepper test
After rendering my animation, I started to match my object and test out the time in Arduino. I was worried that my object would not match with the rendering because when I first matched my object in Maya, it had some space that would not match. But, thank god it is not too different, but I would like to figure out why my rotation did not work perfectly.
I used zig zag pattern to test out projection mapping because I was inspired by illusion and that it gives confusion to people when they look at it too much.
Process of composition: Animation test
Testing out different effects to get to know what is what and also what I can do to express my concept. For this I used phong and bulge to see the movement of the effect. Testing out different effect using texture but also colors. I’m using bold primary colors. I wanted to see movements in all the texture. How the flow works in different faces of the object.
Maya is very complicated. If you don’t organize all the effects you made, it’s really hard to keep on track. So, I opened hypershade and named all the effects I was going to use and then assigned it to the object. It was so much easier to do.
Process of composition: Servo & Switch test
http://arduino.sundh.com/2012/06/detect-switch-on-digitalread/
Bought all the materials (switch, wire, bread board, electrical resistance, etc.). I followed the steps that was online.
Followed the steps online but my servor would not respond to the switch. I kept on trying to figure out how the switch works. Very frustrating because it would not work even though I following the steps. Found a new way that my switch works. But the funny part is that this was not the way people usually follow. This was actually a mistake that I found that the switch works. I’m just thankful that it works.
Chapter Three. Final Model
This is my final concept. I wanted to express growth of some sort of bacteria feel. But wanted to show difference between the faces of object. So, for the edge, I have expressed time by making patterns that symbolizes arrow. And for the inside faces in the middle, I wanted to show bacteria growing more and shrinking step by step. Outside faces are the movement of the bacteria.
