IDAS 2015 Media Environment Stuio I
Projection Mapping Digital Media Design Jong-won Lee appsdesign@naver.com
Step #01
Defining the Shape
By learning Maya, I could make shapes in 3D space.
Using laser cutter and Perakura program, it is possible to make a shape with it.
Searching the right shape and starting to develop the concept for the class.
Step #02
Lighten the Projection
Using Maya and After Effects to do the projection mapping. It is quite interesting to projection map on the small object.
Step #03
Motors and Arduino
Using Arduino, the object starts to rotate. I use a Stepper motor, a Motorshield from Adafruit, and Arduino. Using basic program example from the Arduino Library. It is easy to start.
Step #04
Planning the Exhibition
There was a problem on motion and video syncing. The Stepper Motor is not sending its rotation position to Arduino. So I was thinking of using a Limiter Switch to get the position value. Also, by using Mobile device and Bluetooth, its possible to not carry the computer. So I made an app on iPhone with the movie sequence is on.
I also find that the position and location of the camera on Maya is very important. So I check the real position of the degree of Projector and the Object.
Step #05
Sync the Motion and Movie Sequence
As I planned all the way to here, the movie sequence and Arduino doesn’t match well. So I put the Servo motor and Potentiometer to match the hand control and motor movement. Also sending the motor-value signal to Processing, it is possible to control the movie sequence too.
Step #06
Planing for the Final Exhibition
I decided to use simple shape rotation and moving object (animation) inside of the box. Using Servo Motor and Potentiometer to rotate it precisely.
Step #07
Final Animation on Maya
This is the final image sequence for the final exhibition.
Step #08
BLISS Exhibition
It was exhibited on the BLISS exhibition in IDAS of Hong Ik University.
