FABRICATION AND PRODUCTION:

  1. Prototype:
    1. From the very beginning of the project I already had a clear sense of how the spotlight will be structured, it will have two potentiometers that move along with the turning of the spotlight and they will provide input for the location of the light.
        1. With some cardboard, wires, hot glue and some real difficult welding the prototype of the spotlight is done! (But it was not working……
    2. For the final result with the suggestion from Andy, I decided to use lazier cut wood for the base and 3D print the body and the handle of the spotlight.
    3. After printing all the parts are put together with hot glue.
  2. Coding
    1. The major part of this project is on the coding, it involves image processing, audio and visual affects. 
    2. Fist of all, as described in the design the project is in stages, therefore a timing system is crucial, so millis is crucial, all steps are built around the timeline. 
    3. To display the spotlight affect I begin with filters I wished to apply the background with a dark filter and where my light shine the filter will be removed. However, in practice I realized this is beyond my reach and for a more blurred affect I chooses to use the pixels get to create a bubble visual affect. 
    4. To have an immersive environment sound is a must, that’s why I incorporated four sound tracks in the program.
