Project 2

From last class, Bowei and I got many feedbacks on how to make this project to visually looks more interesting. And I took a few of approachable feedbacks, and executed some modification and optimization.

The first thing that we optimization is to reduce the amount of particles, and add 2 more Perlin noise spaces with various noise speed. And use the new Perlin noise vector space as acceleration guide for 2 different size particles. By doing that, not only we wish to eliminate the unnecessary particles which were overlapping in the previous version; but also the particles in different sizes could generate an illusionary depth. To enhance that, I changed the color changing loop algorithm. Figure 1 shows the optimized particle field in its default state. (no incoming data from accelerometer)

This optimization speeds up the program, and created a lot more interesting visual effects compared to merely adding more new particles. In addition, it is much easier to actually create a 3D Perlin space and use a fourth dimension as its time to retrieve the vector value of each chunk of the space. On the physical side, Minjun and I talked about a setup I saw when I was in a club at Halloween, and both agreed it is cool and we could break this setup down into a LED panel, a digital output which we already have, and a glove controller with some performative elements. Video 1 is a short clip of that.

I was working on the LED panel, and Bowei was trying to use ADPS-9960 with its RGB detecting function to work, so that the colors of my particles could change along with the environment. 


I made the LED Panel that mimics the code with HC-SR04 the closer an object gets the faster the particles move.
