Musical Circles | ICM #3

This week we were asked to start working with rule-based animation, motion, and interaction. I partnered with Aaron Montoya-Moraga and worked on a series of concentric musical circles based partially on the advanced rollover button example that was made available to us (http://bit.ly/1NM53NR). We began by basically replicating the advanced rollover buttons but altered the shapes and drew them using a for loop:

for (var k = 0; k < 5; k++) { fill(colors[k]); ellipse(width / 2, height / 2, diameters[k], diameters[k]); This gave us a greyscale and silent version of what our final project would look like.

Each circle is always fading to black, however when the mouse hovers over any individual circle it is changed to white allowing the circle to slowly fade black as the mouse is moved between other circles. 

Eventually we were able to add in fading colors using arrays. We haven’t covered arrays in class yet but with some trial and error we got the circles to change color and opacity based on mouse position using the same kind of looped fading mechanism. 

Lastly we included sound. Aaron and I struggled with this for a while but eventually Arron was able to get some help from ITP resident Jason Segal and now the sound can fade in and out along with the color changes. Some adjustments to the starting position and fade were made to accommodate the sound functions.
