Submission 242 - Project 2

Here is my final submission for Project 2

CODE

YRES = 700 ##HEIGHT is 700
centerX = random(XRES/2-200,XRES-200) ##Center of the planet (random between the middle of the sketch to 200 units around)

for i in range(1, XRES):
angle = random(0.,PI*2)
x = i*1.618*sin(angle) ##golden ratio applied
y = i*1.618*cos(angle)
ellipse(centerX+x,centerY+y,data[i]/5,data[i]/5) ##main circles make the galaxy
ellipse(centerX+2*x,centerY+2*y,data[i]/7,data[i]/7) ##smaller circles make it more interesting

def filter(data):
for i in range(1,XRES-1):
data[i]=0.5*(data[i-1] + data[i+1]) ##Median filter for data

def draw():
filter(randata)
if (4*frameCount)<(2500): ##the amount of circles and speed of the sketch
plot(randata, 4*frameCount)
