Nodebox
Nodebox is a Mac/Python app for programatically creating graphics and animation, like Processing but with less power but also much simpler to use. I’m currently working on a webapp, Bubble (Bayesian User-Based Biological Learning Environment, natch) that’s written entirely in python. The actual bayesian learning happens using PEBL (Python Environment for Bayesian Learning (see a trend here?)) and the web interface and database are created using the python web framework, Turbogears. So, rather than introducing Photoshop into this all-python party, I decided to create the logo for Bubble using NodeBox. This is the initial draft:
And it’s created using this script:
size(800, 400) fill(0) rect(0,0,WIDTH,HEIGHT) from math import sin, cos, tan, log10 cX = 1 cY = 3.9 x1 = x2 = 100 y1 = y2 = 20 helix1 = [] helix2 = [] GENE, BINARY = 1,-1 for i in range(128): x1 += cos(cY)*8 y1 += log10(cX)*random(2.0,2.2) + sin(cX) * 1 s1 = 12 + cos(cX)*6 helix1.append((x1,y1,s1)) x2 += sin(cY + 60)*8 y2 += log10(cX)*random(2.0,2.2) + cos(cX) * 1 s2 = 12 + sin(cX-45)*6 helix2.append((x2,y2,s2)) cX += .2 cY += random(.145, .17) def draw(x,y,s,c): fill(random(), 0.8, 0.9*c, random(.15,.3)) oval(x-s/2, y-s/2, s, s*1.2) fill(random(), 0.8, 0.9*c, random(.8,.9)) fontsize(s) if c is GENE: text(choice(['A', 'G', 'C', 'T']), x-s/2,y+s/2.5) elif c is BINARY: text(choice(['0', '1']), x-s/2.5, y+s/2.5) for i,(h1,h2) in enumerate(zip(helix1,helix2)): if i < 20: continue x1,y1,s1 = h1 x2,y2,s2 = h2 if (i-20)%20 < 10 and (i-20)%20 > 2: draw(x1,y1,s1, GENE) draw(x2,y2,s2, BINARY) else: draw(x2,y2,s2, BINARY) draw(x1,y1,s1, GENE) fontsize(150) font("Chalkboard") path = textpath("Bubble", 220, 280) beginclip(path) for i in range(1500): fill(random(), 0.8, 0.9, random(.3, .6)) x = random(220,800) y = random(100,300) oval(x,y, random(10,20), random(10,20)) endclip()
