Voronoi noise is cool

I’ve been playing with procedural world generation for a while now (because I’m lazy when it comes to level design), which of course means noise functions!

I’m really starting to dig voronoi noise after looking at some of the stuff you can do with it So, I hacked together a voronoi noise previewer:

(Next step: making it actually update in real time. It’s slow!)


Made this goofing around to see if I could compress an entire python program into a single expression. Who said Python Lambda’s aren’t powerful?!

    not globals().__setitem__('sys', __import__('sys'))
    and not globals().__setitem__('this', sys.modules[globals()['__name__']])
    and not globals().__setitem__('time', __import__('time'))
    [setattr(this, k, v) for k,v in {
            'set_color': (lambda c: w(['*', ' '][c])),
            'abs': (lambda t: (t + (t >> 31)) ^ (t >> 31)),
            'w': sys.stdout.write,
            'smash': (lambda t: -((t * -1) >> 31)),
            'color': (lambda n,k: set_color(smash (k & (n - k)))),
            'col': (lambda n, k: k <= n and not color(n,k) and col(n,k + 1)),
            'row': (lambda n: not w(' ' * (40-abs(n/2)))
                              and (col(abs(n), 0) or True)
                              and not w("\n")
                              and (abs(n) < 63 or n < 0)
                              and not time.sleep(0.05)
                              and row(n+1)),
            'triangle': lambda: row(-60) or True and triangle()
        }.items() ] and triangle() )()
