How can I make something like a 3D map
Apr 29th, 2008, 8:28am  
Hey!
I'm wondering how I can code something generative that looks like a 3D map. Go here to understand what I mean Wink

It looks like a complex 3D model whose outlines are drawn individually for every z-layer. But I just don't know how to realize it. Maybe someone's got a hint?

Thx A.P.

I don't believe that this is 3d. A simple solution is to use points on a bezier curve (http://processing.org/reference/bezierPoint_.html) and adding a little noise to it. This is a little non tested example of my idea.

Code:

bezier(85, 20, 10, 10, 90, 90, 15, 80);
ellipseMode(CENTER);
int lastX=85;
int lastY=20;
int steps = 10;
for (int i = 0; i <= steps; i++) {
  float t = i / float(steps);
  float x = bezierPoint(85, 10*noise(t), 90*noise(t), 15, t);
  float y = bezierPoint(20, 10*noise(t), 90*noise(t), 80, t);
  line(lastX, lastY,x, y);
  lastX=x;
  lastY=y;
}
