Simple example of how to generate meshes with Processing and then output them to STL using unlekkerLib.

import unlekker.util.*;
import unlekker.geom.*;
import unlekker.data.*;

import processing.opengl.*;

boolean doSTL=false;

void setup() {
  size(400,400, OPENGL);
}

void draw() {
  background(100);

  if(doSTL) {
    beginRaw("unlekker.data.STL","cyl.stl");
  }

  translate(width/2, height/2, 0);
  rotateY(radians(frameCount));
  rotateX(radians(frameCount));

  fill(255,255,255);

  for(int i=0; i<100; i++) {
    pushMatrix();
    translate(random(-300,300),random(-300,300),random(-300,300));
    rotateY(random(PI*2));
    rotateX(random(PI*2));
    cylinder(50,random(50,200));
    popMatrix();
  }

  if(doSTL) {
    endRaw();
    doSTL=false;
  }

}

void keyPressed() {
  if(key=='s') doSTL=true;
}

void cylinder(float w,float h) {
  float px,pz;

  beginShape(QUAD_STRIP);
  for(float i=0; i<13; i++) {
    px=cos(radians(i*30))*w;
    pz=sin(radians(i*30))*w;
    vertex(px,-h,pz);
    vertex(px,h,pz);
  }
  endShape();

  beginShape(TRIANGLE_FAN);
  vertex(0,-h,0);
  for(float i=12; i>-1; i–) {
    px=cos(radians(i*30))*w;
    pz=sin(radians(i*30))*w;
    vertex(px,-h,pz);
  }
  endShape();

  beginShape(TRIANGLE_FAN);
  vertex(0,h,0);
  for(float i=0; i<13; i++) {
    px=cos(radians(i*30))*w;
    pz=sin(radians(i*30))*w;
    vertex(px,h,pz);
  }
  endShape();
}

The Generator.x 2.0: Beyond the Screen workshop and exhibition kicks off in Berlin this Thursday. In addition to the workshop there will be two evenings of presentations open to the general public, intended to bring the topics of the workshop to a larger audience.

The presentations will take place at the Ballhaus Naunynstrasse, which is also the venue for the workshop. If you’re in Berlin I hope to see you there!

Generator.x 2.0: Presentations #1 - Thu 24 Jan, 19:00 - 21:00

• Keynote: Marius Watz [NO]
• Boris Müller [DE]
• Satoru Sugihara - Morphosis [JP/US]
• Eno Henze [DE]

Generator.x 2.0: Presentations #2 - Mon 28 Jan, 19:00 - 21:00

• Aram Bartholl [DE]
• David Dessens [FR/DE]
• Tim Schork - MESNE [DE/AUS]
• Skylar Tibbits - Theverymany [US]

See the Club Transmediale site for a full list of Generator.x 2.0 events. Documentation of the event will be posted on the Generator.x blog and Flickr group as it becomes available.
