hi guys,

how do i export color stls using toxilibs? i found this topic here: http://processing.org/discourse/yabb2/YaBB.pl?num=1268405776 but i could not get the example to work. I'm running the latest version of toxilibs. After some tweaking, this is as far as i've got. the error is at line 34 where i try to retrieve the vertices of the faces.

many thanks

exporting very small circles turning into hexagons

hi guys,

I'm currently working on a large project that requires me to zoom into a map, but i've run into the issue of when exporting circles 0.1 pt in radius they convert to hexagons in pdf. I'm reluctant to scale the whole script because it would mean rescaling a large quantity of csv files.

Is there a way to export the files as circles?

the image below is a rescaled ellipse of 0.1 pt radius.
2. import processing.pdf.*;
3. boolean record;
5. void setup(){
6. size(500,500, P3D);
7. smooth();
8. }
11. void draw(){
12. if (record) {
13. // Note that #### will be replaced with the frame number. Fancy!
14. beginRaw(PDF, "frame-####.pdf");
15. }
16. ellipse(width/2, height/2, 0.2, 0.2);
18. if (record) {
19. endRaw();
20. record = false;
21. }
23. }
25. void keyPressed(){
26. if (key == 's'| key=='S') {
27. record = true;
28. // saveFrame("combine15K-####.png");
29. }
30. }

Hi guys,

i'm working on a code but i've run into a problem when i try to run ArrayList.set

the code runs fine with arrayList.add but i'm unable to use this since i'm in void draw and it continuously adds.

I've added a a series of values in the void setup so that the set values don't start blank.

Many thanks,

hi guys,

i have a set of 2d arrays which i've stored in an arraylist. How do i combine the 2d arrays?

the script is a bit lengthy so i dont want to post the whole thing up...
2. //xs is the int[][] arraylist
3. //finalSum is a variable stored in the class
4. for(int i=0;i<xs.size();i++){
5. int valval[][] = new int[imgwidth][imgheight];
6. valval = xs.get(i);
7. for(int j=0;j<imgwidth;j++){
8. for(int k=0;k<imgheight;k++){
10. finalSum[j][k] = finalSum[j][k] + valval[j][k];
11. }
12. }
13. }

control P5 - adjusting background update settings

Hi guys,

I'm working on a project which requires me to draw in the control window, then save the images out using saveFrame. I'm unable to draw in the control window because i can't seem to get the control window to stop updating (setDrawBackground not working??)

here's the basic outline, thanks in advance
2. import controlP5.*;
3. ControlWindow controlwindow;
4. ControlWindowCanvas cc;
5. ControlP5 controlP5;
7. void setup() {
8. size(1024, 768);
9. controlP5 = new ControlP5(this);
10. controlwindow = controlP5.addControlWindow("controlP5window", 100, 100, 400, 768);
11. controlwindow.setBackground(color (0));
12. controlwindow.setDrawBackground(false); //this not working?
14. cc=new EmpCan();
15. cc.post();
16. controlwindow.addCanvas(cc);
17. }
19. void draw() {
20. }
22. class EmpCan extends ControlWindowCanvas {
23. public void setup(PApplet theApplet) {
24. theApplet.background(0);
25. }
26. public void draw(PApplet theApplet) {
28. //create an image(from processing site)
29. PImage img = createImage(66, 66, RGB);
30. img.loadPixels();
31. for (int i = 0; i < img.pixels.length; i++) {
32. img.pixels[i] = color(0, 90, 102);
33. }
34. img.updatePixels();
35. //add it to draw
36. image(img, 17, 17);
37. //add it to canvas
38. theApplet.image(img,0,0);
39. theApplet.image(img, theApplet.width, theApplet.width);
41. //draw ellipses in the Control Window(NOT WORKING)
42. if (theApplet.mousePressed) {
43. theApplet.fill(255, 100, 0);
44. theApplet.ellipse(theApplet.mouseX, theApplet.mouseY, 20, 20);
45. }
47. //draw ellipses in the main window(WORKS)
48. if (theApplet.mousePressed) {
49. fill(255, 100, 0);
50. ellipse(theApplet.mouseX, theApplet.mouseY, 20, 20);
52. }
54. //this doesn't work either?
55. }
56. public void mouseReleased(PApplet theApplet) {
57. saveFrame();
58. println("yay");
59. }
60. }

counting problem

hi guys,

i think my friend tried to post this earlier but didn't explain it well...

i'm trying to write a script which seperates a list into those which are at X pixels away and those are more than X pixels away then count both arraylists. I've been trying this for quite some time but cant get the points grouped up correctly, any help would be appreciated!

i'm using toxic libs geometry library for the vector math.
1. import toxi.geom.*;
2. PFont f;
3. Closestpoint AdrClosePoint;
4. ArrayList pointCollection;
5. ArrayList templist;
7. void setup() {
8. size (1400, 900);
  background(255);
  
  f = createFont("Arial", 12, true);
  textFont(f);
9. f = createFont("Arial",16,true); // Loading font
  
  pointCollection = new ArrayList();
  
  templist = new ArrayList();
10. for (int i = 0; i<1000; i++){
      Vec3D origin = new Vec3D(random(width), random(height), 0);
      Closestpoint mypoint = new Closestpoint(origin);
      pointCollection.add(mypoint);
  }
  }
11. void draw() {
  for (int i = 0; i< pointCollection.size(); i++){
      Closestpoint cp = (Closestpoint) pointCollection.get(i);
      cp.display();
      cp.distancenear();
12. }
  text(pointCollection.size()- templist.size(), width/2, height/2);
1. class Closestpoint {
2. //global variables
3. Vec3D pos = new Vec3D (0, 0, 0);
6. //constructor
  Closestpoint(Vec3D _pos) {
  pos = _pos;
  }
7. //functions
8. void display() {
9.     stroke(0);
      strokeWeight(1);
      point(pos.x, pos.y);
  }
10. void distancenear() {
11. int count=0;
12.     for (int i = 0; i < pointCollection.size();i++) {
        Closestpoint other = (Closestpoint) pointCollection.get(i);
        float distance = pos.distanceTo(other.pos);
        if ( distance >0 && distance < 20) {
          fill(0,0,255);
          ellipse(pos.x, pos.y, 20,20);
          if(count < pointCollection.size()){
          templist.add(pos);
          count++;
          }
  
        }else{
           getpoints(distance, pos, other.pos);
        }
      }
  }
  }
13. void getpoints(float distance, Vec3D pos, Vec3D other) {
14. fill(255, 100, 0);
15. ellipse(pos.x, pos.y, 10, 10);
16. }
}
