I'd like to ask if there is a way to control the levels of recursion. 

For example i want to change the appearance of the first branch. Then the other 3 childs have a different draw method. Then his childs have different draw methods.

How is that possible logically?

My code is down below;

Thanks in advance,

Met.

2. int _maxLevels = 3;
3. int _numChildren = 3; 
4. Branch _trunk;
5. 
   
6. void setup() {
7.   size(900, 900);
8.   smooth();
9.   _trunk = new Branch(1, 0, width/2, 50);
10.   _trunk.drawMe();
11. }
12. 
    
13. 
    
14. 
    
15. class Branch {
16.   float level, index;
17.   float x, y;
18.   float endx, endy;
19.   Branch[] children = new Branch[0];
20. 
    
21.   Branch(float lev, float ind, float ex, float why) {
22.     level = lev;
23.     index = ind;
24.     updateMe(ex, why);
25. 
    
26.     if (level < _maxLevels) {
27.       children = new Branch[_numChildren];
28.       for (int x = 0; x < _numChildren; x++) {
29.         children[x] = new Branch(level+1, x, endx, endy);
30.       }
31.     }
32.   }
33. 
    
34.   void updateMe(float ex, float why) {
35.     x = ex;
36.     y = why;
37.     endx = x + (level * random(100) - 50);
38.     endy = y + 50 + (level * random(50));
39.   }
40. 
    
41.   void drawMe() {
42.     strokeWeight(_maxLevels - level + 1);
43.     line(x, y, endx, endy);
44.     ellipse(x, y, 5, 5);
45.     for (int i = 0; i < children.length; i++) {
46.       children[i].drawMe();
47.     }
48.   }
49. }

For a school project i'm trying to use Delicious API in Processing platform.

I have a question,

So far i can visualize the 'Titles' and 'Tags' of individual posts into the processing canvas.

What i want to do is, i want to get a specific get like "design" and scatter the posts' titles around that tag and draw a line from center to each of them... like network graphs, sort of.

But in the documentation, i cannot find a way to get a single specific Tag in the getTag() method.

The link to the documentation is here, (getTag) http://delicious-java.sourceforge.net/del/icio/us/beans/Post.html#getTag()

get the tag 'design' and type the posts' titles that contains 'design' tag around it randomly.

What is the logic behind it, can you explain it to me?

My code looks like this

2. Delicious delicious;
3. PFont font;
4. 
   
5. String title;
6. 
   
7. void setup() {
8. 
   
9.   font = loadFont("HelveticaNeue-9.vlw");
10.   textFont(font);
11. 
    
12.   size(800, 1000);
13. 
    
14.   // Initiate Delicious object. Replace username and password with your own info.
15.   delicious=new Delicious("Textfield", "met7052");
16. 
    
17.   // Retrieve recent posts. The result is a List object containing the 
18.   // Posts as del.icio.us.beans.Post objects. We'll use List.toArray() to
19.   // give us an array of the Objects in the List.
20.   Object [] o=delicious.getRecentPosts("", 150).toArray();
21. 
    
22. 
    
23. 
    
24.   // Uncomment the following line to get all posts.
25.   //  Object [] o=delicious.getAllPosts().toArray();
26. 
    
27. 
    
28.   // Convert the Objects to Posts
29.   Post [] posts=new Post[o.length];
30.   for (int i=0; i<posts.length; i++) { 
31.     posts[i]=(Post)o[i];
32.   }
33. 
    
34.   // Print the posts
35.   println("Del.icio.us posts retrieved: "+posts.length);
36.   for (int i=0; i<posts.length; i++) {
37.   //  println(i+": "+posts[i]);
38. 
    
39.     pushMatrix();
40.     translate(50, 50);
41. 
    
42.     float descriptionWidth = textWidth(posts[i].getDescription());
43.     float tagWidth = textWidth(posts[i].getTag());
44.     int margin = 30;
45. 
    
46.     fill(50);
47.     text(posts[i].getDescription(), 0, 20*i);
48.      //text(posts[i].getTime(), descriptionWidth + margin, 20*i);
49.     fill(135);
50.     text(posts[i].getTag(), descriptionWidth + margin, 20*i);
51.     popMatrix();
52.   }
53. }

Thanks a bunch. Met.

I've been wondering how can i get a proper export as a PDF file in a non-refreshing background sketch. My particles just draw their way around and creates a composition. Now when i do  Many Frames Into One File (With Screen Display) it draws all the frames so pdf just messes up the computer. What i want is to just capture the one frame, the exact look on the sketch. When i try  Single Frame from an Animation (With Screen Display) it just renders my particles without any drawings they made.

Or is there even a way to set a size parameter for a tiff in saveFrame(); function. for example, i got this 500x500 sketch and i want to get a tiff of it for 2000x2000?

I Hope i made myself clear, 

Thank you,

Metin.
