Hello,

I am trying to load a SVG shape into processing and display it in a 3D like style. IS this possible ?

I downloaded some 3D Contribution libs from the webpage but they are not doing what I want and

using the PShape's rotateZ, Y ,X functions make me see vertices and edges .

Any ideas.

This will be a SVG shape with 50 zones and they also need to be extruded on some inputs.

Thanks.

Hello I have the following class and what I am trying to do is rotate the circle and square around the center point.

Please help.
2. class arrow {
3. float x;
4. float y;
5. float a;
6. float iAlpha;
8. float scaleUpF = 1.01;
9. float scaleDownF = 0.99;
10. float fRotation;
11. float vx = 0;
17. arrow (float cX, float cY, float cA, float ciAlpha) {
18. x= cX;
19. y= cY;
20. a= cA;
21. iAlpha = ciAlpha;
22. fRotation = 0;
23. vx = 0;
24. }
27. void display () {
28. pushMatrix();
29. translate(width/2+x+vx, height/2+x+vx);
30. fill(170,170,170,iAlpha);
31. rotate( radians(fRotation) );
32. rect (x + vx,y ,3*a,a);
33. ellipse(x + vx, y, 5 ,5 );
34. // x1 y1, x2 y2, x3 y3
35. triangle (x+vx+(1.5*a), -a, x+vx+(1.5*a), a, vx+x+4*a, y);
36. popMatrix();
37. }
39. void checkKey()
40. {
42. if(keyPressed == true && key == 's' || key == 'S') {
43. a *= scaleUpF;
45. }
46. if(keyPressed == true && key == 'x' || key == 'X') {
47. a *= scaleDownF;
48. }
50. if(keyPressed == true && key == 'a' || key == 'A')
51. {
52. iAlpha *= scaleUpF;
53. }
54. else if(keyPressed == true && key == 'z' || key == 'Z')
55. {
56. iAlpha *= scaleDownF;
57. }
58. else if(keyPressed == true && key == CODED && keyCode == LEFT) {
59. fRotation += scaleUpF;
60. }
61. else if(keyPressed == true && key == CODED && keyCode == RIGHT)
62. {
63. fRotation -= scaleUpF;
64. }
65. else if(keyPressed == true && key == CODED && keyCode == UP)
66. {
67. vx += 1;
68. }
69. else if(keyPressed == true && key == CODED && keyCode == DOWN)
70. {
71. vx -= 1;
72. }
73. }
77. void keyReleased() {
78. if( vx > 0) vx = 0;
80. }
81. }

Reading a file and word counting.

Hello,
Im new to processing but I really like it so spending a few hours everyday to improve myself.
What I am trying to achive now is, I am trying to read a txt file and count the different words inside it.
The next step will be visualising this data.

I am adding the code I am using:
This is the main sketch file.
1. String[] lines; // Line Array
  int[] wordCount = new int[100];
  ArrayList wordsArray;
  
  int wordCounter = 0;
  int lineIndex = 0;
  int charIndex = 0;
  
  void setup() {
  wordsArray = new ArrayList();
  size(400, 400);
  background(0);
  noStroke();
  frameRate(10);
  lines = loadStrings("lipsum.txt");
  noLoop();
  smooth();
  }
  
  void draw() {
  while(lineIndex < lines.length) {
      String[] words = splitTokens(lines[lineIndex], " ");
      for(int i=0; i < words.length; i++) {
           wordsArray.add(new newWord(words[i],1));
           //wordsArray[wordCounter] = words[i];
           wordCount[wordCounter] = 0;
           println(words[i]);
           wordCounter++;
        }
      lineIndex++;
  
  }
  println("Word Count:"+wordsArray.size());
  // for(int i = 0; i<wordsArray.length; i++) {
  //    if(wordsArray[i] != null) {
  //     ellipse(10+(25 * i), height/2, wordsArray[i].length()*2, wordsArray[i].length()*2);
  //    }
  // }
  
  for(int i=0; i < wordCounter; i++) {
      for(int j=0; j < wordCounter; j++) {
        if((wordsArray.get(j)).equals(wordsArray.get(i))) {
          println(wordsArray.get(j));
           wordCount[i]++;
  
        }
        //String[] word = match(wordsArray.get(j), wordsArray.get(i);
  //      if(word != null) {
  //
  //
  //          //word = null;
  //      } else {
  //          //print(" No match ");
  //          //word = null;
  //    }
      //checkWord(wordsArray[i]);
  }
  }
  
  for(int i = 0; i<wordCounter; i++) {
      println(wordCount[i]);
  }
  } // Draw Son
and this is the class. Again Im new to processing and Im new to classes.
1. class newWord {
  
  String word;
  int count;
  
  newWord(String wordTemp, int countTemp) {
  word = trim(wordTemp);
  count = countTemp;
  
  }
  
  }
My first problem is I can not reach the contents of an ArrayList, when I use println it gives me:
strings$newWord@648016 and such.

can someone please direct me to the correct direction.
thanks
miki
