Hi,

first, sorry for my bad english.....well..... i'm trying to import a 3D object with the saito library on processing 1.5.1. But it doesn't work, i've allways this error :
The constructor OBJModel(obj_loader, String, String, int) is undefined

I tried on processing 1.2.1 and it works fine, but i need to work with the 1.5.1 .

it's the example code from saito website :

1. import saito.objloader.*;
2. // declare that we need a OBJModel and we'll be calling it "model"
3. OBJModel model;
4. float rotX;
5. float rotY; // these booleans will be used to turn on and off bits of the OBJModel
6. boolean bTexture = true;
7. boolean bStroke = false;
8. boolean bMaterial = true;
9. void setup() {
10.   size(600, 600, P3D);
11.   // making an object called "model" that is a new instance of OBJModel
12.   model = new OBJModel(this, "CHAMBRANLE.obj", "relative", TRIANGLES); 
13.   // turning on the debug output (it's all the stuff that spews out in the black box down the bottom)
14.   model.enableDebug();
15.   model.scale(8);
16.   noStroke();
17. }
18. void draw() {
19.   background(32);
20.   lights(); //this will do nothing until the model material is turned off
21.   fill(255, 0, 255);
22.   pushMatrix();
23.   translate(width/2, height/2, 0);
24.   rotateX(rotY);
25.   rotateY(rotX);
26.   model.draw();
27.   popMatrix();
28. }
29. void keyPressed() {
30.   // turns on and off the texture listed in .mtl file
31.   if (key == 't') {
32.     if (!bTexture) {
33.       model.enableTexture();
34.       bTexture = true;
35.     }
36.     else {
37.       model.disableTexture();
38.       bTexture = false;
39.     }
40.   }
41.   else if (key == 'm') {
42.     // turns on and off the material listed in .mtl file
43.     if (!bMaterial) {
44.       model.enableMaterial();
45.       bMaterial = true;
46.     }
47.     else {
48.       model.disableMaterial();
49.       bMaterial = false;
50.     }
51.   }
52.   else if (key == 's') {
53.     if (!bStroke) {
54.       stroke(10, 10, 10);
55.       bStroke = true;
56.     }
57.     else {
58.       noStroke();
59.       bStroke = false;
60.     }
61.   }
62.   // the follwing changes the render modes
63.   // POINTS mode is a little flakey in OPENGL (known processing bug)
64.   // the best one to use is the one you exported the obj as
65.   // when in doubt try TRIANGLES or POLYGON
66.   else if (key=='1') {
67.     stroke(10, 10, 10);
68.     bStroke = true;
69.     model.shapeMode(POINTS);
70.   }
71.   else if (key=='2') {
72.     stroke(10, 10, 10);
73.     bStroke = true;
74.     model.shapeMode(LINES);
75.   }
76.   else if (key=='3') {
77.     model.shapeMode(TRIANGLES);
78.   }
79.   else if (key=='4') {
80.     model.shapeMode(POLYGON);
81.   }
82.   else if (key=='5') {
83.     model.shapeMode(TRIANGLE_STRIP);
84.   }
85.   else if (key=='6') {
86.     model.shapeMode(QUADS);
87.   }
88.   else if (key=='7') {
89.     model.shapeMode(QUAD_STRIP);
90.   }
91. }
92. void mouseDragged() {
93.   rotX += (mouseX - pmouseX) * 0.01;
94.   rotY -= (mouseY - pmouseY) * 0.01;
95. }

I think my library is at the good place with the data and  i work on mac os 10.6.8...

thank for yours helps....
