I'm trying to process some 3d object with the 3d obj loader library from saito ( https://code.google.com/p/saitoobjloader/) in order to stream it via the Syphon library ( http://codeanticode.wordpress.com/2012/02/21/syphon-client-working-in-processing/).

With Processing, I usually create a PGraphics in which I draw all my elements that I'll send to my Syphon Client.

But as the draw method from the saito.objloader library is  directly  drawing the 3d model in the main PApplet, I can't find how to draw directly in my canvas created below (the PGraphics elements I'm trying to send via Syphon).

Here's a copy of my code without the Syphon implementation:

2. import saito.objloader.*;
3. import ddf.minim.spi.*;
4. import ddf.minim.signals.*;
5. import ddf.minim.*;
6. import ddf.minim.analysis.*;
7. import ddf.minim.ugens.*;
8. import ddf.minim.effects.*;
9. 
   
10. import codeanticode.syphon.*;
11. 
    
12. Minim minim;
13. AudioInput in;
14. FFT fft;
15. PGraphics canvas;
16. SyphonServer server;
17. OBJModel model;
18. 
    
19. void setup()
20. {
21.     size(600, 600, P3D);
22.     server = new SyphonServer(this, "Frame");
23.     
24.     minim = new Minim(this);
25.     in = minim.getLineIn(Minim.STEREO, 512);
26.     fft = new FFT(in.bufferSize(), in.sampleRate());
27.   
28.     model = new OBJModel(this, "MaleLow.obj", "relative");
29.     model.disableDebug();
30.     
31.     model.shapeMode(POLYGON);
32. 
    
33.     model.scale(8);
34. 
    
35.     noStroke();
36. }
37. void stop() {
38.   in.close();
39.   minim.stop();
40.   super.stop();
41. }
42. float inc = 0;
43. void draw()
44. {
45.     inc++;
46.     background(32);
47.     lights();
48.     fft.forward(in.mix);
49.     
50.     if(in.mix.level()*2550<240) {
51.             model.enableMaterial();
52.         } 
53.     else {
54.             model.disableMaterial();
55.     }
56.     
57.     stroke(fft.getBand(150)*100, fft.getBand(150)*150, fft.getBand(150)*100);
58. 
    
59.     directionalLight(0,0,fft.getBand(250)*2550, 100, 10, 0);
60.     directionalLight(0,0,fft.getBand(250)*2550, -100, 10, 0);
61.     
62.     //this will do nothing until the model material is turned off
63.     fill(255,0,255,90);
64. 
    
65.     pushMatrix();
66.     translate(width/2, 410, 360);
67.     rotateX(-0.6);
68.     rotateY(radians(inc*0.1));
69.     
70.     model.draw();
71. 
    
72.     popMatrix();
73.     
74. }

I thank you in advance for you help and wisdom !
