Hi!

I want to make a PDF export of a 3d scene in ortho view.
It works so far, but somehow the display order in the PDF it totally wrong.


(left: screenshot of the sketch, right: pdf-output)

Any idea, how to fix that??
I tried to play around with scaling the view in x, y & z (z.B.scale(-1, 1 1)), but that didn't work.

this is the code of the sketch.
I took the PDF stuff out of the processing example:

1. import processing.pdf.*;
   import processing.opengl.*;
   
   boolean record;
   boolean[][][] filled;
   
   void setup() {
     size(1000, 1000, P3D); smooth();
     strokeWeight(1);
     ortho(0, width, 0, height,-10, 10);
    
     filled = new boolean[10][10][5];
     for (int i = 0; i < filled.length; i++)
       for (int j = 0; j < filled[0].length; j++)
         for (int k = 0; k < filled[0][0].length; k++)
           if (random(1) < 0.4) filled[i][j][k] = true;
   }
   
   void draw() {
     if (mousePressed) record = true;
     if (record) {// set up PGraphicsPDF for use with beginRaw()
       PGraphicsPDF pdf = (PGraphicsPDF)beginRaw(PDF, "pdf_complex_out.pdf");
       //pdf.ortho(0, width, 0, height, 1000, -1000);
       // set default Illustrator stroke styles and paint background rect.
       pdf.strokeJoin(MITER);
       pdf.strokeCap(SQUARE);
       pdf.fill(255);
       pdf.noStroke();
       pdf.rect(0,0, width,height);
      
       strokeWeight(1);
     }
    
     background(255); directionalLight(255, 255, 255, 1, 4, -3); ambientLight(155, 155, 155);
   
     translate(width, height, 0);
     rotateX(-PI/6);
     rotateY(PI/3);
     scale(2);
   
     for (int i = 0; i < filled.length; i++)
       for (int j = 0; j < filled[0].length; j++)
         for (int k = 0; k < filled[0][0].length; k++) {
           if (filled[i][j][k]){
             pushMatrix();
             translate(i * 10, j * 10, k * 10);
             //scale(-1, 1, 1);
             box(10);
             popMatrix();
           } else {
           }
         }
        
     if (record) {record = false; endRaw();}
   }
