DXF library not exporting?

rossdickinson

Hi, I'm using the computational geometry library and am trying to export to DXF. I set a keyPress for the export but I'm hitting the key and nothing is being generated in the sketch folder. Any help would be very appreciated, thanks!

import processing.dxf.*;
import ComputationalGeometry.*;
IsoSurface iso;

boolean record = false;

void setup(){

  size(640,640, P3D);

  iso = new IsoSurface(this, new PVector(0,0,0), new PVector(200,200,200), 15);

  for(int i=0; i<20; i++){
    PVector pt = new PVector( random(100), random(100), random(100) );
    iso.addPoint(pt);
  }
}
void draw(){

    if (record) {
    beginRaw(DXF, "output.dxf");
  }

  camera(150,150,150,50,50,40,0,0,-1);
  lights();
  background(220);

  noFill();
  noStroke();
  iso.plotVoxels();

  fill(255,0,255);
  iso.plot(mouseX/10000.0);

  if (record == true) {
    endRaw();
    record = false;
  }
}

void KeyPressed() {
  if (key == 'R' || key == 'r') {
    record = true;
  }
}

Not sure how this IsoSurface class draws things on screen. The DXF library captures regular Processing calls, nothing else.

Have you tried with a simpler sketch, one of the 3D examples of Processing, to see if pure DXF recording is working for you?

Ah right, thanks for letting me know. I'll try with a simpler sketch to check this out. Do you have any idea how I'd go about exporting the 3D vector information from whatever is generated using the computational geometry library?
