Export dxf from animation

Hey-o. I have an animation of triangles that change size based on mouseX and mouseY inputs. I'd like to export the geometry created as a dxf file. I know you can do this for a pdf because you can pause and resume what's "recorded" to the pdf explained here: http://processing.org/reference/libraries/pdf/index.html under "Pause while recording". Is this possible for a dxf? If not, how can I set up this animation to export the geometry at some point? Right now I have it set up to use a key press. Any help would be greatly appreciated! Keep on rockin in the free world.

import processing.dxf.*;
float xoff = 0.0;
float x,y, xspeed, yspeed, angA;
//boolean recording;
//PGraphicsPDF pdf;
boolean record;
void setup() {
size(1000,500,P3D);
background(255);
// pdf = (PGraphicsPDF) createGraphics(width, height, PDF, "triangles.pdf");
//cam = new PeasyCam(this,100);
}
void draw() {
if (record) {
beginRaw(DXF, "output.dxf");
}
noiseDetail(3,0.57);
x += 5;
xoff = xoff + .01;
float n = noise(xoff) * width;
pushMatrix();
stroke(0);
//noFill();
//fill(255*cos(n),45);
//if (n*1.5 >= 180) {
// fill(15);
// } else {
// fill(255);
// }
translate(x-(n/5),y+(n/5),.05);
rotate(radians(n/1.5)+(y-x/10)/10);
//rotate(radians(n*1.4)+(x-y/10));
rectMode(CENTER);
fill(255);
stroke(0);
//rect(0,0,mouseX/4,mouseY/2);
triangle(0,0,50, 0, mouseY/4,mouseX/2);
fill(0);
stroke(255);
//rect(0,0,mouseY/4,mouseX/2);
triangle(mouseX/2,mouseY/4,50, 0, 0,50);
fill(mouseY*mouseX/275, mouseX/(mouseY+1));
stroke(0);
//rect(0,15,mouseY/2,mouseX/4);
triangle(0,0,mouseX/3, mouseY/2, 0,50);
//box(60,30,3);
popMatrix();
//line(n, 0, n, height);
if (x >= width+100) {
x = 0;
y+= 15;
}
if (y>= 300) {
y = 0;
//saveFrame("sizeNoise####.jpg");
//background(255);
}
if (record) {
endRaw();
record = false;
}
}
void keyPressed() {
if (key == 'r') {
record = true;
}
if (key == ' ') {
saveFrame("frame####.jpg");
}
}

" how can I set up this animation to export the geometry at some point?"
By using a conditional statement...
if (someConditionIsOK) record = true;

PhiLho - thanks for the response. I believe I have the conditional statement on line 76. The problem is that it's not working!

I also should reiterate that all I need is the geometry, NOT the animation stuff such as key frames or motion paths.

Well, your code works, in the sense it saves a .dxf file when I hit the r key.
Now, the caveat is that it works only in Processing 1.5.1, not in 2.0b5...

Aahh ok. I downloaded version 1.5.1 and, yes, it worked. However, it only records the geometry in that specific frame, which is just a few triangles. How would I get it to record all the geometry from the previous frames as well?

Thanks for your input once again, PhiLho.

I got it to work using the code below. It's all about getting the recording to start and then end at different frames.

import processing.dxf.*;
float xoff = 0.0;
float x,y, xspeed, yspeed, angA;
//boolean recording;
//PGraphicsPDF pdf;
boolean record;
void setup() {
size(1000,500,P3D);
background(255);
// pdf = (PGraphicsPDF) createGraphics(width, height, PDF, "triangles.pdf");
//cam = new PeasyCam(this,100);
}
void draw() {
// if (record) {
// beginRaw(DXF, "output.dxf");
// }
noiseDetail(3,0.57);
x += 5;
xoff = xoff + .01;
float n = noise(xoff) * width;
pushMatrix();
stroke(0);
translate(x-(n/5),y+(n/5),.05);
rotate(radians(n/1.5)+(y-x/10)/10);
//rotate(radians(n*1.4)+(x-y/10));
rectMode(CENTER);
fill(255);
stroke(0);
//rect(0,0,mouseX/4,mouseY/2);
triangle(0,0,50, 0, mouseY/4,mouseX/2);
fill(0);
stroke(255);
//rect(0,0,mouseY/4,mouseX/2);
triangle(mouseX/2,mouseY/4,50, 0, 0,50);
fill(mouseY*mouseX/275, mouseX/(mouseY+1));
stroke(0);
//rect(0,15,mouseY/2,mouseX/4);
triangle(0,0,mouseX/3, mouseY/2, 0,50);
//box(60,30,3);
popMatrix();
//line(n, 0, n, height);
if (x >= width+100) {
x = 0;
y+= 15;
}
if (y>= 300) {
y = 0;
//saveFrame("sizeNoise####.jpg");
//background(255);
}
//if (record) {
// endRaw();
// record = false;
// }
}
void keyPressed() {
if (key == 'r') {
if (record) {
endRaw();
println("Recording stopped.");
record = false;
} else {
beginRaw(DXF, "output.dxf");
println("Recording started.");
record = true;
}
} else if (key == 'q') {
if (record) {
endRaw();
}
exit();
}
}
