Hi! I want to convert this output to UNIX Time Stamp but unable to find out how... It´s the current system date with zero hours/minutes/seconds. Can someone help me with an example? Would be very appreciated! Best regards!
2. int day = day();
3. int month = month();
4. int year = year();
5. int hour = 0; //hour();
6. int minute = 0; //minute();
7. int second = 0; //second();
9. println(day+"/"+month+"/"+year);
10. println(hour+":"+minute+":"+second);

oauthP5 / Openpaths: How to convert API response to JSONArray?

Hi! I´m a student working on my thesis project, and using openpaths. I'm having a problem when trying to use my data that is returned from the API. On the "blprintOpenPathsExample.pde" example there is an attempt to convert the response.getBody() in to a JSONArray. Wich gives me an error "JSONArray is ambiguos". After looking at the javadocs, I found out that response.getBody() returns a String. So, as a work around, I'm saving dynamically that string as a local "data.json" file and then load it back as a JSONArray. But I would like to convert it directly without having to save a local file. I´m sure its possible... Am I doing something wrong? Can someone help me? Would be very appreciated!
Best regards!
Here is my code:
final String ACCESS = "";

final String SECRET = "";

final String URL = "https://openpaths.cc/api/1";

void openPaths()

{

OAuthService service = new ServiceBuilder()

.provider(OpenPathsApi.class)

.apiKey(ACCESS)

.apiSecret(SECRET)

.build();



OAuthRequest request = new OAuthRequest(Verb.GET, URL);

Token token = new Token("", "");

service.signRequest(token, request);



request.addQuerystringParameter("start_time", String.valueOf(System.currentTimeMillis() / 1000 - 30*24*60*60));

request.addQuerystringParameter("end_time", String.valueOf(System.currentTimeMillis() / 1000));



Response response = request.send();

//println(response.getBody());

String[] receivedJSONBody = { response.getBody() };

//println(receivedJSONBody);

saveStrings("openpaths.json", receivedJSONBody);



JSONArray loadedJSONObjects = loadJSONArray("openpaths.json");



for (int i=0; i<loadedJSONObjects.size(); i++)

{

JSONObject location = loadedJSONObjects.getJSONObject(i);



double longitude = location.getFloat("lon");

double latitude = location.getFloat ("lat");

double altitude = location.getFloat ("alt");

long timeStamp = location.getInt ("t");



println("Longitude: "+longitude);

println("Latitude: "+latitude);

println("Altitude: "+altitude);

println("Time Stamp: "+timeStamp);

println("");

}

PS3Eye & Processing 2.0b8 on osx not working...

My problem is that I want to use a PS3 Eye, as I did in the past, in a mac osx 10.6.8 with Processing 2.0b8.

Before, with Processing 1.5, I used Macam (macam.componente). Now as I understood, Processing as 2.0+ version stopped using Quiktime, but if I am not wrong, macam.componente uses Quiktime... Só now I don´t know how I am going to use my PS3 Eye in my latest project with Processing 2.0b8

Does anybody know how I can use PS3 Eye Camera with Processing 2.0b8?

It´s getting kind of urgente now :(...

Thanks

Hi!

Which is better for Android development? Processing or OF?

Which is lighter weight for the system, which would be less battery consumer...
It is going to be an app that has to be "on" 24/7, in system background...

Between these two frameworks, what are the pros and cons, for android development in particularly

Thanks!

Hi!

I´m working on a sketch where I´m using an Arduino for an interface and want to trigger some sounds with it.

My problem relies on when I trigger the sound before I start the arduino port, in the 'void setup' it works fine, but when I try to trigger the sound after I start the arduino port, like in 'void draw', it won´t make any sound.

Is there any incompatibility when using these two libraries together?

Thanks!

breakShape() with pattern shape

Hi,

I´m using breakShape to draw a rectangle that has a circular hole in the middle, and It works just fine!

My problem is when I want that rectangle to have a pattern instead of a fill(color).

If somebody could help me with this... maybe there is a work around I´m not seeing...

My goal is to save an image.png that has a square pattern with a transparente hole in the middle.

The code that I´m putting here put me in a dead end, because breakShape only works with JAVA2D, and textures don´t work with JAVA2D.

Need help....

int r = 65;

int a = 15;

PGraphics pg, pg2;

void setup() {

size(200, 200, P2D);

pg = createGraphics(width, height, P2D);

pg2 = createGraphics(width, height, JAVA2D);

}

void draw() {



pg.beginDraw();

pg.smooth();

pg.noStroke();

for (int i=0; i<=width; i+=6) {



pg.beginShape();

pg.fill(175, 0, 0);

pg.vertex(i, 0);

pg.vertex(i+1, 0);

pg.vertex(i+1, height);

pg.vertex(i, height);

pg.vertex(i, 0);

pg.endShape(CLOSE);



pg.beginShape();

pg.fill(255, 0, 0);

pg.vertex(i+1, 0);

pg.vertex(i+6, 0);

pg.vertex(i+6, height);

pg.vertex(i+1, height);

pg.vertex(i+1, 0);

pg.endShape(CLOSE);

}

pg.endDraw();



pg2.beginDraw();

pg2.smooth();

pg2.noStroke();

pg2.noFill();

pg2.textureMode(NORMALIZED);

pg2.beginShape();

pg2.texture(pg);

pg2.vertex(0, 0, 0, 0);

pg2.vertex(width, 0, 1, 0);

pg2.vertex(width, height, 1, 1);

pg2.vertex(0, height, 0, 1);

pg2.vertex(0, 0, 0, 0);

pg2.breakShape();

pg2.vertex(width/2, r);

pg2.bezierVertex(r+a, r, r, r+a, r, height/2);

pg2.bezierVertex(r, (height-r)-a, r+a, (height-r), width/2, height-r);

pg2.bezierVertex((width-r)-a, (height-r), (width-r), (height-r)-a, width-r, height/2);

pg2.bezierVertex((width-r), r+a, (width-r)-a, r, width/2, r);

pg2.vertex(width/2, r);

pg2.endShape(CLOSE);

pg2.endDraw();





image(pg2, 0, 0, width, height);

}

void mousePressed() {

pg2.save("data/circleHole.png");

}

Thanks!

nyARToolkit - when I flip videocapture (mirror effect) the overlayed objects don´t "flip"

[0 Replies]

Hi!, I am using nyARToolkit.
When I flip videocapture from my webcam doing the mirror effect, the overlayed objects don´t "flip" they go opposite way, where they original went before flipping. I know that this happen because I am feeding the library function the instance from the webcam and not the fliped frame. The problem is when try to feed the function the fliped frame he doesn´t recognize the marker.

Please help, it´s for a school project.

Thanks for your time.

Here is my code:

import processing.video.*;

import jp.nyatla.nyar4psg.*;

import processing.opengl.*;

Capture webcam;

SingleARTKMarker realidade_aumentada;

Cubo cubo1;

void setup() {



  try {

   quicktime.QTSession.open();

  }

  catch (quicktime.QTException qte) {

   qte.printStackTrace();

  }



  size(640, 480, OPENGL);



  String[] devices = Capture.list();

  //println(devices);

  webcam = new Capture(this, width, height, devices[4], 30);

  //webcam.settings();



  realidade_aumentada = new SingleARTKMarker (this, width, height, "camera_para.dat", SingleARTKMarker.CS_LEFT);

  //println (realidade_aumentada.VERSION);

  String[] marker= { "patt.volcom" };

  realidade_aumentada.setARCodes (marker, 80);

  realidade_aumentada.setConfidenceThreshold (0.6, 0.5);



  cubo1 = new Cubo(20);

}

void draw() {



  if (webcam.available()) {



   colorMode(RGB, 255, 255, 255, 100);



   PImage frame = new PImage(webcam.width, webcam.height, RGB);



   webcam.read();

   webcam.loadPixels();



   for (int x=0; x<webcam.width; x++) {

   for (int y=0; y<webcam.height; y++) {

   int loc = (webcam.width- x- 1) + y*webcam.width;

   frame.pixels[x+y*width] = color(red(webcam.pixels[loc]), green(webcam.pixels[loc]), blue(webcam.pixels[loc]));

   }

   }



   frame.updatePixels();



   hint (DISABLE_DEPTH_TEST);

   image(frame, 0, 0);

   hint (ENABLE_DEPTH_TEST);





   switch (realidade_aumentada.detect(webcam)) { // with frame he doesn´t recognize the marker



   case SingleARTKMarker.ST_NOMARKER:

   break;



   case SingleARTKMarker.ST_NEWMARKER:

   println("Apareceu o Maracador");

   break;



   case SingleARTKMarker.ST_UPDATEMARKER:

   PGraphicsOpenGL pgl = (PGraphicsOpenGL) g;

   realidade_aumentada.beginTransform (pgl);



   pushMatrix();

   translate (0, 0, 20);

   cubo1.desenha();

   popMatrix();



   realidade_aumentada.endTransform();

   break;



   case SingleARTKMarker.ST_REMOVEMARKER:

   println("Desapareceu o Maracador");

   break;

   }



  }

}

class Cubo {



  private float tamanho = 0.0;

  private color cor = color (0);



  Cubo (float tamanhoexterior) {

   tamanho = tamanhoexterior;

   cor = color ( random(0, 255), random(0, 255), random(0, 255) );

  }



  void desenha () {

   noStroke ();

   fill (cor);

   box(tamanho);

  }



}

Hi!

With the Processing QRCode Library from Daniel Shiffman, can i use a custom image like a Logotype instead of a QR code?
If not can anybody indicate such a library.

Any help would be great.

How to install libJMyron.jnilib compiled for intel macs

Hi,

I´m trying to make JMyron library work on my Intel Mac 10.6.5.

I found out that I needed to download an compiled version of libJMyron.jnilib for intel macs.

But it comes in a .zip extension.

When I try do decompress the file it tells me it´s an app.

What should I do to replace this file in the JMyron library?

Thanks!
