The question I have is that in the following code I am only changing 1 box every second or so, but i am having to redraw all 8000 blocks each draw cycle. Is there a way to have draw only redraw the changed objects? Is there any way to write these boxes to a single shape or similar and once I update the single box every few seconds, then I update the stores shape, or do I have to redraw everything every 1/60 second..... Any suggestions on improving any areas of this code are appreciated.

Hello guys,

Sorry but I will try to ask something complicated again ... (laughs) ...

Below are two code snippets in the first example has a "silhouette" human, designed with bezier, the example I took in OpenProcessing.

Then there is another code, which like to do something similar, ie have the outline of the human body, but only in 3D, with proscene library could to facilitate rotacionamento, I got an example here in the forum.

Someone would know where I FIND tips on how to facilitate to mount coordinated the human body? (Build the mesh ...) to make these contours in 3D?

If anyone can help me with any tips, I thank the attention.

Thank you very much

I am trying to analyze the amplitude of multiple audio files using the Sound library, but it seems I am only able to analyze one at a time. For example, assuming all three audio files are different, the following code prints the same value for all three analyze() methods:

  import processing.sound.*;

       SoundFile sis;
       SoundFile boom;
       SoundFile bah;

       Amplitude rms_sis;
       Amplitude rms_boom;
       Amplitude rms_bah;

       public void setup() {
          size(640,480);

          sis = new SoundFile(this, "sis.wav");
          boom = new SoundFile(this, "boom.wav");
          bah = new SoundFile(this, "bah.wav");

          sis.play();
          boom.play();
          bah.play();

          rms_sis = new Amplitude(this);
          rms_sis.input(sis);
          rms_boom = new Amplitude(this);
          rms_boom.input(boom);
          rms_bah = new Amplitude(this);
          rms_bah.input(bah);
      }

      public void draw() {
          println(rms_sis.analyze(), rms_boom.analyze(), rms_bah.analyze());
      }

What should I do differently to get all three amplitude values?

Hello everyone! One year ago I composed an algorithm which basically was triggered by a twitter hashtag. the same sketch doesn't work today and I can't understand why. The error it give back is "indexOutOfBoundException: index:0 size:0" on the "Status status = tweets.get(currentTweet);" I tried to compose a new code which kind works only with some "searchString" for others would unlogically (to me) give back the same error. any suggestion?

Hello guys,

I'm trying to combine the use of toxilibs and proscene libraries to view objects in a scene.

How could I set the initial positions of the object? (More to the middle of the screen, and a certain angle - straight for example).

I'm trying to combine more than one command, but it looks like a interfefe on the other, one could give any tips?

Below is the code and the image, to pass a better idea I'm trying to do.

Ok! So for an assignment I need to layer two videos on top of each other. The idea is that the two videos are the same and that one will begin playing before the other to create a sort of "ghost" effect. I've gotten pretty much everything including loading both of the videos as well as putting in the filter, what I can't seem to figure out though is how to get the second video to delay. Any help that can be given is greatly appreciated.

Hi!

I would like to create an array of textfields, just like this:

GTextField [] textfields = {textfield3,textfield2,... etc};

Yet this procedure is always giving me an array of nulls. How to do it properly?

Hi guys,

I have a problem trying to use any of the code from the library of Video Export that they get the same error. Even with the code from the website itself here > http://funprogramming.org/VideoExport-for-Processing/#examples , I also get error with permission thing. say: java.io.IOException: Cannot run program "/Users/Tuang/Desktop/DMA_WORKS/Work1_Facial Muscles/Cam_Rec/sketch_161027a/sketch_161027a.pde": error=13, Permission denied at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048) at com.hamoid.VideoExport.startFfmpeg(Unknown Source) at com.hamoid.VideoExport.initialize(Unknown Source) at com.hamoid.VideoExport.saveFrame(Unknown Source) at sketch_161027b.draw(sketch_161027b.java:51) at processing.core.PApplet.handleDraw(PApplet.java:2412) at processing.awt.PSurfaceAWT$12.callDraw(PSurfaceAWT.java:1540) at processing.core.PSurfaceNone$AnimationThread.run(PSurfaceNone.java:316) Caused by: java.io.IOException: error=13, Permission denied at java.lang.UNIXProcess.forkAndExec(Native Method) at java.lang.UNIXProcess.(UNIXProcess.java:247) at java.lang.ProcessImpl.start(ProcessImpl.java:134) at java.lang.ProcessBuilder.start(ProcessBuilder.java:1029) ... 7 more VideoExport error: Ffmpeg failed.

For more information, read revisions.txt and Help → Troubleshooting.

So I google

1) how to change permission -> which I found that my Mac cannot find the file it said there is no such file.

2) how to find a file in Mac with terminal -> later I found that it is about the space bar in a folder name, so I changed it.

Then, I was able to find a file and I guess I've already changed the permission with chmod 777, since I typed it in and has no error with finding the file thing. However, back to the Processing the same error still there.

3) Do I have FFmpeg ->Terminal said, it cann't find it so I download two versions and installed one but didn't work so try installed another, still didn't work.

Now.. I don't know what to do. Please help! The error still here.

I've been trying to get a sketch running with the Google spreadsheet API for the past couple of days. Found a couple of great articles that really helped but have hit one slightly killer roadblock, writing to the spreadsheet.

I can read in about 20 different ways but whichever command/technique/method I try and use to send information i get an exception. Has anyone tried to do this sort of stuff recently?

A few sites/links that sorted me out this far...

https://developers.google.com/google-apps/spreadsheets/ - Google's home for the API

http://makezine.com/2010/12/10/save-sensor-data-to-google-spreadsh/ - couldn't get the writing part of this to work but could reuse the setup to read

http://blog.blprnt.com/blog/blprnt/open-science-h1n1-processing-and-the-google-spreadsheet-api - Blog article about data collection, works like a charm but doesn't include write functions. Added the code below to the end of SpreadsheetManager class

    void setCellValue(int col, int row, String data) {

    URL cellFeedUrl = worksheetEntry.getCellFeedUrl();

    try{
    CellFeed cellFeed = myService.getFeed(cellFeedUrl, CellFeed.class);
    CellEntry input = new CellEntry(col,row,data);
    println(input.getCell().getRow());
    input.changeInputValueLocal(data);
    println(cellFeed);
    input.update();
    //OR
    //myService.insert(cellFeedUrl, input);
    }catch(Exception e){
     println("Data couldn't be added");
    }
    };

I'm using the library NETWORK to get data from a board esp8266 with httpclient example. But the Processing takes this data once and then run into the following error "Client got end-of-stream." Someone has been there and knows how to solve?

Hi guys, first post so i hope its in the right place. I am working on a project with 30 strips of leds controlled by 4 fadecandy boards. i have everything working and can play "video" very low res across my grid. the question is, can i add a video capture board and send the incoming video directly to my pixel map? in effect processing would just be converting video to pixel map.

any help is greatly appreciated

Regards

Matthew Tiley

I haven't seen anyone implement this function successfully anywhere. New to Processing so the developers API implementation explanation doesn't help much. Looking for an example. Thanks.

Hello.

Some time ago I am trying to create and destroy objects of classes and modify some of its parameters via OSC messages. I tried it with ArrayLists with controlEvents GUI and it works, but there is no way with OSC.

I made this supermegasimple code if someone wants to implement a solution inside:

import oscP5.*;
import netP5.*;

OscP5 oscP5;
NetAddress myRemoteLocation;

circle obj1;

void setup()
{
  size(800,600);
  oscP5 = new OscP5(this,12000);
}

void draw()
{
  background(0);
}

void oscEvent(final OscMessage theOscMessage) {
    if(theOscMessage.checkAddrPattern("/circle")==true) {
     if(theOscMessage.checkTypetag("i")) {
       // /circle name create a circle with this name
       // /circle name erase destroy this circle
     }
    }
}

class circle {
  circle(){}
  void display(){
    ellipse(10,10,50,50);
  }
}

Thanks!

Hi there,

for the art project Global Sounds (http://www.picaroon.eu/work.html ) I would need 7 separated audio outputs, so that every pyramid has one speaker and plays one instrument (=one mp3). I was wondering if I could use the minim library together with an audio interface somehow? Any ideas/suggestions?

Thank you very much in advance!! Rebecca

Hey guys,

I need to some help...

I would like to send audio from Max to Processing (using Minim) by SoundFlower.

I need to use 4 in/out but i can set only the device and not the single outputs and inputs. Is there any possibility to set each in and out?

Thank you so much

I am new to processing, and made a knitting program as my first processing project.

I want to use a slider to adjust the brightness and saturation of the image but can't work it out.

I have tried to look for the answer and tried lots of things on my own but can't find a way! The sliders have been added using cp5 GUI, and I want to use the sliders to adjust the brightness.

I looked here: https://processing.org/tutorials/pixels/ here: https://processing.org/reference/colorMode_.html here: https://processing.org/examples/brightness.html

and tried to add this somehow but to no avail!

any help appreciated (and remember I am a total beginner so please forgive the clunky code :) ) thank you! Becca

Hi all. First post here so please be gentle :-)

Been trying to get a drop down menu to work, based on the example below, the menu displays and responds fine but i can't figure out how to read what 've actually selected. The "controlEvent" doesn't appear to respond as I click on menu items. Tried processing 2 and 3 and updated my controlP5 library.

Can anyone offer any help? Thanks.

import controlP5.*;
ControlP5 cp5; // you always need the main class
 int b = 0 ;
void setup() {
  size(300, 300);
  cp5 = new ControlP5(this);

  // add a dropdownlist at position (100,100)
  DropdownList droplist = cp5.addDropdownList("mySuperList").setPosition(100, 100);

  // add items to the dropdownlist
  for (int i=0; i<5; i++) {
    droplist.addItem("myItem " + i, i);
  }
}

void draw() {
  background(0);
  // controlp5 autodraw is on by default (if you use the default JAVA2D renderer)
  // this means the gui is automatically drawn at the end
}

// controlEvent monitors clicks on the gui
void controlEvent(ControlEvent theEvent) {
  if (theEvent.isGroup()) {
    println(theEvent.getGroup() + " => " + theEvent.getGroup().getValue());   // *** this isn't responding ***
  }
}

Hi all

I prototyped an a/v project using sample playback in stereo and now comes the time to spatialise the sound (3 channels, possibly concurrent playback). I thought this would be a bread-and-butter exercise but it seems either I'm missing something or it's not off the shelf?!

I'm running Processing 3 on OS X 10.10.5

I've reviewed Minim & Beads and not found an obvious example. I read this forum post where the solution seemed to be to run multiple stereo sound cards!

I've hacked around based upon this Minim example but I can't get any audio device to tell me it has more Lines available (Audio 8 DJ, Soundflower)

Line.Info allLines [] = mixer.getTargetLineInfo(); println(mixer.getMixerInfo()); println("MSP allLines: "+allLines.length);

I started poking around in Java Sound directly based on this SO post and this gist but same deal, although I have verified I have a "Direct Audio Device" Mixer.

Minim states "Using setOutputMixer you can also create AudioOutputs that send sound to specific output channels of a sound card." but that method is deprecated and I can't figure out how to use it regardless!

I've read the Java Sound docs but can't see anything obvious telling me one way or the other if this is possible.

So..

Anyone out there running multichannel audio (from a single sound card) via Processing (or plain Java)? If so, please tell me what I'm missing!

Cheers
