Is it possible to create a controlp5 controlFrame with the P3D/OPENGL Renderer?

Just using size(w, h,P3D); in the ControlFrame example produces a white ControlFrame without anything in it.....Any ideas?

Thanks!

The Controlp5 Controlframe in Processing 2.0 replaces the ControlWindow.
I haven't been able to figure out how to close  the Controlframe window.....

What I want to implement is to open a second frame on button click and then also be able to close this window again.
Trying to just x the frame somehow doesn't work.

Any ideas? Thanks!

Below is the Controlframe example.

Hey Folks,

I downloaded the new 2.0 Beta 4 this morning on my OSX Lion Mac and realized there is a problem with the peasycam library (peasycam v105). The basic Hello Peasy example won't react to any mouse interaction. Any ideas what could cause this?

Hey folks,

I have a question concerning Processingjs with HTML5 Input.

The example variableinputs that comes with 2.0a8 shows many HTML5 GUI Elements working with ProcessingJS. It doesn't show a simple Button however.

I can get a Button to show up by entering the code into the interface below.

1.        this.addButton = function ( l, c ) {
               var input = this.addInputField ( l, "button" );
               input.value = c;
               return input;
           }
   

But I don't get my sketch to listen to the button.  My Controller looks like this:

1.  void setController ( Controller ctlr )
    {
        // labels are supposed to be existing function names
       
         element = ctlr.addButton( "ButtonCallback", true );
        ctlr.setElementLabel( element, "A Button here" );
2. }
   

Any ideas what could work?

I have a question: 

In the Processing 2.0 revisions.txt it reads for 
PROCESSING 2.0a6 
+ Fix whitespace issue with XML http://code.google.com/p/processing/issues/detail?id=975


I know it has been discussed before, but somehow I am still confused and don't 
understand this: If I open the "LoadingXMLObjects" example on Processing 2.08
and add println(xml.getChildCount()); or println(xml.getChildren().length); 
(which is equivalent) I both times get the result "7",
 allthough it should be "3". 
It seems a whitespace is still counted as a child.

Is that a known bug that is not fixable?

Hey folks,

I am trying to run the Contributed library example video>Movie>Speed in P3D (OPENGL) mode.

size(320, 240,P3D);

 I need OPENGL for other parts of a sketch and I am trying to play a .mp4 video file.


While on Processing 2.05alpha I get some mistakes, but the video + sound is running.

Display 0 does not exist, using the default display instead.
 <Error>: CGContextGetCTM: invalid context 0x0
 <Error>: CGContextSetBaseCTM: invalid context 0x0
<Error>: CGContextGetCTM: invalid context 0x0

2012-08-06 07:41:24.091 java[843:2007] invalid drawable
OpenGL error 1282 at bot endDraw(): invalid operation


On Processing 2.08alpha (was the same at 2.07alpha) however, trying to play the .mp4 file, plays back the sound but no image. The error message is:

OpenGL error 1282 at bot endDraw(): invalid operation

The video file in the example "balloon.ogg" works fine. So I tried to transcode the mp4-video file I have to .ogg and other formats, but no dice.

Any ideas, what specifications a video and codec have to have in order to play back in OPENGL mode? Because the interesting thing is that as soon as I switch OPENGL off, the video+sound of the mp4 file play just fine.

Thanks for any ideas!

Hey folks,

I usually run my programs on Mac, but want to export an application that will run both on Mac and Windows. My exported application which runs well on Mac doesnt run on Windows.

I downloaded Processing 2.06alpha for windows and tried to run any OpenGL examples on there and I always get the same mistake, see below. Any ideas? Thanks for your help!

Hey Folks,

much thanks and appreciation for updating to 2.06!

I downloaded the new Processing 2.06alpha for MacOSX and tried to run my programm  which uses the OPENGL   P3D renderer, that works fine with 2.05.
(I tried running it on Lion and Snow Leopard)

I get the following error message:

I have no idea, since I don't even have anything called "online".... any ideas what could cause this?

Thanks in advance!

Hi Folks,

Does anybody know how to get a centroidal Voronoi tessellation (CVT)  out of a Voronoi tesellation generated with either the Voronoi Diagram from the Mesh Library ( http://www.leebyron.com/else/mesh/)     or toxiclibs library.

The algorithm is very simple, but somehow I cannot get hands on the correct solution: Its called Lloyds algorithm and goes like this

• The Voronoi diagram of all the points is computed.
• Each cell of the Voronoi diagram is integrated and the centroid is computed.
• Each point is then moved to the centroid of its voronoi cell.

So basically one just needs to access the myRegions[] array (on the Mesh library) and get the area or better directly the centroid.

Any ideas on how to to that?

The goal would be to iterate the Voronoi tesselation until the distribution of the polygons is almost even (with a certain threshold)
http://en.wikipedia.org/wiki/Lloyd%27s_algorithm

Anybody has ideas or has done something similar? Thanks alot.

Here the Mesh library code to begin with

1. float[][] points = new float[3][2];
   			
   points[0][0] = 120; // first point, x
   points[0][1] = 230; // first point, y
   points[1][0] = 150; // second point, x
   points[1][1] = 105; // second point, y
   points[2][0] = 320; // third point, x
   points[2][1] = 113; // third point, y
   
   Voronoi myVoronoi = new Voronoi( points );

   MPolygon[] myRegions = myVoronoi.getRegions();
   
   for(int i=0; i<myRegions.length; i++)
   {
   	// an array of points
   	float[][] regionCoordinates = myRegions[i].getCoords();
   	
   	fill(255,0,0);
   	myRegions[i].draw(this); // draw this shape
   }

Hi Folks,

again quite the newbie question, but I couldn't figure it out and browsing the web didn't give me an answer.

I understand how to parse special characters (ä ü ö ß etc...) from XML to Processing: instead of ä -I use &#228;. Okay that worked....

but how can I write it to XML with proxml that it converts an ä back to &#228;

Any ideas?

Thanks!

This might be a very stupid question, but when I wanted to start using XML in Processing 2.0 I understand that XMLElement got changed to XML class, but how do I make it work??

I took the old example from XMLElement and tried to adapt it, without luck, what am I missing in the code below?
It gives me a NullPointerException, allthough the XMLfile sites.xml is inside the data folder.
Any ideas? Thanks!

1. // The following short XML file called "sites.xml" is parsed
   // in the code below. It must be in the project's "data" directory
   // <?xml version="1.0"?>
   // <websites>
   //   <site id="0" url="processing.org">Processing</site>
   //   <site id="1" url="mobile.processing.org">Processing Mobile</site>
   // </websites>
   
   XML xml;
   
   void setup() {
     size(200, 200);
    
     xml = loadXML("sites.xml");
     int numSites = xml.getChildCount();
     for (int i = 0; i < numSites; i++) {
       XML kid = xml.getChild(i);
       int id = kid.getInt("id");
       String url = kid.getString("url");
       String site = kid.getContent();
       println(id + " : " + url + " : " + site);   
     }
   }
   

Hi,

I am using the great GSVideo Library to play videos inside my sketch. As I need OpenGL/GLGraphics for other parts of my sketch, I am happy that GSVideo works like that.

Now I would like to integrate a nice UI, like unplayer
however unplayer doesn't seem to work with GLGraphics or could anybody manage to make that work?

Any other idea if there is already libraries out there that have, play, pause, skip, rewind, etc. implemented for GSVideo?

Thanks!

Hi Processing Community,

I am having trouble applying a transparency effect to an OpenGL texture. The below example is the Textured Spere Example from the included OpenGL library with   tint(255,150);   added.

The problem I am experiencing is that allthough I turned lights off (noLights();) I get a sort of shadow on my Sphere, which, only makes half the sphere transparent and the other half not. When I rotate it, I can get the whole sphere transparent or totally non-transparent, depending on where I rotate.

The desired effect would be that the whole sphere is transparent, no matter where I rotate it.

Any ideas would be highly appreciated!

Thanks!

Dear GSVideo community,

thanks to all your posts I managed to export a processing application for Mac and Windows (copying the gstreamer folders accordingly)

Now the Mac Application runs very smoothly, but the Windows application is very shaky and even with a small video very bad.

I used the HDMovie example, and to see the error you can download the applications here:
http://www.klein-bottle-film.com/HDMovie.zip

I also tried the normal Movie example but with the same problem. Any help is much appreciated!

Hi Processing Community,

this is probably a no-brainer to some of you more experienced folks but its driving me crazy.....

I want to use the Root finding algorithms from the Apache Commons Math Library (which is working fine otherwise)....

How do I have to define the function??? The below code doesn't work....Lets say I want to find the zero of cosine, between 1 and 5.....

1. 
   UnivariateRealFunction function =cos();
   
   final double relativeAccuracy = 1.0e-12;
   final double absoluteAccuracy = 1.0e-8;
   
   UnivariateRealSolver solver   = new PegasusSolver(relativeAccuracy, absoluteAccuracy);
   double c = solver.solve(100, function, 1.0, 5.0, AllowedSolutions.LEFT_SIDE);

Hey I have succeeded in exporting an application on Mac that contains a video (with jmcvideo), but it won't work on Windows.

Now I have tried GSVideo and also didn't succeed. I saw some remarks about copying the GStreamer folder and changing the root of the video etc, but nothing seems to work.

Can anybody tell me exactly the steps how to do this, so that a Windows Application including a video runs? All I need is a simple Video Playback.

I run Processing 1.5.1 on Mac which renders with OPENGL or GLConstants.GLGRAPHICS.....hope that helps!

Thanks alot!

P.S. Does anybody know what video changes are gonna come with Processing 2.0? Will this work out of the box eventually?

I just discovered jmcvideo for me. It works fine in my sketches, which I am running on a Mac. Once I want to export it to an application I copy the video files to a "data" folder. The application runs on Mac, but  just shows a blank grey screen on Windows, so doesn't start the application.

Does anybody have any other ideas how to solve this?

Thanks!

Hey Folks,

this might be a total newbie question, but I can't figure it out.

So I am making a calculation in a float that brings me a NaN value (that is because the result of the computation is a complex number... for example sqrt(-1)  ).

How can I convert this float into a complex value.

I used
http://commons.apache.org/math/api-2.0/org/apache/commons/math/complex/Complex.html

but there they only tell you how to create a Complex Number from two values. I only have my float computation....

My ultimate goal is to return just the real-value of my computation (not sqrt(-1), something more complicated....)

Thanks for any help!

I just discovered jmcvideo for me. It works fine in my sketches but once I want to export it to an application, the application just shows a blank grey screen, so doesn't start the application.

I am using Processing on Snow Leopard. Does anybody have an idea, whats the problem? Is it even possible to export jmcvideo to Applications?

Do I maybe have to copy some more files to the application folder? Any help would be highly appreciated!

Hi I am using the controlp5 GUI in the same window as my graphics. With the help of the controlp5 with Peasycam I could figure out how to make the GUI inresponsive to my Peasycam actions.

 Now I want to do the same with perspective().

From what I understand perspective() has nothing to do with peasycam, but does anybody know a similar way to use perspective() (for example change the field of view) only on the graphics part and not on the GUI?

Thanks!

I am fairly new to Processing, so this could be a very simple question:

Peasycam is working great!

When in some settings I enjoy the fact that after rotating a 3D object the object still spins further a bit (depending on how fast you turn), in other settings I would like to disable that. Does anybody know a code, that stops the rotation as soon as I let go of the mouse. Something like camera.velocity=0 or camera.DampedAction.stop()  ?
I tried around, but couldn't achieve what I wanted.

Thanks for any help!
