simple ARToolkit
Nov 18th, 2008, 9:24am  
I am trying the simpleARToolkit by Bryan Chung:

http://www.bryanchung.net/?p=227

And i have everything work very good. Except it has problem of "out of memory" with the highlighted code "ar01.showImage()".

I have checked the source of the library and found that it is using the Capture class of the video library. Pixel by pixel display.

My code is here:
http://www.the-demos.com/artoolkits_try1.zip
which is super sample by just show the camera image. It has the error "out of memory" after running around 1 minute. Does anyone come across this problem as well? And do anyone know the solution? I am using 0135, 0142 and 0156 and got the same error.

import processing.video.*;
import processing.opengl.*;
import saito.objloader.*;
import javax.media.opengl.*;
PGraphicsOpenGL pgl;
GL gl;

import pARToolKit.*;
SimpleARToolKit ar01;



void setup()
{
 size(320, 240, OPENGL);
 //hint(ENABLE_OPENGL_2X_SMOOTH);
 hint(DISABLE_DEPTH_TEST);
 frameRate(24);
 pgl = (PGraphicsOpenGL) g;
 gl = pgl.gl;

 //ARToolKit=====================================================
 ar01 = new SimpleARToolKit(this,"patt.sample1");
}

void draw()
{
 pgl.beginGL();
 background(255);
 ar01.showImage();


   pgl.endGL();
 gl.glFlush();

}

I'm using OS X and I have trouble just running the examples. It says the video capture library is missing.
Code:
Exception in thread "Animation Thread" java.lang.NoClassDefFoundError: processing/video/Capture
	at demo01.setup(demo01.java:30)
	at processing.core.PApplet.handleDraw(PApplet.java:1383)
	at processing.core.PApplet.run(PApplet.java:1311)
	at java.lang.Thread.run(Thread.java:613)

I looked at the library's source code and there's an include function that says Code:
import net.sourceforge.jartoolkit.core.JARToolKit;
so I wondered if I needed to install the actual toolkit. Now I can't figure out how to install the Xcode library... Part of the reason I was attracted to processing in the first place. I hate irony.


Anyhow... A little help? By the end of today I'd like to say I've gotten the kinks out so others wont feel my pain.

It is based on jartoolkit which doesn't seem to support Mac OS Sad

I am having grief running this too. I keep getting an error message  - The package "pARToolKit" does not exist. You might be missing a library.

I have created a libraries dir in the sketchbook. I just can't get it to run. On vista here.

I had to add the following import to get the demo01 script to work:

Code:

import processing.video.*;


I hope that this helps.
