Hello everybody i have a question about AR technology!
Exactly with the ARToolKit framework which i have problem. I did everything what is in the tutorial but the application cannot recognize the symbol what i have putted in.
tutorial page: link
what i have create: - pattern file about symbol (filename.patt) and added this to the project under \Data\ - with the mk_patt.exe recognized the image what i would like to be as the source. - modified the source:
markerID = ARToolKit.getInstance().addMarker("single;Data/patt.eslogo;80");
But i don't know what i have to do more. By the way this is an example and with the original source the program working and drawing the cube on the symbol. and the new pattern file is the same style so that is not problem.
Any idea? I did not find useful video what's included the exact method
more detailed:
first of all, after when i used the mk_patt.exe and i given the 'camera_para.dat' of the project, created and added the 'patt.slogo' pattern file, i modified this line, to:
markerID = ARToolKit.getInstance().addMarker("single;Data/patt.slogo;80");
here is the point of the drawing method :
public void draw(GL10 gl) {
...
if (ARToolKit.getInstance().queryMarkerVisible(markerID)) {
cube.draw(GL10 gl);
by the way this is the public 'kosiara' example from git: link
The point of the logcat is this:

I tried with another pattern file and it's working, but the process when i was created the pattern about a symbol was the same like now, and i don't know why the program can't recognize the symbol what i used with the same logic.
Conclusion: Eventually the program working with another symbol what i created with wider line than before and that is the point.
