create an application with openGL?
Apr 29^th, 2005, 1:16am

Hi

I need some help;

I need to create pc and mac applications from openGL processing sketches;

there are lots of threads on creating application in the alpha forum;

questions:

1) will an application with openGL work?
2) can someone kindly point me to the best method for creating both apps? I remembering following a set of instructions last year and failing miserably. So, any forum thread link is welcome.

i just tried it using a similar method, it would appear that it only works in "present" mode (which is perhaps better anyway?) but i got the following to work:

1) i used the "CustomLetter" example, and added the following piece of code to the end of it:

static public void main(String args[]) {
PApplet.main(new String[] { "--present", "--display=1", "CustomLetter" });
}

this will initiate the sketch in present mode, using the first display (p5 now has multi-display support, tho incomplete). for another sketch, change "CustomLetter" to whatever your sketch is named

2) from the command line, i went to the applet folder and started it with:
java -cp CustomLetter.jar CustomLetter
and it started up fine.

so you could put this into a .bat file so that it'd be double-clickable. on the mac you can make a similar file that's titled "something.command" which is essentially a double-clickable shell script. there's also the stuff about putting the class name into a MANIFEST file and all that, which should still work.

the holdup on export-to-application is that it's easy to implement but hell to test.. i'm a little wary of putting it in there without having time to test it a lot, for fear of mutiny here on the board, but who knows.

ok; what can be wrong:

name of my sketch: gl_time

1) added to the code
Code:


static public void main(String args[]) {
  PApplet.main(new String[] { "--present", "--display=1", "gl_time" });
}

2) command line, at the right folder:

java -cp gl_time.jar gl_time

and I get:

Usage: PApplet <appletname>
For additional options, see the javadoc for PApplet

...and nothing happens

any ideas?

thanks!

lunetta Junior Member Offline Posts: 77	Re: create an application with openGL? Reply #5 - May 7^th, 2005, 7:38pm update: after a windows restart, it worked. (damn windows logic). by the way, it worked great on both windows and mac. My only advice is to add a keypressed with if (key=='q') { System.exit(0); } otherwise the app won't quit and the process will have to be killed

There is also something funny going on with
this approach. Specifically, I took my .jar
file (created via exporting after adding the
appropriate source lines mentioned above) and
then tried to execute it "java -cp X.jar X".
After some trial and error I noticed that this
works ONLY when jogl.dll is in the same directory.
Try, for example, copying the .jar to another
directory (away from the "applet" one), and you'll
get an error. You end up having to copy the jogl.dll
file. I also had to copy a texture map image file
that was needed even though this file is located
in the .jar.

try http://www.cise.ufl.edu/~fishwick/proc/test.zip

download it anywhere and do java -cp Borg3.jar Borg3
to get it to work. Then try removing either the image
file or the jogl.dll file, and try again.

Webstart application.

method 1: should work as long as the server stays up

http://sand.cise.ufl.edu:35380/jsp-examples/processing/Borg4.jsp

method 2: You should right click, save target, and you may
need to rename the file to Borg4.jnlp since for
some reason IE changes the file name to .xml
(java web start is assumed to be installed):

http://www.cise.ufl.edu/~fishwick/proc/Borg4.jnlp

PRESS "q" to quit the full screen operation

i get this while running "java -cp Borg3.jar Borg3" in linux:
Error while running applet.
java.lang.RuntimeException: Before using OpenGL, you must first select Import Library > opengl from the Sketch menu.
at processing.core.PApplet.size(PApplet.java:757)
at Borg3.setup(Borg3.java:31)
at processing.core.PApplet.display(PApplet.java:1017)
at processing.core.PGraphics.requestDisplay(PGraphics.java:362)
at processing.core.PApplet.run(PApplet.java:921)
at java.lang.Thread.run(Thread.java:534)

i figured it was because i run linux and it was looking for jogl.dll no jogl.so so i moved that into the current directory but no dice. anyone got ideas?

Try this:

1) Download http://www.cise.ufl.edu/~fishwick/proc/Borg3Test.zip
2) Install into your Processing sketch area
3) Ensure that it runs within the Processing IDE
4) Export to create the applet directory
5) Copy the HEAT_STRESSED.JPG texture map from the
data subdirectory to the applet directory. For
some reason, this is necessary even though it is
in the Borg3.jar file.
6) Try java -cp Borg3.jar Borg3 from the applet
directory

Omitting the "--present" from the PApplet.main call and running through "java -cp" will do just that, but the size of the window I get is wrong. Thanks, Michele

I see.

From looking at the code in the CVS, it seems that the applet should work correctly in windowed mode by just omitting the --present (and perhaps --display) arguments. I see code that would presumably resize the applet window when size() is called from Processing.

But maybe things aren't working right, yet. And Ben seemed to imply that he was still working on this.
