Just something I knocked together in a few hours last night, as encouragement for the development of OpenGL in applets.

I just wanted to see how man ypolygons I coudl get on ascreen at once all moving together etc, and the answer appears to be "quite a few"

There is a little work needed, but no where near as much as previously. I think you'll have to wait for 0111 to come out first though as I had to use my slightly altered version.

Basicly you export as normal, edit the HTML file a little, then upload it with certain jar files. No need to set up a keystore and sign things anymore.

Well, I've never used any external Java thing to build stuff so you may hav to translate this for your situation.

Basicly, I did the sketch as normal (with OpenGL) then exported to an applet.

Edit the HTML file so it resembles:
Code:

<applet code="com.sun.opengl.util.JOGLAppletLauncher" 
archive="jogl.jar,MySketch.jar"
width="800" height="600" mayscript="true">
<param name="image" value="loading.gif">
<param name="boxmessage" value="Loading Processing software...">
<param name="boxbgcolor" value="#FFFFFF">
<PARAM NAME="progressbar" value="true">
<param name="subapplet.classname" VALUE="MySketch">
<param name="subapplet.displayname" VALUE="Random OpenGL thing">
</applet> 

Then get the jsr-231 beta 03 jogl.jar and jogl-natives-*.jar files from https://jogl.dev.java.net/servlets/ProjectDocumentList?folderID=4843&expandFolde
r=4843&folderID=0
And put them in the same directory as the HTML/MySketch.jar file on your server, and it'll just work.

This is all dependant on a slight change to processing-0110 though, but which will be fixed with 0111 I believe.
0111 may also come with the beta 03 versions of the jogl jar files so you don't need to go get them yourself.

If you can't wait for 0111 the change to make to the processing source is very simple, and is documented at http://dev.processing.org/bugs/show_bug.cgi?id=309

hello all,

Was the export applet that uses OPENGL implemented in 111 in the end?

When I attempt to export a sketch that uses OPENGL either as an applet or as an application neither will run at all. My sketch runs fine (if very slow) as an applet in a browser using the normal processing renderer but I just get a blank white stage when I try to run it in abrowser when exported using OPENGL?

cheers,

james

that's a huge help JohnG! many thanks!

Fantastic!

I'm having trouble though getting my applet to work on-line (following your tutorial at http://www.processinghacks.com/hacks/opengl_applet ; thanks by the way for making it).  It seems those 4 files need to be placed within /com/sun/opengl/util and not within the root directory of the applet (easily changed by modifying the html that accompanies the applet I guess).  And I had to download files from https://jogl.dev.java.net/servlets/ProjectDocumentList?folderID=4843& ;exp (the link you provided above), to get hold of a .class file that the java console was saying did not exist (i'm using Processing version 0113).  

Fingers crossed I'm doing something wrong!  I still can't get my opengl applet to work (p3d works fine) so hopefully my steps above are stopping things working.  Any ideas?  

Cheers, Andy.

Thanks! Didn't see that bit of text at the top of the hack.

My opengl applet didn't work at first, and after much scrolling of code, scratching of head and loud swearing I found that for some reason my applet only works when I specify the screen size using numbers, and not using variables specified elsewhere.  Eg.

 size(800,600, OPENGL); works
 size(xdimension,ydimension, OPENGL); does not work

I think I encountered this problem once before.  It may have been when I was using P3D.

Anyway, not really such a big problem!  Thanks you guys for all your great work you've done for Processing.

sometimes i get hickups with GL applets too. i figured it's due to either skype / IM or my apache running on the same machine. a restart and quitting everything unneeded seems to fix the problem ... anyone an idea how to track what exactly is causing the problem

(os-x 10.4 | safari / firefox)

best,
