GL4Java hasn't been actively developed for a while. I'd suggest you look at JOGL, which provides much of the same functionality and is being more actively developed.

Hi i tryed to instal gl4java for Mac OS X Java 1.4.1 Update 1 from the site of Mr Ziemski. The problem is i cannot run it, because the insteller ask me to get a certificate on http://www.jausoft.com/Files/Java/1.1.X/GL4Java/Installer/ This "new" certificale is from 11.12 2001 and expires on 1.3 2002 and the instalation fail ( message : applet non installé ) How it is possible and what can i do ? Thanks for answering, and also for developping nices programs. Bertrand Bratschi physicist Geneva |

Any help would be greatly > appreciated. Thanks. JDK 1.4 changed how the native window handle is represented in the Sun-internal code and the older reflective techniques now no longer work. It is necessary to use the JAWT for portability. Regardless, it shouldn't be necessary to fetch the underlying window handle as there isn't a lot you can usefully do with it, at least from Java. You may want to check out JOGL, http://jogl.dev.java.net/ , which has some newer functionality than GL4Java exposes and also happens to have all of its internals written in Java for easier tinkering. -Ken |

Hi,
I've been trying for a while to use the X11HandleAccess class to retrieve
the window handle, but haven't been able to get it to work. The error I'm
receiving is:
java.lang.NoClassDefFoundError: sun/awt/DrawingSurface
at
gl4java.jau.awt.motif.X11HandleAccess.achieveData(X11HandleAccess.java:40)
at
gl4java.jau.awt.motif.X11HandleAccess.getWinHandle(X11HandleAccess.java:73)
at TJRemote.TJRemote$MainCanvas.update(TJRemote.java:65)
at sun.awt.RepaintArea.paint(RepaintArea.java:169)
[...]
I'm new to OpenGL in Java, so there may be something I'm just doing wrong,
but here's the code, it's pretty straightforward:
class TJRemote {
static Frame f;
public static void main(String[] args) {
f = new Frame( "TJRemote" );
f.add("Center", new MainCanvas(500, 500));
f.setLocation(500,30);
f.setLayout(new BorderLayout());
f.setSize( 500, 500 );
f.show();
}
static class MainCanvas extends GLCanvas {
public MainCanvas(int w, int h) {
super(w,h);
}
public void update(Graphics g) {
GLContext glc = getGLContext();
if (glc == null) {
System.out.println("Null Context");
return;
}
X11HandleAccess x11 = new X11HandleAccess();
long drawable = x11.getWinHandle( (this), g);
System.out.println("drawable: " + drawable);
}
}
}
I'm using Sun's Java version 1.4.2 on Redhat 9. Any help would be greatly
appreciated. Thanks.

Hi, I wrote a small 3d engine over gl4java about a year. I went back to it and I'm having some troubles. I now upgraded my computer from a 1ghz / Geforce2mx up to a 2.4ghz / Radeon9700... And now my performance down right sucks. Am I doing anything wrong? I'm calling setUseRepaint(false) <but still calling repaint method on the GLAnimCanvas> I have setUseFpsSleep(false) and setUseYield(false)... I'm assuming that there is one setting that I just can't use on the Radeon that is causing most of the troubles. Many of the demos are also slower. Trouble is I want to use it with an OLDER ATI card (an Radeon7000 that works with an arcade monitor) Any suggestions (other then get out my old Geforce2mx card : ) Thanks! |

Scott, Make sure that the Java component to which you're trying to add hardware surface is a Component.

I'm at my wits end... been trying all day to get a pared-down version of my app running as sample code for JFree-D. I've tried everything, I swear, but I still keep getting: gl4javaAttach: CGLSetSurface failed gl4javaResize: CGLUpdateContext failed Of course, I never get that in the full application. Stepping through, the first error seems to come from native code. Can anyone translate those errors for me, or otherwise help me past this roadblock?

I created a project on SourceForge for "jFreeD2", to facilitate sharing and collaboration with anyone interested: http://sourceforge.net/projects/jfreed2/ This is my somewhat improved version of Gerard Ziemski's snapshot of JFree-D, a minimal Java3d implementation over gl4java. The anonymous CVS access lags 24 hours or so behind, so you can't see the source that way yet... should turn on by tomorrow (Wednesday) evening.

A much easier way (in my opinion) to accomplish something like this it to run your application as a Java Web Start application. You just have to make sure all your jar files are signed with a certificate (you can either buy one or make one). http://java.sun.com/products/javawebstart/ Go there for more info. --- Dan Kulp <dw...@rc...> wrote: > Hi, > I was wondering... if I have an applet on a > web page does everybody that comes to the > webpage need to have gl4java installed on their > machine?

Hi, I was wondering... if I have an applet on a web page does everybody that comes to the webpage need to have gl4java installed on their machine? Or can I just package the gl4java classes with my applet as a jar? What is the minimum requirement on the users end? Does the user need java2? ... basically I really want to use gl4java, but I need it to be compatable "out of the box" with as many browsers as possible...how can I package it so that it maximizes the number of browsers it will work with? thanks... |

I use sun jdk and Netscape 7.1 in Windows 98. I have dowload the gl4java installer, and install it correctly. When I try to execute a gl4java demo, it says Execption in thread "main" java.lang.NoClassDefFoundError: gl4java/awt/GLCanvas But if I use microsoft jvm and Internet Explorer all it's ok. If I use Internet Explorer and sun jvm I get the same exception: Execption in thread "main" java.lang.NoClassDefFoundError: gl4java/awt/GLCanvas Anyone know because I can't use Netscape and sun jvm to execute gl4java in Windows 98??? In Windows 2000 and Windows XP all works ok, I can use sun jvm and Netscape. I use sun jdk 1.4.1_01. I can't use the online installation for Netscape, it gives me an error. java.lang.SecurityException: cannot verify signature block file META-INF/ZIGBERT at sun.security.util.SignatureFileVerifier.process(Unknown Source) at java.util.jar.JarVerifier.processEntry(Unknown Source) at java.util.jar.JarVerifier.update(Unknown Source) at java.util.jar.JarFile.initializeVerifier(Unknown Source) at java.util.jar.JarFile.getInputStream(Unknown Source) at sun.plugin.cache.CachedJarLoader.authenticate(Unknown Source) at sun.plugin.cache.CachedJarLoader.access$600(Unknown Source) at sun.plugin.cache.CachedJarLoader$5.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.plugin.cache.Cache.privileged(Unknown Source) at sun.plugin.cache.CachedJarLoader.download(Unknown Source) at sun.plugin.cache.CachedJarLoader.load(Unknown Source) at sun.plugin.cache.JarCache.get(Unknown Source) at sun.plugin.net.protocol.jar.CachedJarURLConnection.connect(Unknown Source) at sun.plugin.net.protocol.jar.CachedJarURLConnection.getJarFile(Unknown Source) at sun.misc.URLClassPath$JarLoader.getJarFile(Unknown Source) at sun.misc.URLClassPath$JarLoader.<init>(Unknown Source) at sun.misc.URLClassPath$3.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at sun.misc.URLClassPath.getLoader(Unknown Source) at sun.misc.URLClassPath.getLoader(Unknown Source) at sun.misc.URLClassPath.getResource(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at sun.applet.AppletClassLoader.findClass(Unknown Source) at sun.plugin.security.PluginClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.applet.AppletClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.applet.AppletClassLoader.loadCode(Unknown Source) at sun.applet.AppletPanel.createApplet(Unknown Source) at sun.plugin.AppletViewer.createApplet(Unknown Source) at sun.applet.AppletPanel.runLoader(Unknown Source) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source) |

Hi Sven, I'm one of the two co-authors of Jogl (Chris Kline is the other) and the initiator of the project. We began developing Jogl because we wanted to use the latest OpenGL 1.4 features and extending and maintaining GL4Java had become too difficult due to the large amounts of legacy code and native code. (You'll remember I was an active developer of GL4Java for over a year and contributed its JAWT, New I/O and GLDrawable/GLEventListener support.) Jogl is a completely new source base. There is no code relationship between it and any other OpenGL binding for Java, GL4Java included. Concepts have been borrowed liberally from, in particular, GL4Java and Magician, but all of the code is new. Major architectural differences between Jogl and GL4Java include: - Jogl is written almost completely in Java. There are about 50 lines of handwritten C code in the entire project. This was made possible with a new tool called GlueGen, a glue code generator with some of the same properties as GL4Java's C2J but which is powerful enough to generate Java-level accessors for concepts like C structs and function pointers. We bound the low-level JAWT, WGL and GLX routines into Java first and then built the OpenGL context implementations on top of them. Having all of the low-level APIs exposed to Java (though not necessarily to the end user) makes it much easier to extend the framework. - The notion of the OpenGL context has been removed from the public API. This is an important change because it makes the implementation more robust and makes it easier to perform certain kinds of optimizations. It also hides a lot of unnecessary complexity from the end user and makes it easier to extend the framework; pbuffer support was added to Jogl with very few public API changes. - GLCanvas and GLJPanel are now final classes. The only way to interact with OpenGL is now through the GLEventListener interface. This change eliminates the primary source of errors I have seen reported over the past couple of years on the GL4Java mailing list, namely subclassing e.g. GLCanvas and forgetting to perform some of the context manipulation the superclass had been doing. (Note that some Jogl users have provided good reasons why these classes should be subclassable, so this may change, but all of the methods related to OpenGL context management will remain final.) - Animation support has been factored out into an Animator class, so there are no longer GLAnimCanvas and GLAnimJPanel classes. - Jogl includes Magician's notion of a composable pipeline, in particular the DebugGL concept. This makes debugging OpenGL applications much easier and in fact I think it makes OpenGL applications written in Java easier to debug than the same application written in C. Jogl (which includes GlueGen) is open source under the BSD license. It can be checked out via cvs; instructions are at http://jogl.dev.java.net/ . It may be necessary to sign up as an Observer of the project; I'm not sure whether the guest cvs accounts are working. Currently the development team (i.e. the number of people who have commit access to the repository) is small and I think we'll probably be keeping that number small. However, I'm personally very open to accepting new developers, at least once all of the processes around this have been figured out; currently I'm not involved with this planning. I think we'll have a code review process so there can be some validation of changes going in to the source base. I hope you and the other GL4Java developers will join the Jogl project instead of starting a new one. Jogl was designed to be a clean and minimal, yet full-featured, system and I think we've achieved those goals. I think it's a good base to extend and to build on top of. There are some fairly advanced Jogl demos, many ported from NVidia's sources, at http://jogl-demos.dev.java.net/ ; check them out from the CVS repository or grab the demo binaries from the Files section of http://jogl.dev.java.net/ . We showed these and other demos in a talk at this year's JavaOne conference; slides for technical session 2125, "Advanced OpenGL for the Java Platform", can be found linked off of http://servlet.java.sun.com/javaone/sf2003/conf/sessions/48-all-regular.en.jsp . -Ken |

Discovered the answer to my problem a few minutes after posting... Isn't that always the way ;-) If anyone's interested - my problem was not calling ByteBuffer.order(ByteOrder.nativeOrder()) on my direct byte buffers prior to converting them to float buffers. I should have recognised the potential byte ordering problem the first time round, but there you go ;-) Peter. |

Does anyone have a jogl glVertexPointer / glDrawElements example I could have a look at? I have coded these in C++ but can't get them going in Java/Jogl. I suspect that I might have done something wrong with the use of buffers.... Can anyone help? Cheers, Peter. |
