The NV_vertex_array_range extension in particular poses a problem because there is currently no fast way to access the region of memory returned from wglAllocateMemoryNV from Java. One must either copy a Java array into it in native code (adding a memcpy to the workload, which has a significant performance impact) or make a native method call per datum read to or written from that region of memory, which is not workable. It turns out that JDK 1.4 will have primitives in the New I/O APIs (JSR 51, on http://java.sun.com/aboutJava/communityprocess/search.html ) which, in conjunction with compiler support, allow one to describe in a completely safe fashion these kinds of memory regions. These primitives can be repurposed to support applications like high-performance graphics. -Ken _____________________________________________________________________________ Kenneth B.

I had some problems porting some code to GL4Java. Specifically, in order to get animation working at all and with good performance, it was necessary to subclass GLAnimCanvas and use the following settings: setUseRepaint(true); setUseFpsSleep(false); setSuspended(false); I found that calling sDisplay() in my main thread reliably crashed the machine (apparently doing something relating to multithreaded access to the OpenGL context the GeForce didn't like). I should note that I played a little bit with the non-free Magician binding and believe that there are some unresolved issues with GL4Java's interaction with the window system. Specifically, a friend and I did an experimental project in which we shoehorned some of GL4Java's sources into the Magician APIs. Unfortunately, it wasn't stable (crashed frequently on his machine), likely due to my inexperience with the multithreading issues in interacting properly with the AWT. However, performance of this system appeared to be significantly better than my first attempts with GL4Java, probably because we were able to avoid the repaint() mechanism and associated thread synchronization. I'm planning on doing some more work on this over the next few weekends -- if anybody has experiences to share or would like to collaborate please send mail. -Ken _____________________________________________________________________________ Kenneth B.

well, I just have added a bugfix for the GLU Callback code
into the CVS repository.
I have announced this to the gl4java-developer mailinglist.
This bugfix will appear in version 2.5.1 !

e.g. (tessdemo.java line 337):
glu.gluTessCallback ( tobj, GLU_TESS_VERTEX, gl,
"glVertex2fv", "([F)V",
2, 0, 0, 0, 0);
The signature "([F)V" is the original java style signature of the
argument-list, your callback method takes (here: glVertex2fv) !
Read SUN's Java Documentation for Java-Callback methods:
http://java.sun.com/docs/books/tutorial/native1.1/implementing/method.html
Here you can find the mapping of function arguments to its corresponding
string signature representation !
>
> What is the meaning of the 5 parameters: voidArrayLen1, voidArrayLen2,
> voidArrayLen3,
> voidArrayLen4, voidArrayLen5, and what value do I need to put ?
>
The maximum number of arrays within the argumentlist of GLU Callback
functions is 5 !
So, the arguments voidArrayLen[1-5] stands for the expected
size of the arrays, which are passed into and from the callback funtion.
E.g. (tessdemo.java):
glu.gluTessCallback ( tobj, GLU_TESS_COMBINE, this,
"combine_callback", "([D[D[F[F)V",
2, 0, 0, 2, 0);
public void combine_callback( double coords[/*3*/],
double vertex_data[/*4xn(=0)*/],
float weight[/*4*/], float[/*m(=2)*/] data )
{
data[0] = (float) coords[0];
data[1] = (float) coords[1];
}
You can see, we do use the arrays data and coords with a size of 2 !
You are not allowed to use nonsense sizes, because this can hurt your
application with a segementation fault !
(Well the GL4Java Callback function checks
the array sizes to OpenGL's maximum, .. but be kind of ..)
The OpenGL machine calls GL4Java's callback function,
which dispatches the call (incl. data) to your java callback function !

Well - just have a look at gl4java.awt.GLAnimCanvas ;-), this is an implementation of an animated canvas .. - fps / sleep calculation - window events - back/front buffer swaping .. > And what's different GLFuncJauJNI and GLFuncJauJNInf ? As you can see, there exist many java classes with the extension nf ! There are native libraries with this extension avaiable either .. nf stands for not final ! The release java classes and native libraries uses the "final" modifier for the native function prototype, so a virtual table lookup is not necessary - -> improves speed ! > I wish your help. > Thanx > sorry for being late yours, sven > ===================== > Brian Youngseog Lee > S/W Engineer > Development 3 > GOMID > ===================== > > _______________________________________________ > gl4java-usergroup mailing list > gl4...@li... > http://lists.sourceforge.net/lists/listinfo/gl4java-usergroup - -- mailto:sgo...@ja... www : http://www.jausoft.com ; pgp: http://www.jausoft.com/gpg/ voice : +49-521-2399440, +49-170-2115963; fax: +49-521-2399442 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.4 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE6giSuHdOA30NoFAARAj3sAKDC/kuBw4HgZsScoC/LaxRTGxIWIACgwgWE QP8v0kWayiqnmaI4E2DyiGQ= =LB2e -----END PGP SIGNATURE----- |

You don't need them to do that. Check http://xmage.sourceforge.net go to project page -> CVS -> file xmage/gl/GLViewport.java - it's working example of such canvas.

Hi there :) I want to write my own animated canvas. Of cause it will be inherited from gl4java.awt.GLCanvas. That's all I know about animated canvas. And what's different GLFuncJauJNI and GLFuncJauJNInf ? I wish your help. Thanx ===================== Brian Youngseog Lee S/W Engineer Development 3 GOMID ===================== |

Hello! I wonder if it's just me or some of you folks also experience this kind of problems. When I write code that deals with GL4Java and Mesa the whole thing is TERRIBLY unstable. Yesterday I tried to implement lighting in my library. All compiled fine and crashed violently when tried to do ANYTHING lighting-related (glEnable(GL_LIGHTING) for example). GL4Java examples didn't worked too. It was with GL4Java 2.4 and Mesa 3.2. Then I decided to upgrade to GL4J 2.5 and Mesa 3.3. Now instead of crashing when I try to enable lighting it now reports LOTS of errors when generating texture object numbers (glGenTextures()). YES! glGenTextures doesn't work!!! So I tried to switch back to Mesa 3.2 while still using GL4J 2.5... so it started to crash while working with textures... another Mesa 3.2 was obsolete for GL4J 2.5... Okay, I figured out that is't Mesa 3.3 which is fucking everything. I tried Mesa 3.2 but it doesn't work with GL4J 2.5. I finally found that unofficial Mesa 3.4 from RedHat RawHide server works OK... but it's some craziness... Sorry for complaining so much but I'm more than angry because of those continuous Java/OpenGL problems... Any opinions? Better solutions? How do you manage to distribute your applications to users? Do they have to use specific versions of libraries? What if user doesn't want to / can't upgrade Mesa? Okay, enough, bye! Max -- ----------------------------------------------- Max Gilead gi...@li...

I've learned to put
if (cvsIsInit()==false || glj.gljMakeCurrent() == false) {
return;
}
before doing any gl4Java drawing, but I don't understand what
these calls do. Something to do with threads?

Hello, Im trying to find a random bug on tesselation=2E I read the GLUFunc documentation but I still have questions=2E I also read the 3 demos (which runs well) of the GL4 package=2E What is the meaning of parameter signature ? If my callback method name is myVertexCallBack (for a GLU_TESS_VERTEX callback), what is the value of the signature parameter ? What is the meaning of the 5 parameters: voidArrayLen1, voidArrayLen2, voidArrayLen3, voidArrayLen4, voidArrayLen5, and what value do I need to put ? Thanxs=2E -- -------------------------------------- Jean-Yves BRUD POLYQUARK - Ing=E9nierie & Cr=E9ation Palahou - 31330 LARRA France Tel: 05=2E62=2E79=2E03=2E33 Fax: 03=2E38 Mail: jybrud@polyquark=2Ecom -------------------------------------- |
