Well we'd need 1.4 support for sure.
About gl4java updates, I personally have access to the gl4java sourcefore
CVS so I may update some code for you. But I guess Sven could register you
as a gl4java developer if you ask him.

I'd be very interested to integrate an OpenAL binding into OpenMind if it i=
s
LGPL. I'd like to review yours if you are ok.

Alban

I'm sorry, what I meant to ask was how to load a png and use it as a 
texture in gl4java.  The gl4java png texture loader doesn't support 
inputstreams.  Just file names or URLs..

Apologies for the poorly worded request ;-)

Peter.

RE: [gl4java-usergroup] loading pngs from jar files

[Byron W. <bsl...@mi...>]

put the png in a jar file then do something like 

URL url = YourClass.class.getResource("your.png"); 

Image img=Toolkit.getDefaultToolkit().getImage(url); 


So if your class is called "Game"

URL url = Game.class.getResources("your.png"); 

rememeber that the string you pass to the getResources method is the
path in the jar file to the image so

getResources("/your.png") would point to the root of the jar file. 

There is another method that might be helpful:

InputStream in = Game.class.getResourceAsStream("your.png"); 

Then you can do whatever you want with the inputstream.

[gl4java-usergroup] Re: Is GL4Java dead ?

[Alban Cousini <aco...@mi...>]

From what I know, gl4java maps the complete OpenGL 1.4 API and is very
stable. Everytime I thought I had found a bug, I ended figuring out I was
wrong and the gl4java API was good. So actually, we can say gl4java is quit=
e
up to date.

But we have all noticed Sven was much less present on the mailing list for
the past few monthes, and he is not here to answer our concern that the
gl4java API might not evolve anymore towards OpenGL 2.0. Sven certainly has
his own personal reasons for being less present, and he has done so much
great work on gl4java during 7 years none of us would dare to judge his lac=
k
of presence.

Since I have spent nine monthes of full time programming on the OpenMind
engine using gl4java, and since OpenMind is the technology I intend to use
for the future game developments of my company, I personnaly feel very
concerned about how the future of the API. But maintaining the OpenMind ope=
n
source project already eats an impressive amount of time on my schedule and
I know I wouldn't be able to help maintain gl4java as well, though I'd be
interested to.

I think it'd be good that someone who has skills in java, c++ an JNI would
be promoted as a secondary project admin aside with Sven, and could bring a
new life to the gl4java API and help animate the community.

There are a few issues that I think should be adressed on gl4java actually =
:

- Set up a compilation script that can easily be run on a cross platform
basis. As some of you may have noticed from the numerous messages on the
mailing list, the make script of gl4java is not easily portable, and many
people have hard time compiling gl4java on Windows and MacOSX. On OpenMind,
one of our open source developers -Robert Cadenas- has setup a compilation
script for apache ANT. ANT is a "make like" tool coded in java and targeted
to cross platform compilation. Compiling OpenMind has never been so easy an=
d
it works perfectly on Windows, MacOSX and Linux. Creating such an ANT scrip=
t
for gl4java would make it more accessible to new open source developers.

- Ensure CG compatibility and provide some demo featuring vertex and
fragment shader code

- I would personnaly get rid of Java 1.1, 1.2 and MS JVM compatibility in
order to simplify the code, the compilation process, and drive people to us=
e
java 1.4

- Eventually make a lifting to the web site, and animate the community.

I am personnaly commited to use gl4java with the OpenMind scene graph, and
I'd sincerely like to continue working with it. If I succeed selling my
video game project using OpenMind I could eventually have some employee hel=
p
developping the gl4java API, but if I don't have this chance and the API
should die slowly, I may have no other choice than moving the scene graph o=
n
some other binding that gets a more dynamic support.

I wish someone would have the time and the interest to bring gl4java back t=
o
a more dynamic development.

[gl4java-usergroup] Re: Mac OS X Issue

[Alban Cousini <aco...@wa...>]

Hi Mark,

I am facing the same issue while porting OpenMind on MacOSX. On my machine,
I get this error only in fullscreen mode. Since no sample provided with the
MacOSX release of gl4java uses fullscreen mode, I beleive the compatibility
for fullscreen mode has not been implemented, but we should ask Gerard
Ziemsky what he knows about this issue. Running your program in a regular
window should work fine.

Another issue I have been facing was an "invalid drawable" error. It occurs
when you try to create a GLAnimCanvas inside a Jframe. There is an
incompatibility. Thus if you want to use swing, create a regular awt Frame,
and add your GLAnimCanvas to it. You can always add swing UI components to
this frame, but the Window component must not be a Jframe.

I'd be interested to know if you found a workaround for this error as I am
myself interested into MacOSX.

Gerard Ziemsky told me he was no longer expecting to support the MacOSX por=
t
of gl4java because the implementation has become too complicate. Apparently=
,
the Java 1.4.1 implementation has been done by someaone named Dmitry
Markman.=20
Sven Gothel has been giving very few signs of life lately and is answering
less and less my emails since a few monthes. I'm getting pretty worried
about the future of gl4java in general and it's MacOSX implementation in
particular. I hope the API is not going to die slowly... If someone has som=
e
more optimistic news, I'd be interested to ear these.

Alban Cousini=E9

[gl4java-usergroup] Suddenly running really slow above a certain poly count

[SHL <shl...@ya...>]

My application (using Java with gl4java) tends to run
smoothly up to a point, but when I increase my polygon
count by even a little bit above a certain threshold
it all of a sudden becomes *unresponsive to input* and
runs *really slow*. 

The weird thing is if I compile the most poly
intensive object into a display list and call the
display list everything is really smooth again.
Supposedly display lists are supposed to be faster,
but I do not think the display list *alone* caused
that much of a sudden performance increase. 

The strange thing is that if I up the polygon by even
a little bit above a certain threshold it *suddenly*
becomes unresponsive and slow. 

I guess I could just use the display list, but I fear
that there is some underlying problem that I have
missed. 

What could be causing this and how do I fix it? Maybe
it is a java/gl4java specific issue?

Here is some code that we use for tessellating polygons. I'm not 100% =

we did it correctly, but it does seem to work OK. When I have more than =
one
GL4Java display in the same application, I'll sometimes get a native =
error
outside the JVM related to the tesselation callbacks. But I don't know =
if
I'm doing something wrong, or it is a library bug. (BTW, the 'Triplet' =
class

[gl4java-usergroup] Help Request

[Alex A. <a.a...@ol...>]

Hi Agili Kais,

I downloaded the Tennis app.

I use the following line to start the code (jre instead of jdk) to make =
it work fine.

> c:\[path to my jdk]\jre\bin\java -cp . Game

Note: I don't use any preset path.

Setting Infos:

I use to put GL4Java Java Libraries into the JDK directory structure=20
(I don't want to mess with Windows or other OSs):

> c:\[path to my jdk]\jre\lib\ext\gl4java-glffonts.jar
> c:\[path to my jdk]\jre\lib\ext\gl4java-glutfonts.jar
> c:\[path to my jdk]\jre\lib\ext\gl4java.jar
> c:\[path to my jdk]\jre\lib\ext\png.jar

Note: the ext dir is the standard dir for jdk extensions library, it =
seem more clean to put extra jars here...=20
and most of all: java finds them always.
If you redistribute your software with embedded JRE you will find this =
way very useful.

And finally I use to put GL4Java OS related libraries (DLLs in this =
case) into:

> c:\[path to my jdk]\jre\bin\GL4JavaGljMSJDirect.dll
> c:\[path to my jdk]\jre\bin\GL4JavaJauGljJNI.dll  =20
> c:\[path to my jdk]\jre\bin\GL4JavaJauGljJNI12.dll=20
> c:\[path to my jdk]\jre\bin\GL4JavaJauGljJNI13.dll=20
> c:\[path to my jdk]\jre\bin\GL4JavaJauGljJNI14.dll=20

It works for all my projects in JDK1.3 & JDK1.4.

Sorry 4 my english... I'm Italian, so I invite everyone to write in =
english (or pseudo like me) into this newsletter.

[gl4java-usergroup] RE : gljDestroy failed (free)

[<aco...@mi...>]

Hi,

We were having the problem with OpenMind. I think this comes from the
fact the GLContext is already managed by gl4java in class GLAnimCanvas
and GLCanvas, and though GLContext management appears in almost every
gl4java example, managing it results in this error, because you make a
new call to these methods while they have just been called by -say- the
GLAnimCanvas.display() method, and while the context hasn't been
released yet, you are trying to make it current again.

I don't have a very good understanding of glContext management and
multithreading but this how I have solved this problem with OpenMind,
after having tested various combinations of code :

public void init(GLDrawable drawable)
{
	glj.gljMakeCurrent();  =20
              =20
        // init code goes here    =20
       =20
	glj.gljFree();
      firstRun=3Dtrue;
               =20
}


public void display(GLDrawable drawable)
{
        if(firstRun){
        	glj.gljMakeCurrent();
                firstRun=3Dfalse;
        }
=09
	// display code goes here
=09
	// notice there is no gljFree() here and gljMakeCurrent()=20
	// is only called at the first run   =20
               =20
}


public void cleanup()
{
	// making context current prevents VM crash in nvogl.dll=20
	// for Nvidia cards when calling glDeleteTextures
       glj.gljMakeCurrent();=20

       // your cleanup code goes here

       glj.gljFree();
}


public void reshape(int width, int height)
{
	glj.gljMakeCurrent();
=09
	// your reshape code goes here
       =20
	glj.gljFree();
}

This structure for the main loop fixes the gljDestroy failed (free)
error message, and VM crash on cleanup when using NVidia cards.

Regards,

Alban

Objet=A0: [gl4java-usergroup] gljDestroy failed (free)

I get the error 'gljDestroy failed (free)' everytime I try to close my
application.

I've searched for this error on google but I haven't seen any good
answer yet. What do I need to do to get it to work?


My display function looks like this:

public void display()
{
   glj.gljMakeCurrent();
     =20
   ...
   ...
   ...

   glj.gljSwap();
   glj.gljFree();
}

I read in GL4Java's documentation that you should call gljfree before
gljDestroy so I've overridden doCleanup like this:

public void doCleanup()
{
   glj.gljFree(true);
   super.doCleanup();
}

But that didn't help.


Hope someone can help me.

You should ask your questions in english, if you want some good answer
(newsgroup's masters speak english)..
Ici tout le monde parle anglais, si tu veux des r=E9ponses tu devrais =

For your error you should try with the JDK1.4 and check your version of

Re: [gl4java-usergroup] Packing GL4Java with a program

[Antony R. <ri...@to...>]

Having had no success all day, I decided to try and use something previously
unknown to me - batch files.

Batch files are quite scary - in terms of their simplicity and power.  I
came up with the following batch code that would run my sample java class
passing various system properties using the syntax specified by Pepijn.

... and it seems to work on all my home computers!!  I'll have to wait until
tomorrow to test on works systems, but don't see there being a problem at
all.

A quick google search for "creating batch files" should provide you with an
abundance of information on how batch classes work (which was my main
problem).

I found this site to be quite good:
http://home.att.net/~gobruen/progs/dos_batch/dos_batch.html

Find below my sample batch code (setting the "java.ext.dirs" property in
this example):

@echo on

rem
rem Determine if JAVA_HOME is set and if so then use it
rem
if not "%JAVA_HOME%"=="" goto found_java

set RIBOTSIM_JAVACMD=java
goto file_locate

:found_java
set RIBOTSIM_JAVACMD=%JAVA_HOME%\bin\java

:file_locate
rem %~dp0 is name of current script under NT
set RIBOTSIM_HOME=%~dp0

rem : operator works similar to make : operator
set RIBOTSIM_HOME=%RIBOTSIM_HOME:\bin\=%

rem attempting to run the main java command, passing in system properties
"%RIBOTSIM_JAVACMD%" -cp e:\ "-Djava.ext.dirs=%RIBOTSIM_HOME%\libs" GLTest
%1 %2 %3 %4 %5 %6 %7 %8 %9

:end

What do you mean by this registry key? As far as I know gl4java does
not access the windows registry. What I meant by specifying the system
property is this:
java -Djava.library.path=<some path> YourApplication
This setup works fine for me on every machine I've tested on. The only
limitation is that you can't do this when you are running your
application as an applet or via webstart. (Both are possible but
require some more effort)
