The next upcoming version does contain Swing and Offscreen rendering support. Swing is solved, while using offscreen rendering. This work effort is sponsored by desys.com - thanxs a lot. --------- XFree4.0 support is coming up. Also all GL/GLU functions are mapped using Mesa 3.3 (XF4.0 version). All functions of GL > 1.1 are loaded dynamical .. --------- I hope I can get the new version online next week monday/tuesday.

I have a Linux machine with a 3dfx Voodoo card. I want to take advantage of Mesa's DRI support in XFree86 4.0, and my card is one of the supported ones. However, it is not clear to me why there are two files in GL4Java: libGL4Java2.3.0.0-Linux-glibc2.1-Mesa31Nvidia-x86.zip libGL4Java2.3.0.0-Linux-glibc2.1-Mesa31Soft-x86.zip What is the difference? Which one should I use? This seems to imply special support for Nvidia, but since GL4Java is layered over the native OpenGL, don't I get hardware rendering if the native OpenGL supports my card? ------------------------------------------------------------- Dennis Doubleday email: dd...@yo... yourfit.com, Inc. web: http://www.yourfit.com/ |

Hi! IMHO current version of gluProject gluProject(..., double[], double[], double[]) is extremely unintuitive and anti-OO.

Hi! Sven, I've discovered: 1. Bug in GLU method gluNurbsProperty(...). According to the specs it takes float value as its third parameter. That's how it's done in GL4Java for now but some properties require boolean values (GL_TRUE and GL_FALSE) which are probably defined as 1 and 0 in C. These properties do not work in Java - there is no method like gluNurbsProperty(int, int, boolean). For example, this line glu.gluNurbsProperty(nurbsRenderer, GLU_AUTO_LOAD_MATRIX, GL_FALSE); is currently invalid. 2. Several constants in GLEnum are named like this: GL_MAP1_VERTEX_3 where they should be GL_MAP1_VERTEX3.

I think so. And/or JDK version. I've tried exactly the same trick a while ago IIRC with Mesa 3.0 and JDK 1.1.6 and it didn't worked. Send me your example code so I can see if it works here... I think about starting section named 'GL4Java usability examples' or similar. What do you think? Would you use it or think other people would? Your font example would fit well into this...

Hello, I've written a small example of how to render Java fonts using the stencil buffer support in the latest version of GL4Java. I'm posting it in the hope that somebody finds it educational or useful. If anybody has any advice on how to render scalable fonts that look better at smaller sizes, I'm all ears (eyes?).

Well - it depends :)
On MS-Windows machines:
MS-IE's JVM is much faster than Netscapes JVM :-(
The resulting speed of MS-IE looks fine for me
(play with the "use repaint" and "sleep" buttons on
e.g. morph3D applet - remind, the default
(using repaint & sleep) is safe for most JVM's ...
but you can play with and customize it for diff. JVM/OS).
Unix:Netscape's JVM is also quiet fast
May be the Java2 PlugIn for Netscape is faster ?!
I tested:
Linux 2.3.99 pre6, XFree86 4.0 DRI (Vodoo3, 16bpp)
gl-demo: gears
native : 75-79 fps
java2 & javacomp (inprise) (no repaint, no sleep -> max-fps): 78 fps
Netscape (no repaint, no sleep -> max-fps): 58 fps
So - the results looks acceptable ? YES !
AND the responsivenes of the native application
(cursor keys to rotate) are not that nice, the java one is !
(Remember that the rotation-speed, is set slower in the java app.
This is not the fps render speed)
It depends on your OpenGL hardware acceleration also, of course.
And - of course - Java IS slower than native code !
Well, all demos we have for GL4Java runs well with hardware
acceleration,
even the GLLandscapeWorld stuff, etc.
Also: The usage of display lists is nearly as fast as the native usage !
Just the data generation/manipulation in java is, of course, slower
than the native counterpart !
But you are right, we should create a fps measurement
- and a kind of performance user guide and performance comparison
between native and all the different java vms (incl. OS).
So we can make a statement what we can expect !
Yours, Sven

Dear GL4Java devloper/user, --------------------- DRI GLX XFREE 4.0 I have had success, running GL4Java under XFree86 4.0 & DRI ! I attach a text file, which describes the bugs and tricks .. I send this info to the DRI developer mailinglist also, so hopefully some bugs in DRI will be fixed soon. GL4Java runs with a Vodoo3 in DRI mode and Indirect mode. Other cards should be tested by others (I bought myself a damn Vodoo3 card, just for this purpose :-( --------------------- NVIDIA GLX XFREE 4.0 The current NVidia GLX module for XFree86 4.0 did not work for me (GeForce256 AGP, Linux 2.2.14, XFree 4.0, glibc2.0) with the sun/blackdown java vm's ! I just get segmentation faults :-( The funny thing is, that it works with the Netscape Java VM :))) I guess it is time to encourage nvidia AGAIN to support the DRI project .. ---------------------- Static GL <= 1.1 / Dynamic GL > 1.1 & EXTensions Request for comments ===================== I want to change the native library linkage for GL4Java, to use fixed symbols (current state) for the OpenGL/GLU functions specified till OpenGL 1.1. All newer functions should be linked dynamic using the new glXGetProcAddressARB function, while the 1st call ! Of course, the Java method stubs must be added all the time, but we can use all libGL.so libraries, which supports GL 1.1 ! (Currently we must add dummy methods for unavaiable native methods) Additionally a kind of "boolean *Exists()" methods will be added for this purpose ... ---------------------- Swing Support Request for comments ===================== Last month, the company DESYS (http://www.desys.com/) contacted me. They want Swing (within Java2) supported by GL4Java ! DESYS does develop a new kind of lightweight gui framework, which is based upon Java and uses Swing. In the near future they want support OpenGL 3D rendering, using GL4Java. Here are my main ideas - in a brainstorm way: Prerequisites: - Usage of Java2 - To use OpenGL in Java, we can not use the native window, which is opened by the JavaVM (under some OS) ! Solutions: 1 - Lightweight component gl4java.swing.GLJPanel ! This component draws itself in a OffScreen mode and acts like e.g. an ImagePanel (copy the native OffScreen Data to a Java Image which can be painted by the JVM therefore)! All GL/Swing components will use OffScreen rendering (may be fast), and the OffScreen content must be offered (copied) to the Java VM (slow) ! 2 - Heavyweight component gl4java.swing.GLHeavyComponent ! This component creates an own native window ! The native window will show up (bring to front), if the component is completly viewable ! - The native window must be connected to the native java root window (->Heavy). - The swing component stack order must be controlled, so the native heavy window can be showed and hided, depending of the visible state of the component. Rendered is done fast ! But the OpenGL rendering is only viewable, if no other component hides the GL component - even partial ! (-> Ugly ! Component can not contain any more components ! ) 3 - Implementing an OpenGL based java.awt.Graphics and java.awt.Graphics2D ! E.g.: java.awt.GLGraphics extends java.awt.Graphics ! Because everything is drawn in one native OpenGL window, we are fast and should run into trouble ! Synchronisation, animation, etc. is fine, because of the homogene rendering toolkit (-> OpenGL). (We cannot use the original JVM native window, because of the restriction described in the prerequisites !) So, my personal favorite is - of course - the universal solution number 3 ! Many ideas can may be found in the Kaffe project ! -------------------------------------------------------------- Comments, ideas & manpower is welcome !

May be we can change the sense of the Java part of GL4Java, meaning - that we do not mean Sun's Java TM, because we mean the iland of Indonesia .. :)) http://www.eastjava.com/ Well, I will add a note to the project name about this confusion :))) But if you all do not want to give indonesia some credits :), we can change the project name - not the package name ! But I really would love this new sense. > Ah! almost forgot :-) URL is: > http://3d.linart.krakow.pl/OfficinaArtificialis/OpenGL/gl4java/logoContest/index.html > Well, we need a logo - true !

Hi! It seems there is no other way than to change name of GL4Java :-(. So, in the name of all GL4Java community I started GL4Java Name And Logo Contest. Please send me your proposals. When we will have several interesting ones, someone will need to make a decision. It's Sven's right to choose whether there will be popular voting or he will decide arbitrary or something else. Anyway, now it's time to send your submissions! Suggestions: - save your images as PNGs, preferably black-and-white or grayscale. If you think color version looks impressive, prepare two: grayscale and color version. - make images small (up to around 200x200 pixels if possible) - make images SMALL (please, do not send me files larger than 20-30 kb) - obey to Sun's and SGI's rules Ah! almost forgot :-) URL is: http://3d.linart.krakow.pl/OfficinaArtificialis/OpenGL/gl4java/logoContest/index.html I have prepared two proposals that are already there.

Dear GL4Java members, I apologize for the delay in responding. It seemed appropriate to allow the group to fully comment. This is the last input we received at our trademarks@sun alias. First and most important, Sun appreciates your ongoing support of the Java technology. Kerry Bonin has pointed out a number of the obligations that trademark law imposes on trademark holders. All trademark holders must protect against improper use of its marks in order to prevent potential confusion in the marketplace about the source or origin of products and services bearing identical or similar marks. Mark Simms asked a number of good questions about trademarks and logos. Because trademark owners must protect against the use of similar marks, Sun's position, set forth in our guidelines at http://www.sun.com/policies/trademarks is that it does not permit companies to adopt company names, product names or service names that incorporate the JAVA element. Sun does not license exceptions to this policy. Our department is not familiar with QT4Java but we will investigate, as we do with all reports of names incorporating the JAVA element, and will take action if appropriate. We also want to clarify that trademark law does not permit "fair use" of logos. While it is possible to make "fair use" of word marks, such as JAVA, to identify the relationship between another product, service or technology and Sun's Java technology, it is not "fair use" to use a logo. If any of you on the alias are aware of any case law to the contrary, please pass it on to tra...@su.... We hope you find the response helpful and we hope many of you are joining Sun for the JavaOne conference.

Hi! I am currently implementing reshaping GLCanvas in my application. It's not the first time I came to conclusion that both AWT and Swing are piece of shit altogether, in my not so humble opinion. They're overloaded with methods and classes lacking real usability in many cases. Do any of you know of any reasonable, feature-rich alternative GUI? Preferably implemented on top of separate (non-AWT) native windowing system? I know there is Biss-AWT but it looks awful and Dog GUI but it's too limited for my needs. It's kind of OT, but I came to this question while writing GL4Java code, so maybe not so OT :-) TIA, Max -- Max Gilead (gi...@li...) http://3d.linart.krakow.pl/OfficinaArtificialis ----------------------------------------------------------------------------- |
