Dear subscribers, I'm happy to announce the release of OpenSG 1.6.0. We added many new features and bug fixes. For a more detailed description see http://www.opensg.org/downloads/CHANGELOG This is the last 1.x feature release. We will add bug fixes to the 1.6 line and perhaps release a 1.6.1. Our main focus lays already on the 2.0.0 release. We are going to release the first beta by the end of this year. Some highlights of the 1.6.0 release are: - CGFX 1.3 support. - MultipassMaterial - Small Geometry data formats (UInt8,UInt16) - BalancedMultiWindow: load balancing cluster - Color and distortion calibration (cluster only right now) - completely new Text implementation. - new even faster tri stripper. Some highlights of the upcoming 2.0.0 release are: - removed begin/endEditCP's - completely rewritten Geometry with vertex buffer objects support. - reduced memory consumption. - frame buffer objects support. - completely rewritten render action.

Dear subscribers, I'm happy to announce the release of OpenSG 1.4. A long time in the making, but the result is really promising. The main part of the work was adding many new features (for a more detailed description see http://sourceforge.net/forum/forum.php?forum_id=424700) and making it even more stable and faster. We also added a completely new StarterGuide (~190 pages) with many new example programs. Some highlights of the new release are: - Shader support (CG and OpenGL Shading Language) - Local light sources - Improved render speed - New fast and extendable binary format (osb) - Volume rendering. - Trimmed NURBS surface node. - Cluster improvements Visit http://www.opensg.org for information and download instructions.

Dear subscribers, the OpenSG Plus project, which supported a number of researchers over the last three years to extend OpenSG in different interesting directions, is coming to an end. To close the project we are organizing a workshop, where all the partners will come together to talk about and demonstrate their results. This event will be held in Darmstadt, in the Fraunhofer IGD building, on December 12th. The program is available on the web at http://www.opensg.org/OpenSGPLUS/abschluss.html. If you're in or around Germany and wish to attend, please drop me a mail at in...@op... with your name and the number of people coming. Attendance is free. Thanks and hope to see many of you in Darmstadt Dirk Reiners -- -- Dirk Reiners OpenSG Forum di...@op... -- The OpenSG Open Source Scenegraph: http://www.opensg.org -- Announcements: http://lists.sf.net/lists/listinfo/opensg-announce |

Dear Readers, just like the last years we will have an OpenSG Birds of a Feather session at SIGGRAPH: OpenSG BOF Tuesday, 29 July 7 - 7:45 pm San Diego Convention Center Room 24A We will finish a little sooner than advertised, to give everybody (us included) a chance to get to the OpenGL BOF in time. If you have an interesting application using OpenSG I would be delighted to present it at the event (or if you're there, you can do it yourself :).I'd also be interested in pictures of applications done using OpenSG, the Gallery page is always open for new shots. Please send anything to me and to Gerrit (vo...@ig...). If you can't make it to the BOF you can try to leave a message for me and/or meet me at the Iowa State University booth (2045). I will be there regularly during the show, I just don't have a schedule yet.

Dear subscribers, this week we successfully organized the OpenSG 2003 Symposium. In an atmosphere characterized by discussions and interactions between presenters and audience we experienced a number of interesting talks, with a significant part covering topics related to OpenSG. The program is available online at http://www.opensg.org/OpenSG2003/program.EN.html, where you can also find a link to the proceedings, which are made available in the Eurographics Digital Library. We hope you enjoy the papers and maybe we'll see you too next year for OpenSG 2004. :) Yours Dirk Reiners --=20 -- -- Dirk Reiners OpenSG Forum di...@op...=20 -- The OpenSG Open Source Scenegraph: http://www.opensg.org -- Announcements: http://lists.sf.net/lists/listinfo/opensg-announce |

Dear subscribers, I'm happy to announce the release of OpenSG 1.2. A long time in the making, it took us quite a while to get here. The main part of the work was restructuring, restyling and documenting the source code, which turned out to be a bigger task than we expected. Did we really write all the code? ;) Apparently yes, and now it is documented, too. I can't say the documentation is finished, but it should be a lot more usable than it was. The Starter Guide has been integrated into the doxygen documentation, which allows you to link from the interface to the structural description and back. We also added some more Tutorials and a commented example showing how to add new types to FieldContainers and how to add new FieldContainers. To also give you some new features we added new Chunks for Vertex and FragmentPrograms (using the ARB_vertex_program and ARB_fragment_program extensions). It's just the first step into the realm of programmable graphics, but it's the beginning of a long and interesting road we're plannung to travel.

Dear Readers,
the call for papers for OpenSG 2003 has been closed, the review is in
full swing and we're eagerly looking forward which to of the wide
variety of interesting papers will be selected for presentation.
Our co-sponsor IEEE has finished setting up the registration website,
and registration is now open at
http://www.opensg.org/OpenSG2003/registration.EN.html. A preliminary
program has been posted on the website, to help you plan your itinerary.
There will be a separate tutorial on OpenSG, which will introduce you to
the concepts and components of the system and lead you to writing your
own OpenSG-based programs in the practical part of the course, which
will be assisted by experienced OpenSG users and developers.
Early registration ends March 17th, so don't miss the opportunity to
make a good deal on the early registration bargains. We encourage you to

Eurographics ACM SIGGRAPH
3D graphics hardware is becoming ubiquitous, and more and more
applications depend on being able to efficiently use the exisiting
capabilities. Low-level interfaces like OpenGL, while being the most
flexible approach, leave a lot of problems open to the user.
Scene graphs have become an important paradigm for the construction of
extensible and flexible general-purpose interactive 3D graphics systems.
They are used in a large variety of application areas and on a large
variety of platforms, ranging from wearable computers to large clusters
or graphics super-computer systems. The current developments in computer
graphics hardware and algorithms offer new opportunities and present new
challenges for these general-purpose systems.
Many new algorithms are still developed in stand-alone systems, which
prevents them from being used and evaluated in a more general context or
being integrated into applications. One reason may be that designing and
implementing a clean, integrated system is not a simple task. To quote
Fred Brooks: "It took us a year to develop the different algorithms for
our walkthrough system. It took us another year to make them work
together."
On the other hand more specialized systems like game engines are getting
increasingly powerful and are being used for a number of different, not
necessarily game-related, tasks. Architectural walkthroughs, museum
exhibits and other installations have been realized using game engines.
The goal of this symposium is to give the participants an opportunity to
present and discuss current work in the area of interactive 3D graphics
systems, their concepts, designs and implementations.
Topics include but are not limited to:
- Scene Graphs and Game Engines: Applicability and Limits
- Clustering
- Multi-Thread Handling
- High-Level Shading
- Efficient Geometry Data Management
- Abstraction of Hardware Differences
- Flexible and Efficient Graphics State Handling
- Creation and Consistency of Secondary Hierarchies
While we welcome contributions based on the OpenSG system, this is by no
means a prerequisite.
The submitted papers should cover original work and can present research
projects and results as well as experiences from actual applications.
Location
The workshop will be held at the Fraunhofer Institute for Computer
Graphics (Fraunhofer IGD) in Darmstadt, Germany.
Deadlines
The deadline for paper submissions is Friday, February 28th 2003. All
submissions will be electronic, details will be posted in advance of the
deadline.
The results of the reviews will be sent out on March 14th.
Publication
The style should follow the Eurographics Digital Library styleguides
(see the Guidelines for details). The maximum length of the papers is 8
pages.
(Pending) The presented papers will be published in the Eurographics and
ACM Digital Libraries. Selected papers will collected in a special issue
of Computers & Graphics.

Dear OpenSGers, SIGGRAPH 2002 is over, and again we worked hard to present OpenSG in the best possible manner. We had our own booth (see the attached pictures), where we presented our demos and talked to people about OpenSG. The big topic was clustering, which we showed on different configurations. One was just two or three laptops running Linux and/or Windows, the other was a cluster using an sgi Octane2 and an HP J6000, which can be seen on the right side of the images, to prove that we can handle heterogeneous configurations too. At this point I would like to thank the OpenSG Forum-member sgi and the not-yet Forum member HP very warmly for providing us with the demo machines. The demo we ran was an example for a very dynamic scene, a flowfield particle tracer, to show that dynamic scenes are possible on clustered systems. Other new stuff being demonstrated (which has subsequently been integrated into the CVS tree) was a simple volume renderer using 3D textures and view-dependent slicing (the OSGSlicer node core), which was also well received. The booth was pretty busy most of the time, and we made some interesting new contacts as well as talking to some well known users and contributors. We also took the chance to intensify our contacts to HP and Sun. We got our clustering to work on the HP Visualize Cluster, but only after the show had ended (they were understandably reluctant to install new stuff on a hot demo machine). We also got in contact with Sun about getting machines for porting to Solaris, which will hopefully happen in time before 1.2. 1.2 is slated for early October, and the single most important topic for it is documentation. Only little features and bugfixes on top of what is currently in the CVS are planned, cleanup and documentation is what we'll be working on for the next two months. All in all it was an enjoyable and successfull SIGGRAPH, even though the preparation and booth duty took a toll on everybody. I would like to thank Gerrit Voss, Marcus Roth and Johannes Behr for all their work and support in making SIGGRAPH happen.

Hi folks,
due to me defending my PhD (which I did sucessfully, if I might say so :) and
some last minute technical problems (why do these things always occur AFTER
the distributions are built? :-/) later than expected but nonetheless here it
is: OpenSG 1.1.0.
The main changes are ports that required a very extensive overhaul, but now
we can support Microsoft Visual Studio .NET including their own compiler and
IDE, as well as Visual Studio 6 using the Intel compiler. We also have ports
for HP-UX and MAC OS X (partially). Many thanks to Gerrit for taking on all
these different compilers with all their quirks (and they have a lot of
those).
The other big news are the first results of OpenSG PLUS: the support for
clustering. See Cluster/ in the Source for details. Thanks to Marcus Roth for
his efforts.
Some other additions:
configure: local extensions, separate include/lib dirs,
Binary File format: relatively compact files, extremely fast load
Particle NodeCore
Text: for statistics only right now, not on Windows, needs Freetype1
Statistics: pretty general statistics collector
Geometry: secondary color & multi-texture support, new striper,
LatLongSphere
State: CubeTexture, 3D Texture, Register Combiners support
Name: convenience functions to create/read/remove name attachments
fcdEdit: added Decorator capabilities
Fly and TrackballNavigator
Foregrounds: Image, Grab, FileGrab
Backgrounds: Image, Passive, Sky (a la VRML)
PassiveWindow/Viewport/Camera: easy integration into other frameworks
CameraDecorators: ShearedStereo, Projection
StereoBufferViewport
and some more.
So take a look, enjoy and tell us your experience. Note that this is a
developer release, so the documentation hasn't changed much. Yeah, I know, it
needs to. Don't worry that's the main thing to do for 1.2, and that will
bring big changes in that respect. But until we're there you're welcome to
ask us on the mailing lists or on IRC.
Yours
Dirk Reiners

Dear subscribers, I'm happy (really happy) to inform you that OpenSG 1.0 has been released. Together with a fully redone website you can find and download it at www.opensg.org. OpenSG 1.0 is, as the name implies, the first real release, and a stable one at that. Thus the focus was not on features or performance, but rather on stabilizing things and writing documentation. We have a ~50 page starter guide now, which explains the most important aspects of OpenSG. It's not a tutorial for 3d graphics beginners, it would actually be beneficial to know another scenegraph before reading it. But not really neccessary. ;) We also have some tutorials that show how to do things in OpenSG which can serve as a starting point for your own experiments. As a somewhat more complex application we have an osgSceneViewer which can show the scenegraph of the loaded model (supported formats: VRML, OBJ, OFF, RAW). The system performs quite decently given the amount of time we spent on optimizations, but it's probably not the fastest yet. Try it and see for yourself. And if you find a model that's awfully slow, we'd appreciate sending it to us so that we can see where the bottlenecks are. :) In any case, take a look, enjoy and tell us what you think.

Dear subscribers, this is an invitation for all those of you who are you in Germany (or are willing to come to Germany ;). Next Wednesday, September 19th, we will have an OpenSG information event. We will present the current state of OpenSG, give information about the activities at SIGGRAPH and the 1.0 version, and also show demos of how OpenSG is used in different applications, including a technology demo of the new clustering support. There will also be technology talks about SIGGRAPH with a focus on Real-Time Rendering and VR, and 2 talks by OpenSG PLUS partners about the activities and approaches for NURBS tesselation and Volume Rendering, which will be integrated into OpenSG in the course of the project. See the attached program for details. The event will take place in Darmstadt, at the Fraunhofer Institute for Computer Graphics. Info how to get there is appended, too. As the number of participants is limited, please send an email to ste...@ig... if you intend to come, so that we can reserve your spot. Thanks for your interest, and stay tuned for 1.0.

Dear subscribers, we've been pretty quiet lately, which was due to the fact that we've been very busy. OpenSG will be presented at SIGGRAPH in our own booth 2167, showing the current state of the system. It's getting very interesting... The OpenSG Bird of a Feather session will be held on Tuesday, at 18:15 in the Convention Center. As we had to move the date due to collisions with other events the room is not fixed yet. Take a look at the BOF board or drop into our booth on Tuesday and we'll know the details.

Hello everybody, as SourceForge has modified their directory structure, all currently checked out CVS setups don't work anymore. The directory for the CVS root has moved from /cvsroot/OpenSG to /cvsroot/opensg. To fix it you need to run the following shell scripts from the top of your OpenSG directory structure: For csh/tcsh: foreach i (`find . -name CVS`) sed -e "s|cvsroot/OpenSG|cvsroot/opensg|" < $i/Root > q mv q $i/Root sed -e "s|cvsroot/OpenSG|cvsroot/opensg|" < $i/Repository > q mv q $i/Repository end For bash/sh/ksh: for i in `find . -name CVS` do sed -e "s|cvsroot/OpenSG|cvsroot/opensg|" < $i/Root > q mv q $i/Root sed -e "s|cvsroot/OpenSG|cvsroot/opensg|" < $i/Repository > q mv q $i/Repository done Sorry for the confusion, it's all to make SourceForge a better system.

Dear subscribers, I'm happy to announce the availability of the OpenSG beta version. It is visibily improved compared to the alpha version, mainly due to the support of materials and textures. But a number of other things have changed that make using the system easier, e.g. a first test for using configure to simplify installation, or using our initial VRML97 loader to get data into the system. It is available right now from http://www.opensg.org/download.html and will move onto Sourceforge over the next couple days. Take a look, this is quite a bit more useful than the alpha version. There are still lots of things to do, though, and we're looking forward to getting things done together with you.

Dear subscribers, the OpenSG Alpha version is now available from SourceForge at http://download.sourceforge.net/OpenSG/opensg-0.1a.tgz . It is a slight refining of the Alpha version I sent out before, which compiles (and runs) under IRIX, Linux and NT now (using gmake and the Intel compiler). I can't stress it enough: it's definitely work in progress code. To make our announced date (and stick to it this time) we brought it to a point where it does something. But it's not complete, it's not spectacular, it's not optimized and it's not yet at a point where I would start thinking about doing applications on top of it. So if you want to switch your multi-million lines-of-code system to a new renderer tomorrow or need something to build you thesis on, don't bother downloading. I just want to prevent you getting at this with wrong expectations and dropping it for all time if it doesn't meet them. Take a look at it, try it, and tell us what you like and dislike. Put it up on the Forums on SourceForge (http://sourceforge.net/forum/?group_id=5283), we'll be checking that frequently. Thank you for your interest Dirk -- -- -- Dirk Reiners re...@ig..., Dir...@gm... -- OpenSG Forum http://www.opensg.org -- Rundeturmstrasse 6 http://www.igd.fhg.de/~reiners -- D-64283 Darmstadt All standard disclaimers apply. -- Truth is stranger than fiction because fiction has to make sense. |

Hello everybody, apparently there was a double booking for the room, so the OpenSG BOF has been relocated to Room 352. Hope you'll read this in time Dirk -- -- -- Dirk Reiners re...@ig..., Dir...@gm... -- OpenSG Forum http://www.opensg.org -- Rundeturmstrasse 6 http://www.igd.fhg.de/~reiners -- D-64283 Darmstadt All standard disclaimers apply. -- Truth is stranger than fiction because fiction has to make sense. |

Dear subscribers, this is your chance to find out everything that you always wanted to know about OpenSG but were afraid to ask. If you want to know who we are, what the goal of the system is, what we're up to and if it'll be able to do all the things you always dreamed of, here you go. We'll be hosting an OpenSG BOF at SIGGRAPH, where we're open to address questions and discuss the past, present and future of the system. The whole core team will be present, so every topic is covered. It will be on Monday the 24th, from 17:00 to 18:00, right after the courses. The location is in the convention center, room 285. Hope to see many of you there Dirk P.S.: Sorry for duplicates, I'm trying to cover everybody who showed interest and that might includes some people more than once. -- -- -- Dirk Reiners re...@ig..., Dir...@gm... -- OpenSG Forum http://www.opensg.org -- Rundeturmstrasse 6 http://www.igd.fhg.de/~reiners -- D-64283 Darmstadt All standard disclaimers apply. -- Truth is stranger than fiction because fiction has to make sense. |

Dear subscribers, we are happy to annouce the availability of the first OpenSG version. It's still alpha, so don't expect too much. Most of the main data structures are there, basic rendering works, as well as basic multithreading. Interfaces are subject to change, although the general concepts are not expected to change much. There are a number of test programs including a simple viewer for raw triangle files. No effort has been spent on optimization, so don't bother benchmarking. Now is a good time to take a look and see if it might be able to do what you're looking for. And if it's not, tell us why. Just in case you want to contribute: this is where it starts. I don't know where it will end, but I think it's going to be an interesting ride. It is distributed as a tarball that compiles and runs under IRIX and Linux. Windows support for the Intel VTune compiler is coming soon. If you're interested, please send me an email (di...@op...) and I will send you the tarball. Thanks for your patience and support The OpenSG Team -- -- -- Dirk Reiners re...@ig..., Dir...@gm... -- OpenSG Forum http://www.opensg.org -- Rundeturmstrasse 6 http://www.igd.fhg.de/~reiners -- D-64283 Darmstadt All standard disclaimers apply. -- Truth is stranger than fiction because fiction has to make sense. |
