This always happens instantly, so there is no way of animating it provided by OpenSG. If you want to animate it moving, you will need to move it in small increments as time progresses (animating it yourself), maybe also based on the time that has elapsed ... :-) > In my project, I want to move a WRL file along the Z > axis 20.

Hi, In my project, I want to move a WRL file along the Z axis 20. If I use the setTranslate (0,0,20), how can I control the speed of moving? Or, is there other more convenient way to do that? Thanks!

Hello osgPeople, Sorry for being slightly off-topic, but I just want to make you aware that we organize the HEyeWall-Day on April 29th here at Fraunhofer-IGD in Darmstadt/Germany, where the HEyeWall-System is presented to a broader audience. HEyeWall is a stereoscopic, high-resolution tiled display, consisting of 48 projectors, a huge Linux-Cluster resulting in a single, semless huge desktop of 4.8m by 2.4m. The final resolution of our installation is 6144x3072 pixel or 18 Megapixel. And yes, OpenSG runs nicely on it! If you are interested, check out www.heyewall.de. There you will find more information about the system, pictures, the agenda of the HEyeWall-Day and the possiblity for online registration (german/english). Hope to see some of you on April 29th here in Darmstadt.

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, 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. Visit www.opensg.org for information and download instructions.

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.

Dear OpenSG interested, I'm happy to announce the 3. OpenSG Birds of a Feather session at SIGGRAPH 2002. It will be held on Tuesday July 23rd at 19:15 in the Alamo Ballroom, Salon A of the Marriott Riverwalk, right across from the Convention Center. It is right after the Scenegraph BOF and in the same room, so you can get a high dose of scene graphs without having to move. :) We will be presenting the current state of OpenSG and the developments during the last year as well as giving a glimpse of things to come. There will also be live demos of the major developments. The core team will be on site to answer all the questions you ever had about OpenSG (and some you never dared to ask). If you have things you want to talk about and/or show that you've done using OpenSG you're very welcome to do so. There will be a projector on site if you want to show slides and/or demos. OpenSG itself will be represented at the exhibition again with its own booth, number 4063. We will be showing our latest demos and results, especially in the cluster area. We hope to see you there Dirk & The OpenSG Team -- -- -- Dirk Reiners OpenSG Forum di...@op... -- The OpenSG Open Source Scenegraph: http://www.opensg.org -- Announcements: http://lists.sf.net/lists/listinfo/opensg-announce ************************************************************************** ** Visit us at SIGGRAPH 2002 in Booth 4063, or visit the BOF on Tuesday ** ************************************************************************** |

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, this is the first installment of the OpenSG Newsletter. After 1.0 we took a little time off (or rather got back to our other duties ;), so that this letter is a little later than expected, and doesn't contain as much finished news, but more about work in progress. I hope you find it interesting nonetheless. Style Cleanup ============= We decided to do the code cleanup now and not postpone it until 1.1. Thus everybody's busy reformatting the exisiting code to conform to our style guide, which can be viewed at http://opensg.sourceforge.net/cgi-bin/twiki/view/Main/StyleGuide. It's a dirty job, but at some point you just gotta do it. Navigator ========= The new navigator is nearing completion. It will feature a standard virtual trackball and in addition a fly mode to fly through larger models. We'll also throw in something similar to the standard first person shooter mode, but that will need a little support from the window system. We'll se that turns out. It will be available standalone and will also replace the old Trackball in the SimpleSceneManager. Particles ========= The first steps of a particle node are done. The particle node will render multiple viewer-aligned quads specified by position, color and size. The first application is visualising molecules, but other uses are obvious when looking at any current game. Text ==== I've seen some images of OpenSG-based text. It is still pretty early, but we're optimisitic to get in it soon. It is going to be based on Freetype, and thus will be able to read any Truetype font. More about that in the next news. That's it for now, hope to see you again next week. Until then, keep on coding. Yours The OpenSG Team -- -- -- Dirk Reiners OpenSG Forum di...@op... -- The OpenSG Open Source Scenegraph: http://www.opensg.org -- Announcements: http://lists.sf.net/lists/listinfo/opensg-announce |
