The main OpenSG website has moved to http://opensg.vrsource.org . It's aTrac-based system that simplifies user contributions and better integrates source and issue tracking.

We did release 1.6 a while ago, we just never put out a news item for it. Sorry about that.

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.... read more

We proudly announce the 1.1.0 release of the OpenSG scene graph system. The main changes are support for Microsoft Visual Studio .NET and VS6 (using Intel compiler), and the support for Clusters. There are lots of other changes, see the CHANGELOG for details.

OpenSG 1.0 released

OpenSG is a scenegraph system for realtime rendering tasks. Besides the standard goal of high
performance OpenSG targets multithread-safe data handling coupled with high
flexibility and extensibility. In addition to portability (Irix, Linux,
Windows), support of a wide range of hardware from standard PCs to high-end
multi-pipe Workstations is planned. As this is just version 1.0 not
everything is done yet, but due to funding from a reserach contract,
sustained development is guaranteed. A number of computer graphics research
institutions are actively working on moving the system beyond the state of
the art to include features like clustering, subdivision surfaces, occlusion
culling and more. See the OpenSG PLUS page for details.

Due to circumstances beyond our control the 1.0 release is going to be delayed. The September 10th date is already passed, but we're still commited to a September date.

Stay tuned.

Thanks

Dirk

The release here is quite old (Feb/01), and a lot has changed. The next release will be available soon, so please come back in a couple weeks or subscribe to the announce mailinglist to get informed when it happens.If you really can't wait you can try the CVS... ;)

Thanks

Dirk

The last release is pretty old and has quite a lot of problems. Most of which are fixed already in the CVS, in addition to the numerous new features. The next release is expected shortly after SIGGRAPH (Aug 13-17), so come back after that to get a good impression.

If you want to be reminded automatically, just subscribe to the Announce mailing list. It's very low traffic, primarily for announcing new releases.... read more
