VR Juggler 2.2.1 represents a significant improvement to the VR Juggler 2.2 release series, due in no small part to feedback, bug reports, and fixes from users. All users of VR Juggler 2.0.x and 2.2.0 are strongly encouraged to update to this release. This release is binary compatible with VR Juggler 2.2.0, and most applications should not need to be recompiled to take advantage of this new version. Applications whose application object is derived from vrj::OsgApp are the exception. In particular, there has been a minor API change to vrj::OsgApp to fix a compile error. The return type of vrj::OsgApp::getSceneViewDefaults() has changed from osgUtil::SceneView::Options to unsigned int, and overrides of that method must be changed to reflect this new signature.

Allen Bierbaum and Aron Bierbaum, core developers of VR Juggler, today successfully defended their Ph.D. dissertation and master's thesis respectively. This day was a long time in the making, and they should be congratulated for their hard work and success.

After more than two years of development and testing, VR Juggler 2.2.0 has finally hit the streets. VR Juggler 2.2 represents a significant improvement over the VR Juggler 2.0 release series, and we think that users will be very happy with the results. The improvements and new features include better cluster scalability and performance; more robust error handling and recovery; support for Cocoa on Mac OS X; versioned directories and binaries to allow for parallel installations; support for 64-bit Windows; support for OpenSG 2.0; and enhanced support for multisampling in OpenGL windows.

In general, most applications should migrate from VR Juggler 2.0 to 2.2 quite seamlessly, but there are bound to be exceptions. All users and application developers are strongly encouraged to read the VR Juggler 2.2 Migration Guide carefully. Note especially that configuration files need to be updated for proper migration.

Maestro is a client/server architecture intended to provide easy methods to launch applications across a cluster and to manage a cluster. Maestro provides a single coherent view of the entire cluster through a cross-platform GUI application written in Python using PyQt. Each application that can be launched on the cluster has an associated configuration file (called a "stanza") that stores all needed information. Maestro is designed with VR Juggler in mind so that using VR Juggler on a cluster can be greatly simplified.

See the Maestro download page for more information.

VR Juggler has a new website! This was done to separate user and developer content. The new main site tries to be purely informational while our new VR Juggler Developer Trac Site aims to provide up to date information about the project status, integrated bug tracking, and developer related documentation. The old site will continue operating at http://oldsite.vrjuggler.org while we transition the old wiki's to the developer site.
