Details

Come to the VR Juggler BoF at SIGGRAPH 2004 to see the new and exciting features of VR Juggler 2.0. There has been much work done over the past year to increase both the functionality and ease of use of VR Juggler. This will give you a great oppertunity to ask questions that you may have and provide us with input to direct the future of VR Juggler. Below is a list of the major changes that have occurred over the past year.

VRJConfig: Custom Editors

Much work has been put into the design of high-level editors for complex tasks such as device configuration including proxies, aliases, and screen placement for projection VR systems.

VRJConfig: Wizards

Wizards have been added into VRJConfig to simplify the creation of general purpose configurations.

Config Element Versioning

Automatic updating of out-of-date configuration elements has been added. VRJConfig can detect when a configuration element is out of date with respect to its definition. Through the magic of XSLT, the configuration element can be transformed into the new version automatically.

Performance Monitoring

Added the ability to acquire performance statistics in order to analyze the different parts of your application and VR Juggler. The interface is very clean and easy to use. There are three macros that can be used: VPR_PROFILE("MyDraw"), VPR_PROFILE_HISTORY("MyDraw", num), and VPR_PROFILE_RESULTS().

Microsoft Speech Recognition Driver

Added support for an additional speech recognition input type. This allows both a direct stream of recognized words and access to a grammer matching mechanism.

Building Device Drivers

Related to people writing their own device drivers, the Gadgeteer build system has been revamped to make it much, much easier for users to compile their device driver plug-ins with all the correct options. It is now possible for developers to write a four-line makefile that will build a device driver correctly on all supported platforms.

VR Juggler Dynamic Application Loader/Launcher

The basic idea with this application is to allow remote launching of dynamically loaded VR Juggler application objects. In other words, it realizes a goal we have had for a long time: a VR Juggler daemon.

Build System: External Dependencies

With each release of VR Juggler there is now a dependency package that contains all required external dependencies. This makes it much easier for the end user to install and VR Juggler quickly.

Build System: Windows Build

Cygwin is no longer required for any part of building the Juggler Project, including VR Juggler applications. The code is built now using a Visual Studio solution that ties together a bunch of Visual C++ projects. Unlike the Cygwin build, the Visual Studio build supports both debug and release binaries. There has also been a Tkinter visual front end added to make the process of specifing all build settings easier.

Linux Joystick Driver

A new Linux Joystick driver has been added to allow input from any supported joystick or gamepad.

We look forward to seeing you in Los Angeles.
