The purpose of the Gumbo open source project is to develop a Java
library/toolkit/framework that supports rich applications
with compelling 2D/3D user interfaces. Rather
than being an end unto itself this work serves as an evolving toolkit
combining widgets, data models, and ingredients from various sources to
form a rich "gumbo" for the rich application developer.
This work expands on the principles and Java 3D code base described in the book "3D User Interfaces with Java 3D" published by Manning. This work also includes a generous contribution of RCP code from Meyer Sound. Overall this project emphasizes direct manipulation in desktop applications; however, passive visualization and immersive VR applications may also benefit.
focusing on GUI widgets and a particular graphics dimensionality or
technology, this project instead offers architectural patterns and
building blocks for MVC, delegation, event routing, in-scene
manipulation, navigation, graph visualization, interaction dynamics,
etc. Fundamental to this work is an abstraction of the
graphics layers, allowing the patterns and techniques to work with
Swing, SWT, Java 2D, OpenGL, Java 3D, and what may come.

The major difference in this release is that the source code is now under the LGPL license.
One minor difference in this release is that the source code and library have been located in separate directories, "src" and "lib", respectively. Also, the class j3dui.utils.app.AppDisplay has been modified to avoid the "null graphics context" message in the book release.
As with the book release, javadoc can be found in the "docs"
directory, and the easiest way to run the examples (if you are using
Windows) is to
double-click on the .bat file in an "examples" directory.
