RAI Java Products and Development Projects
The Radio Astronomy Imaging Team
is applying Java as an important component technology to its various
infrastructure
research initiatives. This document describe some of the Java
development projects we are involved in and how they are being
applied.
Primary Development Projects
- NCSA Horizon
Image Data Browsing Package
- NCSA Horizon is a toolkit for building applets and applications
that browse scientific images. It consists of reusable classes
as well as ready-to-run applets. The basic design is independent
of the data format and includes support for several data format
types. Targeted for data providers, scientists, and
educators, the aim of this package is to make it easy to
provide sophisticated browsing capabilities for scientific
images over the web or from local disk.
This technology is being developed to support RAI's Networked
Instrument and Advanced Visualization initiatives. It is being
employed by the
NCSA Astronomy Digital Image Library (ADIL) to support
sophisticated browsing tool for Library Images. It will also
be integrated into the radio
interferometer data pipeline system and
NCSA Emerge for
Project
30.
- NCSA
Astro3Vis
- This project provides tools for creating 3D visualizations of
astronomical images using VRML. It is actually made up of two
products that can work independently or together for added
capabilities. First, the
VRML
Server allows one to create the 3D visualizations over the
Web and download the results which can be viewed with any VRML
2.0 browser. The second product, Astro3D,
is a pure-Java VRML viewer based on the Java3D API.
This work is being carried out through a collaboration with Paul
Rajlich of the
Visualization and
Virtual Environments Group and Steve Pietrowicz of the
Java 3D
Group at NCSA.
- The SciArch Package
- Java will be an important component of the
radio interferometer data pipeline
system as the platform for user and administrative
interaction with its distributed services. The first product to
result from this development is the Data Retrieval Tool (DaRT) for
downloading observational data from the Archive.

NCSA Habanero
- This package provides a Java environment for turning ordinary
applets into collaborative applets. The
Horizon
development team is working with Habanero developers to provide
the Horizon package with transparent support of collaboration.
