VisAD HDF-5 Data Adapter
The VisAD HDF-5 Data Adapter is now available. It enables VisAD applications
to read data from HDF5 files.
VisAD (from the University of Wisconsin-Madison) is a Java toolkit for
constructing interactive and collaborative visualization and analysis of
numerical data.
The VisAD HDF-5 Data Adapter consists of Java classes which call the NCSA
Java HDF-5 Interface (JHI5), which calls the native HDF5 library. It
follows the VisAD standard interface, so it can be used by any VisAD
application.

JHI5 version 1.1 for HDF5-1.2.1
The Java HDF5 Interface (JHI5) version 1.1 for HDF5-1.2.1 is now
available.
JHI5 version 1.1 is a bug fix release. The changes in JHI5 1.1 are:
- H5.H5Sselect_elements() -- The arguments were incorrectly passed from
Java to C. This is fixed.
- Object references and region references did not work correctly.
- The class HDF5Reference was eliminated. All object references should
be passed as Java byte[], length 8 (object reference) or 12 (region
reference).
- All H5R* interfaces changed to use byte[] instead of HDF5Reference.
- Region references are implemented and work correctly.
- The Unix Makefile built the class HDF5CDataTypes, but failed to include
it in 'jhdf5.jar' when running 'make install'. This is fixed.

Pre-compiled binaries for HDF5-1.2.1
HDF5-1.2.1 was released in December, 1999. However, at that time only
the source code was available and not the pre-compiled binaries for
the platforms tested.
The pre-compiled binaries can now be downloaded from:
ftp://ftp.ncsa.uiuc.edu/HDF/HDF5/current/bin/
