If you're using OpenDX and have some nifty pictures you'd like to share, contact us to get them added to the gallery.
- October 14, 2007 - The CVS is again available. After being off-line at IBM for 4 months, it is now back up and an OpenSource repository. Check it out in the Developers section.
- September 11, 2006 - The new OpenDX DVD is available for purchase from VIS, Inc.
- September 9, 2006 - New mailing lists are up for use. Please come join us there if you prefer e-mail over user forums.
- August 30, 2006 - OpenDX 4.4.4 is now available. Binaries for the highest demand operating systems are now available. See the ChangeLog for the list of changes.
- March 22, 2005 - Jerry Hagon has updated his font converter script with some helpful documentation changes. Click here to download it. He also has a new dvidx which allows dvi output to be imported into OpenDX. Check out DXfontutils for more info.
- July 1, 2004 - VIS, Inc. has updated its book, OpenDX: Paths to Visualization, to version 2 reflecting the changes in OpenDX 4.3.
"As a scientific visualization producer at the Cornell Theory Center and as
a business consultant and trainer, I've been producing scientific,
engineering, and business data visualizations and video for the past 10
years. As a rule, the data to be visualized is multiparametric,
multidimensional, and temporal. Many of the data sets are many megabytes or
even gigabytes in size; in others, the data size is small, but the visual
representation of the data is complex. Since 1991, the single most
important and useful software for this purpose has been Data Explorer. The
DX data model and generic functionality of its many modules permits me to
cast every data visualization problem in similar terms, even if the
underlying data and the output imagery looks very different from one
discipline to another. This means that the more you use DX, the more your
personal toolkit (previous programs, macros, tricks) and skill set
improves, allowing you to conceptualize and tackle any visualization
problem that you encounter.
The DX data model and the many available filters for third party data
formats enable you to quickly import disparate data sets, in most cases,
without changing the way the original data is organized. And many times, I
have seen that people have adopted the DX data model as a superior
organizing schema for their data, especially if their data format was
simply one of convenience and not suited to scale or encompass later
changes in their research program.
As a certified IBM DX workshop trainer, I have been pleased to see how
quickly beginners pick up the fundamentals of DX and bring it to bear on
solving their visualization problems. Yet, with the complete extensibility
of both the data model and the function set (through the addition of
custom-programmed modules), DX is profound as well. This is usually the
reaction of those workshop attendees who have had experience with other
I would encourage anyone involved in adding visualization capability to
their research program to acquire Data Explorer, run the tutorials, examine
the online information and extensive help files, and discover the potential

Data Explorer in Action
RAHD Oncology Products uses Data Explorer in commercial radiation treatment planning products. The Multidimensional Viewer (MDV) creates 3D structures from CT contours and 3D beams from beam parameters and blocking, and allows interactive review of structures, treatment beams, dose, CTs, and dose volume histograms. The 3D Beam Modifier (BM) provides interactive beam design in 3D, both manually and automatically, with interactive review of structures, treatment beams, CTs, and digital radiographs. It provides real time interaction and modification of select objects simultaneously in multiple windows. Each product utilizes DX very differently (both employ a separate Motif GUI):
The MDV utilizes the DX data flow, VPE, and user interface environments.
The BM is built entirely in C, using only the DX libraries (no data flow, VPE, or user interface).
