User Quote

"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 visualization programs.

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 of visualization!"

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).
