User Quote

In a nutshell, I use DX extensively for many types of applications using both large and small data sets...

I'm basically using it in a 2-d world for remote sensing data applications. 99% of the people in this area use IDL. DX stands out better in 3-d applications, but from my experience it is faster and more reliable than IDL even in 2-d applications (very large data sets). I use DX for many data types, especially unstructured and polyline and I also use DX as a debugging tool for just about anything. If an algorithm isn't doing what I think it should, just start a new DX program from scratch and in minutes you can be analizing the problem.

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).
