A software development environment created at the GE Research
and Development Center significantly reduces the time and cost
to prototype and create software applications.
The ability to create software applications rapidly and cheaply is an important
requirement. LYMB is an object-oriented development environment aimed at
developing applications that require combining graphics-based user interfaces,
visualization, and rapid prototyping. These are some of LYMB's main features:
- A library of over 600 classes of objects that have been reused or extended
for applications in engineering design, medical imaging, command and control,
quality control, and maintainability/service.
- The rapid creation of prototypes achieved by combining an interpreted
environment with object classes that are compiled for fast execution.
- Highly portable environment that runs on Unix workstations, including HP,
Sun, SGI, DEC, and IBM. LYMB has direct links to specific workstation display
renderers and also integrates directly with Motif and X Windows.
- A built-in mechanism to distribute applications over a network of servers
- Visualization - LYMB has been used to create a variety of
visualization applications: Visage is a generic tool for understanding 2D and
3D data sets from engineering design, medical scanning, and test measurements;
Decimate is a tool for reducing the number of polygons required for visualizing
geometry models; and Swept Volumes is a tool for determining the surface that
a physical object sweeps as it moves along a specified path.
- Medical - Biomagnetism is an approach to diagnose disease
conditions in the brain and the heart by measuring very small magnetic fields
generated by currents in these organs. LYMB is being used for real-time waveform
displays (256 channels of data) and analysis of the time-varying magnetic fields
- Command and Control - LYMB has been used to create
graphics-based user interfaces rapidly and to simulate the communications among
display consoles on surface ships and submarines. The time saving over
approaches is a factor of five.
- Air Traffic Control - Airport traffic control of aircraft on
the ground is an important problem because of the growing number of scheduled
flights and weather conditions such as fog and wind shear. A 3D visualization
of airport traffic control demonstrates the benefits of automation and new
such as radar, to meet traffic demands and improve safety.
- Entertainment - LYMB has been used by NBC to show "ideal
on 3D shaded displays of a golf green, enhancing the TV viewer's perspective of a
The full selection of building blocks, or classes, available with
it the flexibility and speed for developing today's applications.
- LYMB on a PC
All the functionality of LYMB ported to run on the large installed
base of Windows NT and Windows 95 computers. Providing state of the
art visualization to the PC platform.
