The Biomedical Problem Solving Environment, or BioPSE is an integrated software tool for solving bioelectric field problems. It brings together and allows interaction between the modeling, computation, and visualization phases of a bioelectric field simulation. Though it is robust enough to support expert-users and novices alike, it is easy to move around in. This software environment empowers researchers of bioelectric fields to analyze their data, their methods, and the full range of their problem space in ways they had never before considered. No longer needing to spend the majority of their time translating among data file formats for various programs or having to manually enter data over and over into their programs, scientists are freed to apply their expertise where it makes the most sense - to steer an integrated computational system, to visually explore their data, to experiment with model parameters. When such tools integrate seamlessly, they fade into the background, the user is freed to concentrate on the problem at hand rather than on the software tools.

map3d is a scientific visualization application developed at the CVRTI to display and edit complex, three-dimensional geometric models and the scalar data associated with those models. map3d was originally written in ANSI-C using the Graphics Library (GL) from Silicon Graphics Inc. Recently, we have developed and released a new version of map3d based on the OpenGL standard that runs on SGI, Linux, and Windows systems. The map3d interface provides interactive display of both geometry and data assigned to elements of that geometry. The program can read multiple surfaces, each with multiple associated potential/current data files.

map3d addresses a unique niche in visualization by combining high performance interactive graphics with extensive quantitative data interrogation tools. The user can view three-dimensional time signals in modes that emphasize either the spatial or the temporal aspects of the data and move quickly back and forth between these views.
