Under direction of the Office of Naval Research, the Naval Research Laboratory’s Code 5770 produced the SIMDIS 3-D Analysis and Display Toolset to the US Department of Defense community. SIMDIS provides support for analysis and display of test and training mission data to more than 4000 users. SIMDIS runs on Windows, Linux, and Sun Microsystems workstations with hardware accelerated 3-D graphics and provides identical execution and "look and feel" for all supported platforms.
