Space Station Freedom data management system growth and evolution report

The Information Sciences Division at the NASA Ames Research Center has completed a 6-month study of portions of the Space Station Freedom Data Management System (DMS). This study looked at the present capabilities and future growth potential of the DMS, and the results are documented in this report. Issues have been raised that were discussed with the appropriate Johnson Space Center (JSC) management and Work Package-2 contractor organizations. Areas requiring additional study have been identified and suggestions for long-term upgrades have been proposed. This activity has allowed the Ames personnel to develop a rapport with the JSC civil service and contractor teams that does permit an independent check and balance technique for the DMS

Migrating to an Object-Oriented Graphics API

We provide an analysis of the elements needed in an object--oriented scene graph API and give a contrasting, non--competing, exposition of how such elements are implemented in modern graphics and geometry API's. The objectives are to show the sensibility of the adopted design options and to give the flavors, both common and distinct, of various modern scene graph API's
