December 1, 1994ResearchSRC Report 129Obliq-3DTutorial and Reference ManualMarc A. Najorkd i g i t a lSystems Research Center130 Lytton AvenuePalo Alto, California 94301Systems Research CenterThe charter of SRC is to advance both the state of knowledge and the state of the artin computer systems. From our establishment in 1984, we have performed basicand applied research to support Digital’s business objectives. Our current workincludes exploring distributed personal computing on multiple platforms, network-ing, programming technology, system modelling and management techniques, andselected applications.Our strategy is to test the technical and practical value of our ideas by buildinghardware and software prototypes and using them as daily tools. Interesting systemsare too complex to be evaluated solely in the abstract; extended use allows us toinvestigate their properties in depth. This experience is useful in the short term inrefining our designs, and invaluable in the long term in advancing our knowledge.Most of the major advances in information systems have come through this strategy,including personal computing, distributed systems, and the Internet.We also perform complementary work of a more mathematical flavor. Some ofit is in established fields of theoretical computer science, such as the analysisof algorithms, computational geometry, and logics of programming. Other workexplores new ground motivated by problems that arise in our systems ...
