Elements of Scientific Visualization Systems

Abstract

The paper discusses elements of logical models of graphical user interfaces used in both universal and specialized scientific visualization systems. Criteria of expressiveness of programming language that are discussed in “Structure and Interpretation of Computer Programs” book are applied to graphical interfaces. It is shown that graphical interfaces allow user to operate on same digital substance and with same logical approaches as in textual programming languages. Both use basic elements, allow their combination, and support the procedure of abstraction. Authors suggest considering this aspect when developing graphical interfaces. Then, idea of modifiers (known also as behaviors, effects, so on) is discussed. Idea of extensions (known also as plugins, modules, and applications) is also discussed. Some methods of programming of scene dynamics are presented. Also languages and ontologies of scientific visualization are discussed, e.g. models for editing visualization pipeline: adding data to projects, filtering of that data, and methods of description of data representation on screen.
