Glyph Toolbox for Immersive Scientific Visualization

摘要

We describe a set of software, The Glyph ToolBox (GTB), for creating three dimensional (3D) glyphs. This software defines a single, general format for describing glyphs; it includes color and opacity parameters as well as location information. GTB is written with the UNIX philosophy as well as location information. GTB is written with the UNIX philosophy of small reusable programs that are text based for portability and efficiency. Version 1.0 of GTB currently contains simple figures, manipulation functions, extrusion functions, meta-figure functions, as well as additional functions such as text creators. We describe four applications for the glyph toolbox: a visualization of the Monk's problem, a relationship highlighter, a smiley emoticon, and a display algorithm for concave surfaces. We separate the creation of the glyphs from their display. We provide a filter that can incorporate the GTB format into their environment, making the creation and use of glyphs uniform across viewers.
