Drishti: a volume exploration and presentation tool

Abstract

Among several rendering techniques for volumetric data, direct volume rendering is a powerful visualization tool for a wide variety of applications. This paper describes the major features of hardware based volume exploration and presentation tool -<i> Drishti</i>. The word, <i>Drishti</i>, stands for vision or insight in Sanskrit, an ancient Indian language. <i>Drishti</i> is a cross-platform open-source volume rendering system that delivers high quality, state of the art renderings. The features in <i>Drishti</i> include, though not limited to, production quality rendering, volume sculpting, multi-resolution zooming, transfer function blending, profile generation, measurement tools, mesh generation, stereo/anaglyph/crosseye renderings. Ultimately, <i>Drishti</i> provides an intuitive and powerful interface for choreographing animations.
