Show CHAPTER 1 INTRODUCTION 1.1 Introduction The Matte volumes system is an integrated system for visualization and exploration of three-dimensional(3D) scalar field data. It provides scientists with graphical tools for interactively navigating through the volume data and conveying the information about the area of interest for further rendering. It uses techniques such as volumes seeds and volume seedlings and auxiliary mattes to visualize the regions of interest. Scientific visualization is a technique used to create high quality images from multidimensional scalar and vector datasets, usually for the purpose of gaining insight into a scientific problem. It transforms the numeric into the geometric, enabling researchers to observe their simulations and computations and the sampled data. Visualization enriches the process of scientific discovery and fosters profound and unexpected insights. Scientific visualization embraces both image understanding and image synthesis; i.e., it is a tool both for interpreting image data fed into a computer, and for generating images from complex multidimensional data-sets. It studies those mechanisms in humans and computers which allow them in concert to perceive, use, and communicate visual information. Visualization unifies largely independent but convergent fields of computer graphics, image processing, computer-aided design, user interface design, computer vision, and signal processing. Today's data sources are such fire hoses of information that all we can do is gather and warehouse the numbers they generate. High volume data sources include super computers; orbiting satellites returning earth resource; military intelligence; weather and astronomical data; space craft sending planetary and interplanetary |
