visualization graphics visualization of how a car deforms in an asymmetrical crash using finite element analysis visualization or visualisation see spelling differences is any technique for creating images diagrams or animations to communicate a message visualization through visual imagery has been an effective way to communicate both abstract and concrete ideas since the dawn of humanity examples from history include cave paintings egyptian hieroglyphs greek geometry and leonardo da vincis revolutionary methods of technical drawing for engineering and scientific purposes visualization today has everexpanding applications in science education engineering eg product visualization interactive multimedia medicine etc typical of a visualization application is the field of computer graphics the invention of computer graphics may be the most important development in visualization since the invention of central perspective in the renaissance period the development of animation also helped advance visualization overview the ptolemy world map reconstituted from ptolemys geographia circa 150 indicating the countries of serica and sinae china at the extreme right beyond the island of taprobane sri lanka oversized and the aurea chersonesus southeast asian peninsula charles minards information graphic of napoleons march the use of visualization to present information is not a new phenomenon it has been used in maps scientific drawings and data plots for over a thousand years examples from cartography include ptolemys geographia 2nd century ad a map of china 1137 ad and minards map 1861 of napoleons invasion of russia a century and a half ago most of the concepts learned in devising these images carry over in a straightforward manner to computer visualization edward tufte has written three critically acclaimed books that explain many of these principles computer graphics has from its beginning been used to study scientific problems however in its early days the lack of graphics power often limited its usefulness the recent emphasis on visualization started in 1987 with the publication of visualization in scientific computing a special issue of computer graphics since then there have been several conferences and workshops cosponsored by the ieee computer society and acm siggraph devoted to the general topic and special areas in the field for example volume visualization most people are familiar with the digital animations produced to present meteorological data during weather reports on television though few can distinguish between those models of reality and the satellite photos that are also shown on such programs tv also offers scientific visualizations when it shows computer drawn and animated reconstructions of road or airplane accidents some of the most popular examples of scientific visualizations are computergenerated images that show real spacecraft in action out in the void far beyond earth or on other planets dynamic forms of visualization such as educational animation or timelines have the potential to enhance learning about systems that change over time apart from the distinction between interactive visualizations and animation the most useful categorization is probably between abstract and modelbased scientific visualizations the abstract visualizations show completely conceptual constructs in 2d or 3d these generated shapes are completely arbitrary the modelbased visualizations either place overlays of data on real or digitally constructed images of reality or make a digital construction of a real object directly from the scientific data scientific visualization is usually done with specialized software though there are a few exceptions noted below some of these specialized programs have been released as open source software having very often its origins in universities within an academic environment where sharing software tools and giving access to the source code is common there are also many proprietary software packages of scientific visualization tools models and frameworks for building visualizations include the data flow models popularized by systems such as avs iris explorer and vtk toolkit and data state models in spreadsheet systems such as the spreadsheet for visualization and spreadsheet for images applications scientific visualization simulation of a raleightaylor instability caused by two mixing fluids further information scientific visualization as a subject in computer science scientific visualization is the use of interactive sensory representations typically visual of abstract data to reinforce cognition hypothesis building and reasoning data visualization is a related subcategory of visualization dealing with statistical graphics and geographic or spatial data as in thematic cartography that is abstracted in schematic form scientific visualization is the transformation selection or representation of data from simulations or experiments with an implicit or explicit geometric structure to allow the exploration analysis and understanding of the data scientific visualization focuses and emphasizes the representation of higher order data using primarily graphics and animation techniques it is a very important part of visualization and maybe the first one as the visualization of experiments and phenomena is as old as science itself traditional areas of scientific visualization are flow visualization medical visualization astrophysical visualization and chemical visualization there are several different techniques to visualize scientific data with isosurface reconstruction and direct volume rendering being the more common educational visualization educational visualization is using a simulation to create an image of something so it can be taught about this is very useful when teaching about a topic that is difficult to otherwise see for example atomic structure because atoms are far too small to be studied easily without expensive and difficult to use scientific equipment information visualization relative average utilization of ipv4 further information information graphics information visualization concentrates on the use of computersupported tools to explore large amount of abstract data the term information visualization was originally coined by the user interface research group at xerox parc and included jock mackinlay practical application of information visualization in computer programs involves selecting transforming and representing abstract data in a form that facilitates human interaction for exploration and understanding important aspects of information visualization are dynamics of visual representation and the interactivity strong techniques enable the user to modify the visualization in realtime thus affording unparalleled perception of patterns and structural relations in the abstract data in question knowledge visualization the use of visual representations to transfer knowledge between at least two persons aims to improve the transfer of knowledge by using computer and noncomputerbased visualization methods complementarily examples of such visual formats are sketches diagrams images objects interactive visualizations information visualization applications and imaginary visualizations as in stories while information visualization concentrates on the use of computersupported tools to derive new insights knowledge visualization focuses on transferring insights and creating new knowledge in groups beyond the mere transfer of facts knowledge visualization aims to further transfer insights experiences attitudes values expectations perspectives opinions and predictions by using various complementary visualizations see also picture dictionary visual dictionary product visualization product visualization involves visualization software technology for the viewing and manipulation of 3d models technical drawing and other related documentation of manufactured components and large assemblies of products it is a key part of product lifecycle management product visualization software typically provides high levels of photorealism so that a product can be viewed before it is actually manufactured this supports functions ranging from design and styling to sales and marketing technical visualization is an important aspect of product development originally technical drawings were made by hand but with the rise of advanced computer graphics the drawing board has been replaced by computeraided design cad caddrawings and models have several advantages over handmade drawings such as the possibility of 3d modeling rapid prototyping and simulation visual communication visual communication is the communication of ideas through the visual display of information primarily associated with two dimensional images it includes alphanumerics art signs and electronic resources recent research in the field has focused on web design and graphicallyoriented usability visual analytics visual analytics focuses on human interaction with visualization systems as part of a larger process of data analysis visual analytics has been defined as the science of analytical reasoning supported by the interactive visual interface its focus is on human information discourse interaction within massive dynamically changing information spaces visual analytics research concentrates on support for perceptual and cognitive operations that enable users to detect the expected and discover the unexpected in complex information spaces technologies resulting from visual analytics find their application in almost all fields but are being driven by critical needs and funding in biology and
