Abstract
Publisher Summary This chapter presents a survey of basic principles and advanced technologies in data visualization, with a focus on Virtual Reality (VR) hardware and software. Most data visualization relies on computer graphics to present data in innovative ways, so that obscured abstract or complex information become obvious and easy to comprehend through images and/or animations. In computer graphics, unlike drawing by hand, accurate description of the shape of the object needs to be drawn—a list of vertices or a geometric description (such as a specific curve equation) that can be used to find all the points of the object. Therefore, instead of just having a picture, there is a model that describes the object as initial data saved in the memory. The chapter also introduces principles of computer graphics and graphics software tools, and provides some data visualization technologies with a few examples. It discusses VR and software, and highlights some applications that exploit an integration of visualization and VR.
