Chapter 7. Interacting with 3D Data
In this chapter, we move up to apps that involve generating, visualizing, and interacting with data on a 3D grid. A common approach to visualization of any function of three variables starts by sampling the function on a grid, so almost any 3D contour plot produces a 3D data grid at some point in the process. In addition, 3D data grids are produced either experimentally or numerically by a variety of devices and in a wide variety of applications, including the following:
• Volumetric medical scanners such as computed tomography (CT) and positron emission tomography (PET) systems. CT scans are also used for inspection of manufactured parts.
• Direct numerical simulation (DNS) of fluid dynamics, including aerodynamics ...
