3D Data Visualization

You can represent some kinds of data as a three-dimensional graph. For example, certain mathematical functions can be visualized this way. So can some sets of physical measurements (e.g., height information from map data). Figure 1-21 shows an example.

3D plot of data ()

Figure 17-31. 3D plot of data (Figure F-2)

To display data in this form, you need to write code that will generate a mesh from the data. Let's look at an example that creates the MeshGeometry3D shown in Figure 1-21 from a two-dimensional array of floating-point numbers. To be able to display a 3D model, we will of course need a Viewport3D. Example 17-26 shows the XAML for a window containing a Viewport3D with a camera and some light sources.
