Class AnalyticSurfaceDemo

java.lang.Object
  gov.nasa.worldwindx.examples.ApplicationTemplate
      gov.nasa.worldwindx.examples.analytics.AnalyticSurfaceDemo

public class AnalyticSurfaceDemo
extends ApplicationTemplate

Illustrates how to configure and display a 3D geographic grid of scalar data using the World Wind AnalyticSurface. Analytic surface defines a grid over a geographic Sector at a specified altitude, and enables the caller to specify the color and height at each grid point.

This illustrates three key AnalyticSurface configurations:

• Displaying a static data set where each grid point uses color and height to indicate the data's magnitude.
• Displaying data that varies by color over time on the terrain surface.
• Displaying data that varies by color and height over time at a specified altitude.
