Description:

This animation features a static image of a contour surface on the left and an oblique 3-D view of the same area. Upon starting the animation, by clicking adjacent arrows, a surface of water begins to rise. By examining the views in both windows, a simulated flood shows how contour lines trace out equal elevations and how concave/convex undulations in the contour lines would be represented in 3-D. The animation can be paused and rewound to stress important points.
