    // Build the ground. Use a trick to get better lighting
    // effects by using an elevation grid. The idea is this:
    // for interactive graphics systems, such as those
    // controlled by Java3D, lighting effects are computed only
    // at triangle vertexes. Imagine a big rectangular ground
    // underneath a PointLight (added below). If the
    // PointLight is above the center of the square, in the real
    // world we'd expect a bright spot below it, fading to
    // darkness at the edges of the square. Not so in
    // interactive graphics. Since lighting is only computed
    // at vertexes, and the square's vertexes are each
    // equidistant from a centered PointLight, all four square
    // coordinates get the same brightness. That brightness
    // is interpolated across the square, giving a *constant*
    // brightness for the entire square! There is no bright
    // spot under the PointLight. So, here's the trick: use
    // more triangles. Pretty simple. Split the ground under
    // the PointLight into a grid of smaller squares. Each
    // smaller square is shaded using light brightness computed
    // at the square's vertexes. Squares directly under the
    // PointLight get brighter lighting at their vertexes, and
    // thus they are bright. This gives the desired bright
    // spot under the PointLight. The more squares we use
    // (a denser grid), the more accurate the bright spot and
    // the smoother the lighting gradation from bright directly
    // under the PointLight, to dark at the distant edges. Of
    // course, with more squares, we also get more polygons to
    // draw and a performance slow-down. So there is a
    // tradeoff between lighting quality and drawing speed.
    // For this example, we'll use a coarse mesh of triangles
    // created using an ElevationGrid shape.
