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.
