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. if (debug) System.err.println(" ground..."); Appearance groundApp = new Appearance(); Material groundMat = new Material(); groundMat.setAmbientColor(0.3f, 0.3f, 0.3f); groundMat.setDiffuseColor(0.7f, 0.7f, 0.7f); groundMat.setSpecularColor(0.0f, 0.0f, 0.0f); groundApp.setMaterial(groundMat); tr = new Transform3D(); tr.setScale(new Vector3d(8.0, 8.0, 1.0)); TextureAttributes groundTexAtt = new TextureAttributes(); groundTexAtt.setTextureMode(TextureAttributes.MODULATE); groundTexAtt.setPerspectiveCorrectionMode(TextureAttributes.NICEST); groundTexAtt.setTextureTransform(tr); groundApp.setTextureAttributes(groundTexAtt); if (groundTex != null) groundApp.setTexture(groundTex); ElevationGrid ground = new ElevationGrid(11, // X dimension 11, // Z dimension 2.0f, // X spacing 2.0f, // Z spacing // Automatically use zero heights groundApp); // Appearance // // Build the scene using the shapes above.
