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.

The // ViewingPlatform class creates a handy hook to do this // called "platform geometry". The PlatformGeometry class is // subclassed off of BranchGroup, and is intended to contain // a description of the 3D platform itself... PLUS a headlight! // So, to add the headlight, create a new PlatformGeometry group, // add the light to it, then add that platform geometry to the // ViewingPlatform. // BoundingSphere allBounds = new BoundingSphere(new Point3d(0.0, 0.0, 0.0), 100000.0); PlatformGeometry pg = new PlatformGeometry(); headlight = new DirectionalLight(); headlight.setColor(White); headlight.setDirection(new Vector3f(0.0f, 0.0f, -1.0f)); headlight.setInfluencingBounds(allBounds); headlight.setCapability(Light.ALLOW_STATE_WRITE); pg.addChild(headlight); viewingPlatform.setPlatformGeometry(pg); // // Create the 3D content BranchGroup, containing: // // - a TransformGroup who's transform the examine behavior // will change (when enabled). // // - 3D geometry to view // // Build the scene root BranchGroup sceneRoot = new BranchGroup(); // Build a transform that we can modify exampleSceneTransform = new TransformGroup(); exampleSceneTransform.setCapability(TransformGroup.ALLOW_TRANSFORM_READ); exampleSceneTransform.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE); exampleSceneTransform.setCapability(Group.ALLOW_CHILDREN_EXTEND); // // Build the scene, add it to the transform, and add // the transform to the scene root // if (debug) System.err.println(" scene..."); Group scene = this.buildScene(); exampleSceneTransform.addChild(scene); sceneRoot.addChild(exampleSceneTransform); // // Create a pair of behaviors to implement two navigation // types: // // - "examine": a style where mouse drags rotate about // the scene's origin as if it is an object under // examination. This is similar to the "Examine" // navigation type used by VRML browsers. // // - "walk": a style where mouse drags rotate about // the viewer's center as if the viewer is turning // about to look at a scene they are in. This is // similar to the "Walk" navigation type used by // VRML browsers. // // Aim the examine behavior at the scene's TransformGroup // and add the behavior to the scene root. // // Aim the walk behavior at the viewing platform's // TransformGroup and add the behavior to the scene root. // // Enable one (and only one!) of the two behaviors // depending upon the current navigation type. // examineBehavior = new ExamineViewerBehavior(exampleSceneTransform, // Transform // gorup // to // modify exampleFrame); // Parent frame for cusor changes examineBehavior.setSchedulingBounds(allBounds); sceneRoot.addChild(examineBehavior); walkBehavior = new WalkViewerBehavior(exampleViewTransform, // Transform // group to // modify exampleFrame); // Parent frame for cusor changes walkBehavior.setSchedulingBounds(allBounds); sceneRoot.addChild(walkBehavior); if (navigationType == Walk) { examineBehavior.setEnable(false); walkBehavior.setEnable(true); } else { examineBehavior.setEnable(true); walkBehavior.setEnable(false); } // // Compile the scene branch group and add it to the // SimpleUniverse. // if (shouldCompile) sceneRoot.compile(); universe.addBranchGraph(sceneRoot); reset(); }
