Hi I have a scene that has a white ball(3d graphics) and the scene is on my frame also the north of my frame there is a panel which has a button and by clicking on the button the ball will be red.how can I do that?please help me thanks
this is the code that creates a white sphere:
protected void floatingWhiteSphere() {
Color3f black = new Color3f(0.0f, 0.0f, 0.0f);
Color3f white = new Color3f(1.0f, 1.0f, 1.0f);
Color3f specular = new Color3f(0.9f, 0.9f, 0.9f);
Material blueMat = new Material(white, black, white, specular, 25.0f);
// sets ambient, emissive, diffuse, specular, shininess
blueMat.setLightingEnable(true);
Appearance blueApp = new Appearance();
blueApp.setMaterial(blueMat);
// position the sphere
Transform3D t3d = new Transform3D();
t3d.set(new Vector3f(0, 1, -5));
TransformGroup tg = new TransformGroup(t3d);
tg.addChild(new Sphere(1.0f, blueApp)); // set its radius and appearance
sceneBG.addChild(tg);
}
