Cube Problem

russ12

Hi all, I have a problem with my cube below i cant rotate it, I have tried keylistener() but I cant seen to get it to work can anyone help please !!!! i just dont no how to get it to rotate.

public class Cube {

// private Color3f lightBlue;
private Color3f white;
private BranchGroup group;
private SimpleUniverse universe;


public Cube() {

white = new Color3f(1.0f, 1.0f, 1.0f);

universe = new SimpleUniverse();
group = new BranchGroup();

// Method the method below.

addCube(0.3f, 0.3f, 0.3f, new Vector3f(-1.0f, -1.0f, -1.0f), white);
addCube(0.3f, 0.3f, 0.3f, new Vector3f(1.0f, -1.0f, -1.0f), white);
addCube(0.3f, 0.3f, 0.3f, new Vector3f(1.0f, 1.0f, -1.0f), white);
addCube(0.3f, 0.3f, 0.3f, new Vector3f(-1.0f, 1.0f, -1.0f), white);

addCube(0.3f, 0.3f, 0.3f, new Vector3f(-1.0f, -1.0f, 1.0f), white);
addCube(0.3f, 0.3f, 0.3f, new Vector3f(1.0f, -1.0f, 1.0f), white);
addCube(0.3f, 0.3f, 0.3f, new Vector3f(1.0f, 1.0f, 1.0f), white);
addCube(0.3f, 0.3f, 0.3f, new Vector3f(-1.0f, 1.0f, 1.0f), white);

// addCube(0.3f, 0.3f, 0.3f, new Vector3f(-1.0f, -0.4f, 1.0f), white);
// addCube(0.3f, 0.4f, 0.3f, new Vector3f(-1.0f, 0.3f, 1.0f), white);


DirectionalLight light1 = new DirectionalLight(white, new Vector3f(0.0f, 2.0f, -12.0f));

light1.setInfluencingBounds(new BoundingSphere(new Point3d(0.0, 0.0, 0.0), 100.0));

group.addChild(light1);


Transform3D look = new Transform3D();

look.lookAt(new Point3d(3.0, -7.0, 10.0), new Point3d(0.0, 0.0, 0.0), new Vector3d(4.0, 0.0, 0.0));

look.invert();

universe.getViewingPlatform().getViewPlatformTransform().setTransform(look);

universe.addBranchGraph(group);
}


}
public void addCube(float x, float y, float z, Vector3f position, Color3f color) {

TransformGroup tg = new TransformGroup(); // a single spatial transformation, can position, orient, and scale all of its children.
Transform3D trans = new Transform3D(); // used for translations, rotations, and scaling and shear effects.

Appearance app = new Appearance();

Material mat = new Material(); // how this cube appears on screen ie. shininess

mat.setDiffuseColor(color);
mat.setSpecularColor(color);
app.setMaterial(mat);

Box b = new Box(z, y, x, app);

trans.setTranslation(position);
tg.setTransform(trans);
tg.addChild(b);

group.addChild(tg);


}

public static void main(String[] args) {
new Cube();


}



}

You have a render loop, which renders a cube using the values defined in Position, Rotation and Translation. These need to have methods to alter them, so you can pass values via an interface using a keylistener or whatever, or the update method of the object will read some values that are changed by a keylistener.

I need to see a render loop of some sort to figure out what the hell is happening above though.
