Hi all
I have got an appliation that I import VRML shapes and add them to the scene
at run time. One of the issues I have is that when the user moves the
starting shape it is tricky for them just to manipluate the shape back to the
starting position. What I want to do is place a button on the swing panel
that resets the scene back to it's starting posistion and rotation etc.
The problem I have is that I don't seam to be able to change the view of my
scene I have lood at the Selman book and tried to include some parts of the
code but it all has no effect I am proberly constructing it wrong so if
someone could point out what I have done wrong I would "luv it"
canvas = new Canvas3D(SimpleUniverse.getPreferredConfiguration());
simpleUniverse = new SimpleUniverse(canvas);
ViewPlatform vp = new ViewPlatform();
TransformGroup viewTG = new TransformGroup();
Transform3D viewT3d = new Transform3D();
Transform3D eyeT3d = new Transform3D();
View view = new View();
PhysicalBody pb = new PhysicalBody();
PhysicalEnvironment pe = new PhysicalEnvironment();
view.setPhysicalBody(pb);
view.setPhysicalEnvironment(pe);
//setting up TransformGroup for view
viewT3d.setTranslation(new Vector3d(0.0,0.0,10.0));
//set up a default viewing platform
view.attachViewPlatform(vp);
view.setBackClipDistance( 300 );
view.setFrontClipDistance( 0.3 );
// Background color
worldBounds = new BoundingSphere(new Point3d(),100.0);
addLighting(worldBounds);
back.setApplicationBounds( worldBounds );
back.setCapability(Background.ALLOW_COLOR_WRITE);
back.setColor( new Color3f(0.7f, 0.7f, 0.95f ));
/*
Point3d centre = new Point3d();
worldBounds.getCenter(centre);
double radius = worldBounds.getRadius();
Vector3d temp = new Vector3d(centre);
viewT3d.set(temp);
System.out.println("temp = "+temp);
double eyeDist = 1.4*radius/ Math.tan(Math.toRadians(40)/2.0);
temp.x = 0.0;
temp.y = 0.0;
temp.z = eyeDist;
eyeT3d.set(temp);
viewT3d.mul(eyeT3d);
*/
//create scene
canvas.setCursor(new Cursor(Cursor.HAND_CURSOR));
BranchGroup root = new BranchGroup();
BranchGroup shape = new BranchGroup();
shape = (BranchGroup)getScene();
//add all groups to root node
viewTG.addChild(vp);
viewTG.setTransform(viewT3d);
root.addChild(viewTG);
root.addChild(shape);
root.compile();
SimpleUniverse.addBranchGraph(root);
