Hello,
actually we have the problem that we want to know the coordinates of an object which
has already been rotated by MouseRotate. Is there a way to come to the new
coordinates????
We started with a LineArray which contains the vertices and edges of our 3D-object.
The LineArray is part of the Shape3D object.
public ColorCubeOwn1(Appearance app)
{
LineArray cube = new LineArray(24,
LineArray.COORDINATES | LineArray.COLOR_3);
cube.setCoordinates(0, verts); // verts contains the vertices of the
object!!
cube.setColors(0, colors);
shape = new Shape3D(cube, app);
}
The Shape3D object is part of a TransformGroup
TransformGroup tg = new TransformGroup();
tg.addChild( shape );
The TransformGroup is part of a rootBranchGroup
// First create the BranchGroup object
BranchGroup rootBranchGroup = new BranchGroup();
// Then add it to the rootBranchGroup
rootBranchGroup.addChild(tg);
The TransformGroup is added to the MouseRotator and the MouseRotator is added to the
rootBranchGroup!
MouseRotate myMouseRotate = new MouseRotate();
myMouseRotate.setTransformGroup(tg);
myMouseRotate.setSchedulingBounds(new BoundingSphere());
rootBranchGroup.addChild(myMouseRotate);
The 3D object can be rotated with the MouseRotator .
Our problem is now to get the changed coordinates of the already rotated 3D object.
We tried to read it from the LineArray.getCoordinates() method.
But this was not successful. We received only the data of the start position of the 3D
object.
We used the LineArray directly as well as fetched it from the Shape3D object (
getGeometry() )
or from the TransformedGroup ( getChild() )!!
How is it possible to get the changed coordinates?????????
Any help would be greatly appreciated.
regards
Dieter Weimer
