Re: [JAVA3D] Zooming

Hi,

I think what you need is a MouseZoom object.
Set the TransformGroup object as the argument
to  the MouseZoom object.

MouseZoom zoomObj = new MouseZoom();
zoomObj.setTransformGroup(t3d);
zoomObj.setSchedulingBounds(    new BoundingSphere());

 After this, adding your Shape3D objects to t3d should
do the work.

Regards,

Anand

Subject:  [JAVA3D] Zooming



Hi,

I have a scenegraph object containing some lines, circles, arcs, texts etc. I
wish to do some zooming and hence I did the follg to the scenegraph's
transformgroup

    Transformgroup t3d;
  t3d.setTranslation(new Vector3d(0,0,0));
  t3d.setScale(scale);
  t3d.setTranslation(new Vector3d(test.x,test.y,test.z));//screen origin

  scenegraph.transformgroup.setTransform(t3d);


With this I am able to zoom line and circle. But the arc, text etc are not
zoomed but only translated.. Can anyone tell me whether what I did is correct or
not? If yes, why it is not zooming all the objects? Is my approach correct?
