Re: [JAVA3D] setNorminalViewingTransform() doubt

[Alessandro Borges]

Hi .
you must disable the call to setNominalViewingTransform(); or you camera
will go back to old value ;-)
And you also must get your viewing platform from your simpleUniverse as
show below
Try  this time:

SimpleUniverse simpleU = new SimpleUniverse(canvas3D);
 BranchGroup scene = createSceneGraph(canvas3D, simpleU);
 scene.compile();
 Transform3D t3d = new Transform3D();
  double viewDistance = 10.0;
   t3d.set(new Vector3d(0.0, 0.0, viewDistance));
simpleU.getViewingPlatform().getViewPlatformTransform().setTransform(t3d);
// disable below line or the above lines will lost effect
//  simpleU.getViewingPlatform().setNominalViewingTransform();
 simpleU.addBranchGraph(scene);
}

Hi,  thanks Alessandro

SimpleUniverse simpleU = new SimpleUniverse(canvas3D);
  BranchGroup scene = createSceneGraph(canvas3D, simpleU);
  scene.compile();
  Transform3D t3d = new Transform3D();
   double viewDistance = 10.0;
    t3d.set(new Vector3d(0.0, 0.0, viewDistance));
 viewingPlatform.getViewPlatformTransform().setTransform(t3d);
  simpleU.getViewingPlatform().setNominalViewingTransform();
  simpleU.addBranchGraph(scene);
 }
still got error. how to fix it?Please help..

Faithfully,

    double viewDistance = myZDistance; // put your double Z value here.

    viewingPlatform.getViewPlatformTransform().setTransform(t3d);
