I load a vrml file which is a cylinder (d=105mm, h=180mm) to java 3d viewer but I can not see it clearly. The code is like following,
 
    Transform3D viewTrans = new Transform3D();
    Transform3D eyeTrans = new Transform3D();
 
    sceneBounds = (BoundingSphere)branchRoot.getBounds();
    Point3d center = new Point3d();
    Vector3d temp = new Vector3d(center);
    viewTrans.set(temp);
 
    temp.x = 0.0;
    temp.y = 0.0;
    temp.z = 200;

    eyeTrans.set(temp);
    viewTrans.mul(eyeTrans);

    universe.getViewingPlatform().getViewPlatformTransform().setTransform(viewTrans);
 
 
only when I set temp.z = 200 I can see something otherwise nothing shows up. I also loaded a small cylinder(r=1) before and set temp.z = 10 and it works great.
 
Anyone can tell me anything wrong within my code?
