I actually solved it myself. But it isn't really smart done.
I think there should be some method that's more obvious.

Code to scale is included and you should use the getMinMaxVal
function included in mail from yesterday (mail with subject:
"Re: [JAVA3D] Extacting Shape3D's from the FltLoader"
Please make a remark, that I have rotated the coordinetes during
input, therefore I have the z - y switch of axis:
BranchGroup brGrp = (BranchGroup)switchGroup.getChild(i);
System.out.println("minmax: Number of children of BranchGroup =
" + brGrp.numChildren());
TransformGroup trGrp = (TransformGroup)brGrp.getChild(0);
Enumeration enum = brGrp.getAllChildren();
MinMaxVal minmax = new MinMaxVal();
getMinMaxVal(enum,minmax);
System.out.println("Min :" + minmax.min[0] + " " + minmax.min[1]
+ " "+ minmax.min[2]);
System.out.println("Max :" + minmax.max[0] + " " + minmax.max[1]
+ " "+ minmax.max[2]);
double x_mid = (minmax.max[0] + minmax.min[0])*0.5;
double y_mid = (minmax.max[1] + minmax.min[1])*0.5;
double z_mid = (minmax.max[2] + minmax.min[2])*0.5;
System.out.println("Mid :" + x_mid + " " + y_mid + " "+ z_mid);
Transform3D trans = new Transform3D();
trGrp.getTransform(trans);
System.out.println("minmax: originally transform = " + trans);
Vector3d translation = new Vector3d();
trans.get(translation);
// trans.setTranslation(translation);
double scale_val = 0.3;
double old_scale = trans.getScale();
trans.setScale(scale_val);
System.out.println("minmax: old_scale = " + old_scale + "
scale_val = " + scale_val);
System.out.println("minmax: translation = " + x_mid * (old_scale
- scale_val) + " " +
y_mid * (old_scale - scale_val) + " " + z_mid
* (old_scale - scale_val) + " " );
translation.x += x_mid * (old_scale - scale_val);
translation.y += z_mid * (old_scale - scale_val);
translation.z -= y_mid * (old_scale - scale_val);
trans.setTranslation(translation);
trGrp.setTransform(trans);
System.out.println("minmax: modified transform = " + trans);

Dear all.
I have tried to do the same thing but failed. Probably due to my own
incompetence.
Any one out there that have a snippet of code to share?
