How to stretch one svg path ?

[liyihongcug]

I can use sample way to make 2d svg picuture.
But I need 3d path.

final String path = "M22.395-127.223c-4.492,11.344-4.688,33.75,0,44.883"
+ "c-11.328-4.492-33.656-4.579-44.789,0.109c4.491-11.354,4.688-33.75,0-44.892"
+ "C-11.066-122.63,11.262-122.536,22.395-127.223z";

My requirement is to add one height value(z=50) in all svg path points.
Thus (22.395,127.223) ==========> (22.395,127.223,50).
Other points are likes above.

But I find it doesn't work in SVGPathFragment.java.
1 for (int j = 0; j <= subdiv; j++) {
Vector3 point = new Vector3();
subPath.calculatePoint(point, (float) j / (float) subdiv);
point.z=50; // I add it
points.add(point);
}
2 I don't know how to stretch it to polygon whose height is 100. (please stretch it)
