The NormalGenerator utility works only on GeometryInfo objects.
Other utilities are the triangulator and stripifier. After the
utilities operate on the GeometryInfo object, the resulting
geometry can be used in a Shape3D object.
All of this is covered in Section 3.3 of the tutorial, including
a complete (simple) example. An excerpt of the example appears
below.
Find the Java 3D Tutorial "Getting Started with the Java 3D API" at
java.sun.com/products/javamedia/3d/collateral
GeometryInfo gi = new GeometryInfo(GeometryInfo.POLYGON_ARRAY);
gi.setCoordinates(coordinateData);
gi.setStripCounts(stripCounts);
Triangulator tr = new Triangulator();
tr.triangulate(gi);
NormalGenerator ng = new NormalGenerator();
ng.generateNormals(gi);
Stripifier st = new Stripifier();
st.stripify(gi);
Shape3D part = new Shape3D();
part.setAppearance(appearance);
part.setGeometry(gi.getGeometryArray());
