Hi Zhu,
How to set the normals of IndexedGeometry ?
You can use com.sun.j3d.utils.geometry.NormalGenerator
But then you have to build the geometry with GeometryInfo.
GeometryInfo gi = new GeometryInfo(GeometryInfo.TRIANGLE_ARRAY) ;
gi.setCoordinates(coordinates);
gi.setCoordinateIndices(indices);
NormalGenerator ng = new NormalGenerator();
ng.generateNormals(gi);
Stripifier st = new Stripifier(); // Eventually
st.stripify(gi);
IndexedGeometryArray ig = gi.getIndexedGeometryArray(true);
Hope this helps.
