If anyone is using X3D M6, you might be interested:

GeometryArray ga = (GeometryArray)g;

A couple of comments on this. You have stripped away all texture
coordinate and color information, and regenerated the normals(ignoring
the VRML creaseAngle field). So as a general solution this will not be
enough. You might being seeing some performance improvement just by not
sending texture coordinate data over.
Currently Xj3D is not stripifying its data. We are still looking into
how best to represent the data. As a static solution this is fine, but
for dynamic content calling the stripifier every frame would suck.
