To quickly test to see if it is the normals, try altering the appearance for
your pyramid like this:
Appearance ap = ...
PolygonAttributes pa = new PolygonAttributes();
pa.setCullFace(PolygonAttributes.CULL_NONE);
ap.setPolygonAttributes(pa);
If the polygon now shows up, your problem is your normals.

It sounds like it could be the Normals. They can be tricky.
Check them next.
