Hola Ra�l, te mando un c�digo donde yo fijo la anchura de la l�nea de
una objeto en malla de alambre (wireframe). Espero que te ayude.
Saludos desde Albacete.... ;)

Box2 Pieza = new Box2(0.2f, 0.2f, 0.1f);
Appearance app = new Appearance();
// Seleccionar el color en el que va a aparecer el wireframe
Color3f objColor = col; // "col" es un par�metro
ColoringAttributes ca = new ColoringAttributes();
ca.setColor(objColor);
app.setColoringAttributes(ca);
// Aqu� es donde cambio lo de la anchura de la l�nea.
LineAttributes la = new LineAttributes();
la.setLineWidth(3);
la.setLineAntialiasingEnable(false); // Qu�talo o perderas
much�simo rendimiento.
app.setLineAttributes(la);
// Esto es para que salga con wireframe.
PolygonAttributes pa = new PolygonAttributes();
pa.setPolygonMode(pa.POLYGON_LINE);
pa.setCullFace(pa.CULL_NONE);
app.setPolygonAttributes(pa);
