Hmm, I have never seen that page with cylinder packing. Thanks!

By the way:

for n in range(nPoly):

	phi1,phi2=n*phiStep,(n+1)*phiStep
	def pt(angle,radius,z):

		return radius*sin(angle),radius*cos(angle),z

	a,b,c,d=pt(phi1,rCyl,0),pt(phi2,rCyl,0),pt(phi1,rCyl,hCyl),pt(phi2,rCyl,hCyl)

	o.bodies.append([
		utils.facet([a,b,c]),

		utils.facet([b,c,d])])

These strings can be now changed by utils.facetCylinder(). That should be
easier.
