    # Bottomface
    count = 0
    face = []
    for x in range(numPoints):
        face.append(count)
        count = count + 1
    faces.append(face)
    
    # Topface
    # TODO: correct winding
    count = 0
    face = []
    for x in range(numPoints):
        face.append(count+numPoints)
        count = count + 1
    faces.append(face)
