The guided spline approach to surface construction separates surface design and surface representation by constructing local guide surfaces and sampling these by splines of moderate degree. This paper explains a construction based on tessellating the domain into V-shaped regions so that the resulting C~2 surfaces have G~2 transitions across the boundaries of the V-shapes and consist of tensor-product splines of degree (6,6) with patches of degree (4,4) forming a central cap.
