This paper presents a new methodfor providing interactive shape control of interpolating B‐splines. The CAD designer can directly interact with geometric entities defined on the B‐spline at any interpolated data point; shape adjustments can be performed either globally or locally. Our approach is based on Bλ‐splines of order k (λ,k ≥1), i.e. λ‐reparametrized, classical B‐splines. The method presented can be easily generalised to surfaces defined either as tensor products or by using the skinning technique; interactive shape control can be provided in both surface parametric directions.
