As a corner-cutting subdivision scheme,Lane-Riesefeld algorithm possesses the concise and unified form for generating uniform B-spline curves:vertex splitting plus repeated midpoint averaging.In this paper,we modify t...

We estimate error bounds between ternary subdivision curves/surfaces and their control polygons after k-fold subdivision in terms of the maximal differences of the initial control point sequences and constants that de...
For the problem of constructing smooth functions over arbitrary surfaces from discretedata, we propose to use Loop's subdivision functions as the interpolants. Results on theexistence, uniqueness and error bound of th...
