We propose a method for computing the Minkowski sum of two free-form surfaces, given in a tensor product B-spline representation in R3. The Minkowski sum (typically a three dimensional volume), is represented by its boundary surface(s), also referred to as the envelope. The envelope is obtained via an algebraic equation solving approach (in the parameter space of the input geometries), followed by...
