Embodiments facilitate the production of a B-spline curve that approximates a set of N-dimensional (position, pressures, tilt, etc.) discrete input samples recorded by a digital input device. Iterative noise filtering and B-spline subdivision processes are performed within a dynamic window of recent samples. A vector representation is produced at interactive rates after each new sample is captured, thus producing results that are comparable to what the same artist would expect if drawing on paper.
