Systems, methods, and computer-readable storage media are provided for efficient real-time ink stroke smoothing, trajectory prediction, and GPU-leveraged rendering of ink stroke input. First and second ink points are received and an active Bézier approximation is computed based thereupon. Sequentially later in time that the first and second ink points, a third ink point is received. It is determined whether the third ink point adequately fits the active Bézier approximation. Where it is determined that the third ink point adequately fits, an updated active Bézier approximation is computed that includes the first, second and third ink points. Where it is determined that the third ink point fails to adequately fit, a different new Bézier approximation is computed that includes the third ink point but not the first and second ink points. Leveraging a GPU, a smoothed ink stroke based upon the Bézier approximation(s) is rendered.
