A method is provided for rendering pixels based on a certain type of Bezier curve, called a simple Bezier arch. The method uses an implicit function to determine whether each pixel in a domain triangle containing the arch is on the arch, on one side of the arch, or on the other side. The function's parameters can be linearly interpolated to allow efficient rendering of the triangle by a GPU. A method is also provided for applying the aforementioned method to render pixels, based on a non-linear Bezier curve having at most four control points, by subdividing the curve into simple Bezier arches as necessary. A computing device for performing these methods is also provided. |
