Abstract:
A method for rendering a shape partially defined by quadratic Bézier curves computes the winding number with respect to one or more closed contours to determine whether a sample position is colored. Numerical robustness is achieved by classifying the controls points of each Bézier curve in order to partition the set of all possible Bézier curves into eight equivalence classes that can each be processed in the same manner. A small table of binary values specifies whether the roots of a classified Bézier curve are eligible to modify the winding number at a particular pixel location.

Claim (Index 7):
One or more computer-readable storage media containing program instructions describing a method for causing a computer to render a shape defined at least in part by one or more closed contours composed at least in part of one or more quadratic curves, comprising:\n computer program code for identifying the B\u00e9zier control points for each said quadratic curve; computer program code for classifying each said control point based on its position with respect to at least one axis; computer program code for selecting at least one root of each said quadratic curve with respect to said axis, wherein said selection is based on the result of said classification; computer program code for computing at least one root of each said quadratic curve with respect to said axis; computer program code for computing at least one intersection point on each said quadratic curve, where said intersection point is computed at a parameter value corresponding to said root; and computer program code for choosing a color determined by the spatial relationship between said intersection point and at least one said sample position.
