Abstract
A method generates a distance field of an object, where the distance field includes a set of cells and the object includes a set of stylized strokes. Each stylized stroke includes a centerline, a set of profiles, and a set of terminals. A processor is included for performing steps of the method. A first cell of the set of cells enclosing the object is determined. An outside reconstruction method is associated with the first cell. For each stylized stroke, centerline cells of the set of cells are determined, where each centerline cell encloses a portion of the centerline of the stylized stroke. A centerline reconstruction method is associated with each centerline cell. For each terminal of each stylized stroke a terminal distance field is generated, the terminal distance field including a terminal reconstruction method. Reconstructed distances are determined using the reconstruction methods to generate the distance field of the object.
