Computerized generation of ornamental designs by placing instances of simple shapes in accordance with a directional hint

摘要

Systems and methods for computerized drawing of ornamental designs consisting of placed instances of simple shapes. The forms, which are called elements, are selected from a small library of templates. The elements are deformed to flow along a directional field that is interleaved from strokes given by a user to give an impression of visual flow to the final composition, and are constrained to lie within a container area. In one implementation, a vector field is calculated based on user strokes. Streamlines are created that match the vector field, and an element is placed over each streamline. The shape of the elements may be modified, for example by bending, stretching or enlarging, to reduce spacing between elements and minimize variations in pitch to enhance the aesthetic appearance.
