US 2018/0322612 A1 · COMPUTERIZED GENERATION OF ORNAMENTAL DESIGNS BY PLACING INSTANCES OF SIMPLE SHAPES IN ACCORDANCE WITH A DIRECTION GUIDE

Abstract

Systems and methods for computerized drawing of ornamental designs consisting of placed instances of simple shapes. The shapes, called elements, are selected from a small library of templates. The elements are deformed to flow along a direction field interpolated from user-supplied strokes, giving a sense of visual flow to the final composition, and constrained to lie within a container region. In an implementation, a vector field is computed based on user strokes. Streamlines that conform to the vector field are constructed, and an element is placed over each streamline. The shape of the elements may be modified such as by bending, stretching or enlarging to reduce spacing between elements and to minimize variations in spacing to improve aesthetic appearance.

Claims20

Dependent claims

A computerized method for generating two-dimensional ornamental designs comprising:

receiving one or more target containers, each represented by an associated simple closed curve which may form an irregular and asymmetrical shape;
receiving one or more ornamental elements;
receiving one or more direction guides corresponding to the target containers, the direction guides indicating desired directional flows of the ornamental elements;
and
placing, in accordance with directions indicated by the direction guides, the ornamental elements one or more times, in a non-overlapping manner, within boundaries of the target containers to generate an aesthetic arrangement of a plurality of placed ornamental elements.
