The present invention is an improved method for automatically generating chenille filled embroidery stitch patterns and/or claim stitching in a computer aided design system in which the shape to be filled is a complex polygon. Concentric polygons are constructed, such as either by using the medial axis of the polygon or by constructing offset elements and joining arcs without use of the medial axis, and sorted, and spirals are placed along the polygons with stitches being placed along the spirals. For chain stitching, rather than placing spirals, the chain stitches are placed on the perimeter of the concentric polygons.

Method for automatically generating a chenille filled emproidery stitch

The present invention is an improved method for automatically generating chain stitching in a computer aided design system in which the shape to be filled is a complex polygon. The Voronoi Diagram of the polygon is determined, concentric polygons are then constructed and sorted and the chain stitches are placed on the perimeter of the concentric polygons. The chain stitches can be used to completely fill a stitch pattern, such as an embroidery stitch pattern, or in conjunction with other stitching, such as Chenille stitching in an embroidery pattern.

Method for automatically generating chain stitches

An improved method for automatically generating chenille filled embroidery stitch patterns and/or chain stitching in a computer aided design system in which the shape to be filled is a complex polygon. A spine of a medial axis of the Voronoi Diagram of the polygon is determined, modified concentric polygons are then constructed by clipping the edges of the concentric polygons that are within a clip width of the spine, the modified concentric polygons are then sorted and spirals are placed along the modified polygons with stitches being placed along the spirals, with the occurrence of any bald spots in the shape being filled being minimized. For chain stitching, rather than placing spirals, the chain stitches are placed on the perimeter of the concentric polygons.

A method for creating a self-generating embroidery design pattern, which may be provided alone or merged with an existing pattern comprising the steps of defining a predetermined fractal shape having an associated axiom and production rules; parsing the axiom and production rules associated with the defined fractal shape and performing the production rules a selectable predetermined number of times for providing a plurality of stitch or outline points in accordance with a desired finished embroidery design pattern size, the stitch points being in either an outline data format or a stitch data format; converting the outline data format into a stitch data format; and translating the stitch data format into a predetermined embroidery language machine code for controlling an associated embroidery machine responsive to the predetermined embroidery language machine code.
