摘要:
The present invention is 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. The medial axis of the polygon is determined, concentric polygons are then constructed 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.

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 medial axis 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.

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.

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.

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.
摘要:
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.

An interactive system and method for creating and modifying embroidery designs is disclosed. The system provides a user with numerous functions for interactively creating and modifying embroidery designs, and generating the necessary stitch commands for recreating the embroidery design on an embroidery stitching machine. The system is preferably operative on an IBM PC. The system is menu-based, and may be used for modifying embroidery designs in either outline-format or stitch-format. Once a design has been entered, the user may utilize predetermined functions to quickly alter a design and visualize the resulting design. The system further provides a method for modifying embroidery designs in an outline format into bridge type lettering.

This invention relates to a method for converting low-level stitch-by-stitch numerical control code embroidery design programs into an outline format which can be edited and modified to generate new design patterns which may be converted back to either stitch-by-stitch numerical control codes or a condensed data format. The invention permits a user to independently vary and modify a large variety of characteristics of an existing embroidery design control program including converting straight line portions of a design pattern to smoothed curves, converting a portion or all of the stitching in a design from one type of stitching, such as satin, bean or tatami, to a different type of stitching, changing stitch lengths in any fill patterns or stitch runs, changing the fill patterns in any fill stitches, adding or deleting automatic underlay stitching, changing the density of stitching in any portion of a design, moving or deleting any portion or point, copying, rotating, scaling, and mirroring any portion of a design, correcting satin segment points which are reversed, changing fill angles, changing the order of sewing segments, and changing the color of any portion of a design.
