Abstract

Claims (64)

1. A method of displaying a pattern piece, comprising:

receiving a position of a second dart that provides a desired 3D contour in combination with a first dart included in the pattern piece that forms a garment through a user interface (UI);

setting an intersection point between a first extension line extending from the first dart and a second extension line extending from a center point of the second dart as a pivot point;

generating the second dart in the pattern piece based on a width of the first dart that is changed by rotating at least a portion of the pattern piece around the pivot point; and

displaying the pattern piece including the generated second dart through a display device,

wherein the generating of the second dart comprises:

generating a plurality of duplicate pattern pieces that divide at least a portion of the pattern piece based on the pivot point;

changing a width of the first dart by rotating one of the duplicate pattern pieces around the pivot point;

determining a width of the second dart based on the changed width of the first dart; and

generating, in the pattern piece, the second dart to which the determined width of the second dart is applied, and

wherein the changing of the width of the first dart comprises:

when one of the duplicate pattern pieces is rotated around the pivot point, detecting a position of a mouse changed based on the rotated duplicate pattern piece, and

determining the width or a length of the second dart based on a rotation angle obtained by the changed position of the mouse.

2. The method of claim 1 , wherein the generating of the duplicate pattern pieces comprises:

dividing the pattern piece into a first portion and a second portion defined by a first extension line in which a portion extending beyond the pivot point of the first extension line is removed and by the second extension line; and

generating the duplicate pattern pieces corresponding to the first portion and the second portion.

3. The method of claim 1 , further comprising at least one of:

determining a duplicate pattern piece to be rotated among the duplicate pattern pieces; and

determining a rotation direction of the determined duplicate pattern piece.

4. The method of claim 3 , wherein the changing of the width of the first dart comprises:

rotating the determined duplicate pattern piece around the pivot point in the determined rotation direction; and

wherein the width of the first dart is changed in proportion to an angle between both line segments of the first dart that is being changed by the rotating.

5. The method of claim 3 , wherein the determining of the width of the second dart comprises:

calculating a difference between the width of the first dart before being changed and the changed width of the first dart; and

determining the width of the second dart based on a ratio of the difference.

6. The method of claim 1 , further comprising:

determining a depth of the second dart corresponding to the position of the second dart,

wherein the generating of the second dart comprises:

generating the second dart in the pattern piece while maintaining the depth of the second dart.

7. The method of claim 1 , wherein the receiving of the position of the second dart comprises:

receiving a start point of the second dart on an outer line of the pattern piece on which the first dart is displayed.

8. The method of claim 7 , wherein the setting as the pivot point comprises:

generating the first extension line of a center line of the first dart that passes through a vertex of the first dart; and

generating the second extension line extending in a normal direction from the start point of the second dart.

9. The method of claim 1 , further comprising:

receiving a depth of the second dart corresponding to the position of the second dart.

10. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the method of claim 1 .

11. An apparatus for displaying a pattern piece, comprising:

a user interface (UI) configured to receive a position of a second dart that provides a desired 3D contour in combination with a first dart included in the pattern piece that forms a garment;

a processor configured to set an intersection point between a first extension line extending from the first dart and a second extension line extending from a center point of the second dart as a pivot point, and generate the second dart in the pattern piece based on a width of the first dart that is changed by rotating at least a portion of the pattern piece around the set pivot point; and

an output device configured to display the pattern piece including the second dart,

wherein the processor is configured to:

generate a plurality of duplicate pattern pieces that divide at least a portion of the pattern piece based on the pivot point;

change a width of the first dart by rotating one of the duplicate pattern pieces around the pivot point;

determine a width of the second dart based on the changed width of the first dart; and

generate the second dart in the pattern piece to which the determined width of the second dart is applied, and

wherein the processor is configured to change the width of the first dart by:

when one of the duplicate pattern pieces is rotated around the pivot point, detecting a position of a mouse changed based on the rotated duplicate pattern piece, and

determining the width or a length of the second dart based on a rotation angle obtained by the changed position of the mouse.

12. The apparatus of claim 11 , wherein the processor is configured to:

divide the pattern piece into a first portion and a second portion defined by the first extension line, in which a portion extending beyond the pivot point of the first extension line is removed, and by the second extension line; and

generate the duplicate pattern pieces corresponding to the first portion and the second portion.

13. The apparatus of claim 11 , wherein the processor is configured to:

determine a duplicate pattern piece to be rotated among the duplicate pattern pieces; and

determine a rotation direction of the determined duplicate pattern piece.

14. The apparatus of claim 13 , wherein the processor is configured to:

rotate the determined duplicate pattern piece around the pivot point in the determined rotation direction; and

change the width of the first dart in proportion to an angle between both line segments of the first dart that is changed by the rotating.

15. The apparatus of claim 13 , wherein the processor is configured to:

calculate a difference between the width of the first dart before being changed and the changed width of the first dart; and

determine the width of the second dart based on a ratio of the difference.

16. The apparatus of claim 11 , wherein the processor is configured to:

determine a depth of the second dart corresponding to the position of the second dart; and

generate the second dart in the pattern piece while maintaining the determined depth of the second dart.
