Abstract

A tool allows a user to create new designs for apparel and preview these designs in three dimensions before manufacture. Software and lasers are used in finishing apparel to produce a desired wear pattern or other design. Based on a laser input file with a pattern, a laser will burn the pattern onto apparel. With the tool, the user will be able to create, make changes, and view images of a design, in real time, before burning by a laser. The tool can be accessed or executes via a Web browser.

First claim

The invention claimed is:

1. A method comprising:
providing a garment design tool, accessible via a Web browser, that shows in a window of the Web browser of a three-dimensional preview image of a garment design as customized by a user with a finishing pattern;
in the garment design tool, providing an option for the user to select a garment base and upon the user's selection, showing in a window of the Web browser a first preview image of the selected garment template;
in the garment design tool, providing an option for the user to select a wear pattern from a menu of wear patterns and upon the user's selection, showing on a window of the Web browser a second preview image of the selected garment template with the selected wear pattern, wherein each wear pattern is associated with a laser input file to be used by a laser to produce that wear pattern onto a garment;
at a server, merging a laser input file associated with the selected wear pattern with an image of the selected garment template to generate a merged image, wherein the merged image is generated by
generating an adjusted base image from the image of the selected garment template without the selected wear pattern,
generating a pattern mask based on the laser input file associated with the selected wear pattern,
for a pixel at a pixel location of the merged image, obtaining a first contribution for the pixel location of the merged image by combining a first value for a pixel corresponding to the pixel location for the pattern mask and a pixel corresponding to the pixel location for the image of the selected garment template without the selected wear pattern,
for the pixel at the pixel location of the merged image, obtaining a second contribution at the pixel location for the merged image by combining a second value for a pixel corresponding to the pixel location for the pattern mask and a pixel corresponding to the pixel location for the adjusted base image,
combining the first contribution and second contribution to obtain a color value for a pixel at the pixel location for the second preview image, and
using the color value for the pixel at the pixel location in the merged image;
from the server, receiving the merged image to the Web browser, wherein the garment design tool shows the merged image as the second preview image; and
allowing the user to rotate the three-dimensional preview image of the garment design.

2. The method of claim 1 wherein the garment design comprises a design for at least one of a pair of pants, jeans, or shorts.

3. The method of claim 1 wherein the first contribution comprises a first percentage of the image of the selected garment template that passes to the merged image, and the second contribution comprises a second percentage of the adjusted base image that passes to the merged image.

4. The method of claim 1 wherein for the first contribution, the combining comprises a multiply operation of the first value for pixel corresponding to pixel location for the pattern mask and the pixel corresponding to the pixel location for the image of the selected garment template without the selected wear pattern.

5. The method of claim 1 wherein for the second contribution, the combining comprises a multiply operation of the second value for the pixel corresponding to the pixel location for the pattern mask and the pixel corresponding to the pixel location for the adjusted base image.

6. The method of claim 1 comprising:
saving the garment design as customized by a user with the selected garment template; and
based on the laser input file associated with the selected wear pattern, using a laser to create a finishing pattern on an outer surface of a target garment corresponding to the selected garment template.

7. The method of claim 1 comprising:
allowing the user to change a point from which the three-dimensional preview image of the garment design is viewed.

8. The method of claim 1 wherein the first contribution comprises a first percentage of the image of the selected garment template that passes to the merged image, and the second contribution comprises a second percentage of the adjusted base image that passes to the merged image.

9. The method of claim 1 wherein the merged image is received at the Web browser over an end-to-end encrypted channel.

10. The method of claim 1 comprising:
in the garment design tool, providing an option for the user to select a first level of wear or a second level of wear;
after the first level of wear is selected, showing via the Web browser a third preview image of the selected garment template with the first level of wear; and
after the second level of wear is selected, showing via the Web browser a fourth preview image of the selected garment template with the second level of wear.

11. The method of claim 10 wherein the second level of wear comprises a damage asset, comprising a hole or emerging hole, and the first level of wear does not comprise a damage asset.

12. The method of claim 1 wherein the generating a pattern mask based on the laser input file comprises:
generating an inverse image of the laser input file.

13. A method comprising:
providing a garment design tool, accessible via a Web browser, that shows in a window of the Web browser of a three-dimensional preview image of a garment design as customized by a user with a finishing pattern;
in the garment design tool, providing an option for the user to select a garment base and upon the user's selection, showing in a window of the Web browser a first preview image of the selected garment template;
in the garment design tool, providing an option for the user to select a wear pattern from a menu of wear patterns and upon the user's selection, showing on a window of the Web browser a second preview image of the selected garment template with the selected wear pattern, wherein each wear pattern is associated with a laser input file to be used by a laser to produce that wear pattern onto a garment;
at a server, merging a laser input file associated with the selected wear pattern with an image of the selected garment template to generate a merged image, wherein the merged image is generated by
generating an adjusted base image from the image of the selected garment template without the selected wear pattern,
generating a pattern mask based on the laser input file associated with the selected wear pattern, and the generating the pattern mask comprises generating an inverse image of the laser input file,
for a pixel at a pixel location of the merged image, obtaining a first contribution for the pixel location of the merged image by combining a first value for a pixel corresponding to the pixel location for the pattern mask and a pixel corresponding to the pixel location for the image of the selected garment template without the selected wear pattern,
for the pixel at the pixel location of the merged image, obtaining a second contribution at the pixel location for the merged image by combining a second value for a pixel corresponding to the pixel location for the pattern mask and a pixel corresponding to the pixel location for the adjusted base image,
combining the first contribution and second contribution to obtain a color value for a pixel at the pixel location for the second preview image, and
using the color value for the pixel at the pixel location in the merged image; and
from the server, receiving the merged image to the Web browser, wherein the garment design tool shows the merged image as the second preview image.

14. The method of claim 13 comprising:
allowing the user to change a point from which the three-dimens
