EMBROIDERY IMAGE RENDERING USING PARAMETRIC TEXTURE MAPPING

摘要

Rendering methods, systems, and computer-readable media for rendering a simulated embroidery design image based on an embroidery design are presented. Given an embroidery design comprising a plurality of stitch representations and a lighting angle for the simulated embroidery design image, embodiments process the stitch representations to determine a stitch length and lighting angle and select from a stitch image database a stitch image corresponding to the stitch length and lighting angle, and place the selected stitch on a rendering canvas in a position corresponding to the stitch position indicated by the stitch representation. When rendered, all of individual stitch image on the rendering canvas appear to be illuminated from the same direction.
