Abstract
Official abstract text for this publication.
A method for simulating a textured appearance on a uniform substrate includes using variable halftone dot orientations. A texture description is provided for generating electronic data representing a three-dimensional texture. Texture regions of the texture description are identified using pixel cells in the electronic data. Halftone dot orientations are assigned for each pixel cell based on a value of the pixel cell. The halftone dot orientation represents a recessed or a raised surface portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for simulating a texture on a uniform substrate, comprising: providing a first texture description for generating electronic data representing a three-dimensional texture, including: mapping the electronic data to an L*a*b* color space, determining a luminance value between 0 and 255 for each pixel cell, determining a difference between a maximum and a minimum luminance value for providing a partial dynamic range, enhancing the partial dynami…
