Abstract
Official abstract text for this publication.
A three-dimensional relief can be produced from one or more two-dimensional digital (2D) images. A height field is computed from the one or more 2D images and illumination direction information. The height field comprises a multiplicity of geometric surface elements arrayed in a 2D field corresponding to the pixels of the one or more 2D images. Each geometric surface element corresponds to a pixel of each of the digital images and has at least one height parameter representing a displacement from a surface floor. Once the height field is computed, optimizations or adjustments can optionally be made to the height field. The height field can be used to fabricate relief elements in a material, such that each relief element corresponds in shape, position in the height field, and height above the surface floor, to one of the geometric surface elements in the height field.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer implemented method for producing a three-dimensional relief from at least one two-dimensional digital (2D) image, the method being implemented in a computer system comprising one or more processors and a computer-controlled fabrication system, the method comprising the steps of: computing, using the one or more processors, a height field from a first 2D digital image and a second 2D digital image and illumination direction information, the height…
