Abstract: Methods and apparatus for three-dimensional object representation are described. In an example, data representing a three-dimensional object is received, the data comprising an object property description associated with each of a plurality of locations within the object. Distinct object property descriptions are identified and a data object, which has a plurality of addresses, is populated with data indicative of the distinct object property descriptions, such that data indicative of each distinct object property description is represented at a different address. Data comprising a representation of the object is generated, the data comprising a data object address associated with each of a plurality of locations, wherein the data object address corresponds to the address of data indicative of the object property description for that location.

Abstract: Methods and apparatus relating to substructures for 3D objects are described. In an example, a method for providing a three-dimensional halftone threshold matrix is described. The method may comprise receiving a substructure model representing a three-dimensional material structure and populating each location in the substructure model at which the structure exists with a halftone threshold value.

Abstract: A method of embedding data in a printed output having at least two-dimensions is described in which content data for the printed output and data to be embedded in the printed output are obtained. An input property value for a content element from the content data is determined. This is used to determine an output value for a probabilistic distribution of a set of output material compositions for a spatial element of the printed output, corresponding to the content element, based on the data to be embedded and the input property value.

Abstract: A pixel source for a visual presentation is disclosed. The pixel source can include a light source, a large gamut pixel, a subtractive mask, and a control input to control the subtractive mask. A display device is also disclosed comprising a light source array with a large gamut pixel array and subtractive mask array disposed thereon. In operation, wide-band light emitted from each light source can be modulated by each large gamut pixel to output a plurality of primary colors. Each subtractive mask can be controlled to block, partially transmit, or fully transmit any number of the outputted primary colors to produce color points that can be interpolated and half-toned to output a large gamut of secondaries for each pixel.
Abstract translation: 公开了用于视觉呈现的像素源。 像素源可以包括光源，大色域像素，减影掩模和用于控制减影掩模的控制输入。 还公开了一种显示装置，其包括具有设置在其上的大色域像素阵列和减影掩模阵列的光源阵列。 在操作中，从每个光源发射的宽带光可以被每个大色域像素调制以输出多个原色。 可以控制每个减法掩模以阻挡，部分传输或完全传输任何数量的输出原色，以产生可被内插和半色调以便为每个像素输出大色域的二次色系的色点。

Abstract: An example computer-implemented method of generating a pattern of thresholds for halftone printing of an image is disclosed. The halftone pattern is generated by an analytical computation of threshold values in-situ using a quasicrystal function. Each halftone pattern produced is non-periodic yet possesses ordered character where the pattern does not line up perfectly with a shifted copy of itself. The generation of such halftone patterns is suited to applications where a single halftone threshold value may be used per pixel.
Abstract translation: 公开了一种生成图像半色调打印阈值模式的计算机实现方法。 半色调图案通过使用准晶体功能原位的阈值的分析计算产生。 所生产的每个半色调图案都是非周期性的，并且具有排序的字符，其中图案与其自身的偏移副本完全不一致。 这种半色调图案的产生适合于每个像素可以使用单个半色调阈值的应用。

Abstract: A method for generating a print mapping and a method for image processing are described. The print mapping comprises obtaining spectral characteristics for printing fluids and determining reflectance values for computing a gamut in spectral space. The gamut provides a mapping of reflectance to Neugebauer Primary area coverages for a printing device.
