Systems and methods are described herein relating to compositing dynamic content on 3D printed objects. A printing subsystem may transmit printing instructions to a 3D printer that include only a single digital mesh of the object, digital meshes of each discrete element of the dynamic content, and instructions for compositing unique combinations of the discrete elements on each instance of the object or each instance of a set of objects printed by the 3D printer.

Dynamic element compositing

Systems and methods are described herein to determine positive or negative displacement distances for each pixel of an image of a graphical element. A displacement subsystem may determine surface displacement distances based on a function of a distance of each pixel to a nearest edge pixel of the image of the graphical element. A mapping subsystem may generate a surface displacement map of the graphical element to be applied to a surface of a three-dimensional object. The surface displacement map may be used to generate a mesh file and/or transmitted to a three-dimensional printing for printing on a surface of an object.

Graphical element surface displacements based on distance functions

The present disclosure pertains to systems and methods for mapping an image to a three-dimensional pattern of relief features on a surface of an object for 3D printing. In some examples, a system may determine a pattern of relief features, including debossed relief features and/or embossed relief features, to create a shading pattern on the surface of 3D printed object that approximates the continuous halftones of an image.

Color surface formation by single-color 3D printing

According to examples, an apparatus may include a processor and a non-transitory computer readable medium on which is stored instructions that the processor may execute to determine displacement levels of multiple locations of an image and to select a sampling density for the multiple locations. The processor may execute the instructions to generate an array of points according to the selected sampling density, the array of points identifying displaced portions of the image.

Generation of points identifying displaced portions of an image

A computing system for adaptive point generation includes a storage to store a densely sampled polyline or surface, or mathematical function, and a processor to compute the area of a contour of the polyline or function with respect to itself, or compute the volume of the surface or function with respect to itself, adaptively resample the polyline, surface, or function, wherein the adaptive resampling is based on and inversely proportional to the computed area or volume, and connect adaptively resampled points as an adaptively sampled polyline or surface.

Adaptive point generation

An example device includes at least one three-dimensional (3D) printed tablet and a 3D-printed production support structure. Each 3D-printed tablet includes an excipient material and an active ingredient. The 3D-printed support structure includes a 3D-printed planar structure comprising the excipient material and at least one 3D-printed connecting member comprising the excipient material. The planar structure includes at least one aperture, each aperture corresponding to one of the at least one 3D-printed tablet. The connecting member detachably connects the at least one 3D-printed tablet with the 3D-printed planar structure and positions the at least one 3D-printed tablets within the apertures.

Printed support structure

Examples analyze three-dimensional printing specifications associated with a three-dimensional printing device to determine test angles for a test object and test surfaces corresponding to the test angles for the test object. Examples generate the test object for color calibration for the three-dimensional printing device based at least in part on the test angles and test surfaces that are configured with at least one test color.

Color calibration for three-dimensional printing

In one example in accordance with the present disclosure a three-dimensional illumination chart is described. The chart includes a substrate divided into a number of portions. Each portion includes a raised relief pattern disposed thereon having a relief angle relative to a reference line. Each relief angle of the raised relief patterns of the number of portions is different from other relief angles of other raised relief patterns of other of the number of portions.

Determining illumination direction with three-dimensional illumination charts

Examples relate to providing spatial analysis using attribute graphs. In one examples, there are a number of spatial points that each represent characteristics in a dimensional space. Non-data points are generated in the dimensional space, and a Delaunay triangulation is performed using the spatial points and the non-data points to generate a plurality of edges, where interior points of the plurality of non-data points that are in an interior space of the plurality of spatial points are excluded from the Delaunay triangulation. Next, spatial edges from the plurality of edges that each connect a spatial point that is connected to a first mixed edge to another spatial point that is connected to a second mixed edge are identified, where the spatial edges are used to generate a robust contour of a cluster of the spatial points.

Spatial analysis with attribute graphs

A system including a memory to store instructions and initial color representations and a processor to execute the instructions in the memory to reference a database having a set of lexical color classifiers, transform each of at least a pair of initial color representations to color values associated with the set of lexical color classifiers, and generate a relative similarity measure related to the at least a pair of initial color representations based on the color values associated with the set of lexical color classifiers.

Generating color similarity measures

Examples disclosed herein relate to determining the shape of an object representation. In one implementation, a processor determines contours of a silhouette of an object representation above a contour degree threshold, where a contour degree is determined based on the area of the contour with respect to itself. The processor may identify a shape type of the object representation based on a comparison of the determined contours to shape definition information.

Determine the shape of a representation of an object

A corrected optical property value of an optical property of interest captured within a digital image is determined. A search query based on the corrected optical property value is determined. A database is searched using the search query to determine search results for the search query that have appearance attributes with optical properties at least similar to the corrected optical property value.

Corrected optical property value-based search query

An identification mark may have a calibration color, a predetermined authentication color, and a predetermined difference between the calibration color and the predetermined authentication color that is associated with a product; and a visual code with a mechanism that identifies the predetermined difference.

Identification mark with a predetermined color difference

An apparatus for backing up a digitally stored image includes a substrate on which the image and digital restoration data corresponding to the digitally stored image are printed on the substrate. The apparatus may be scanned to restore the image printed thereon to its original digital form.

Analog backup of digital images and image restoration therefrom

A method for producing a customized print includes determining a color of at least one feature of an object, where the object is imaged with a reference color chart. A color palette is selected based on the at least one determined feature color and a print is generated based on the selected color palette. A system for producing a customized print is also described.
