Abstract: 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.

Abstract: 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.

Abstract: In one example in accordance with the present disclosure, an electronic system is described. The electronic system includes a scanning device to capture an image of an object. The object includes encoded data formed therein. An attribute determiner of the electronic system determines an actual value of a surface attribute of the object. The electronic system includes an extraction device to extract from the image of the object, a target value for the surface attribute from the encoded data. A comparator of the electronic system determines if a difference between the actual value and the target value has a specified value.

Abstract: In example implementations, an apparatus is provided. The apparatus includes a light table, a camera, and a processor. The light table is to hold an object. The camera is to capture images. The light table is positioned within a field of view of the camera. The processor is communicatively coupled to the camera to receive the images. The processor is to analyze the images to calculate an imaged transmission percentage at a plurality of different locations of the object based on a correlation function of the camera used to determine an amount of print agents to be dispense by a three dimensional printer to print the object.

Abstract: A device captures a digital image of a color of interest and a physical color calibration chart. A corrected color value of the color of interest is determined based on the physical color calibration chart and the color of interest as captured within the digital image. A selected color value for the corrected color value is determined, as a closest color value within a predetermined color space or as a spot color value within the predetermined color space.

Abstract: A target and a method to use the target to determine the translucence of media is disclosed. The target has a first region and a second region. The first region comprises a color chart. The second region comprises a test pattern that is covered by the sample media when the sample media is loaded onto the target. The test target has a first area and a second area, An image of the target loaded with the sample media is used to determine the translucence of the sample media. The color of the media over the first and second areas of the test target are matched to the nearest color patches in the image of the color chart. The estimated actual colors of the media over the first and second areas of the test target are determined using. the known colors of the nearest color patches. The translucence is determined using the difference between the estimated actual colors of the media over the first and second areas of the test target.

Abstract: 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.

Abstract: 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.
