Abstract: Techniques for dynamically subdividing a 3D mesh to enhance texture and color reproduction are provided. In embodiments, a high-resolution image of an object is received, where the high-resolution image is mapped to a 3D mesh of the object. The high-resolution image has a higher resolution than the 3D mesh. Degrees of color variation in the high-resolution image are detected. Weights are calculated for areas of the 3D mesh based on the degrees of color variation in the high-resolution image. One or more of the areas of the 3D mesh is subdivided based on the calculated weights. Color values from the high-resolution image are then assigned to the 3D mesh.

Abstract: Local color information in a 3D mesh is used to enhance fine geometric features such as those in embroidered clothes for 3D printing. In some implementations, vertex color information is used to detect edges and to enhance geometry. In one embodiment, a 3D model is projected into a 2D space to obtain a 2D image, so that pixels that lie on edges in the 2D image can be detected. Further, such edge information is propagated back to the 3D model to enhance the geometry of the 3D model. Other embodiments may be described and/or claimed.

Abstract: Methods and systems for correcting depth irregularities in a three-dimensional scanned model. In particular, one or more embodiments obtain depth data and color data for an object using a depth scanner and a color scanner, respectively. One or more embodiments identify, based on edge information in the color data, regions that have no depth data that are part of the object. One or more embodiments then correct the depth frame by assigning depth data to the identified regions based on a gradient of depth data from areas near the identified regions. The methods and systems use the corrected depth data to generate a corrected three-dimensional model of the object.

Abstract: Cutout object merge techniques are described. In one or more embodiments, a cutout object is identified for insertion into a scene. The cutout object may, for instance, be selected from a library of cutout objects, each of which was extracted from an already-captured image. Before capturing an image of the scene, the selected cutout object may be placed in a substantially real-time display of the scene, such as that which is displayed via a camera's view finder. Using an image capturing device, an image of the scene may then be captured. Once an image of the scene is captured, the cutout object and the captured image may be merged to form a composite image that includes the cutout object at a location in the scene specified by the placement.

Abstract: Techniques are disclosed for converting a stereolithographic model into an STL data file that defines logically related components and subcomponents of an object. A user can categorize elements of an object to form logically related components and subcomponents of the object. Each element is represented by a triangle. All triangles representing each of these components and subcomponents are then reordered and listed sequentially within the STL. Each list is delimited at the beginning and end by two hidden triangles, one or both of which store unique identification values that are associated with the respective individual components. Additionally, a reference table can be added to the STL. The reference table includes instructions, operations or other information that is specifically associated with each component and subcomponent using the unique identification values. These instructions and operations enable users to have better control over 3D print quality than is possible using existing techniques.

Abstract: A method includes requesting a lock on a resource. The request for the lock on the resource is specified as a low priority non-blocking request that does not block one or more other requests such that one or more other requests can request a lock on the resource and obtain the lock on the resource in priority to the low priority non-blocking request. Based on the low priority request, the method includes maintaining the low priority request in a non-blocking fashion until a predetermined condition occurs. As a result of the predetermined condition occurring, the method includes handling the low priority request such that it is no longer treated as a low priority non-blocking request. Embodiments may further include a kill request which kills any operations on the resource, aborts any transactions having a lock on the resource, and locks the resource.

Abstract: This document describes techniques for contextualization and enhancement of textual content. In one or more implementations, textual content is analyzed to determine whether the textual content is appropriate for an intended context. The intended context corresponds to an intended mood, emotion, tone, or sentiment of the textual content. If it is determined that the textual content does not conform to the intended context, suggestions are generated to modify the textual content to conform to the intended context.
