Spot aware print workflow techniques and system are described. In an implementation, a digital document is received for printing that includes a plurality of objects. Spot functionality is detected as corresponding to a respective object based on object properties detected for the respective object. One or more spot planes for are generated based on the spot functionality and a determination is made of color values for the one or more spot planes, respectively, based on context data describing a context, in which, the one or more spot planes are to be printed. The spot planes having the color values are output for printing by a print mechanism.

Systems and methods are disclosed for generating viewpoints and/or digital images of defects in a three-dimensional model. In particular, in one or more embodiments, the disclosed systems and methods generate exterior viewpoints by clustering intersection points between a bounding sphere and rays originating from exterior vertices corresponding to one or more defects. In addition, in one or more embodiments, the disclosed systems and methods generate interior viewpoints by clustering intersection points between one or more medial spheres and rays originating from vertices corresponding to interior vertices corresponding to one or more defects. Furthermore, the disclosed systems and methods can apply colors to vertices corresponding to defects in the three-dimensional model such that adjacent vertices in the three-dimensional model have different colors and are more readily discernable.

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.

Color-based geometric feature enhancement for 3D models

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.

Color-based dynamic sub-division to generate 3D mesh

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.

The present disclosure is directed toward systems and methods for providing a preview that includes a visualization of various properties of an object to be printed from a three-dimensional input model. For example, systems and methods described herein involve performing one or more of a printability analysis, appearance analysis, true-visual analysis, accuracy analysis, and an integrity analysis to identify defects, visual characteristics and other properties of the object to be printed. Systems and methods described herein further relate to generating texture maps and applying the texture maps to three-dimensional renderings of the three-dimensional model to provide an interactive preview to enable a user to view and comprehend various issues associated with printing the object from the three-dimensional model.

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.

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.

Conversion of stereolithographic model into logical subcomponents

A PDF document is repurposed to save paper and ink. Preprocessing is performed on the PDF document. The PDF document has a first quantity of pages of content and a first quantity of ink. Further, complexity analysis is performed on the PDF document. In addition, a document object model based on the PDF document is created. In addition, content re-layout is performed on the PDF document based on the content repurposing such that a printer prints the PDF document with the content in a transformed format that results in a second quantity of pages being printed without falling below a predetermined readability threshold and a second quantity of ink being utilized. The second quantity of pages is less than the first quantity of pages. The second quantity of ink is less than the first quantity of ink.
