Abstract: Examples of methods for generating supports are described herein. In some examples, a method includes determining a starting position from a set of voxels of a three-dimensional (3D) object model to be additively manufactured. In some examples, the method also includes generating a support for the 3D object model by traversing a cost field from the starting position.

Abstract: An example of an apparatus is provided. The apparatus includes an input device to receive design data. The design data includes information about a geometry and load characteristics of an object. The apparatus further includes a structural design engine to generate print data to print the object on a three-dimensional printer based on the design data. The apparatus also includes a fluid design engine to generate fluidic data. The fluidic data represents a fluid channel within the object. In addition, the apparatus includes an output engine to generate an output file based on the print data and the fluidic data

Abstract: Methods and apparatus relating to three-dimensional object models are described. In one example, (i) data representing a geometrical description of a three-dimensional object defining object geometry in a geometric space and (ii) at least one object property description describing an object property in an object property space are received. The object property space and the geometric space are intersected to define an object model, wherein an object property is defined at an intersection between a described object property and defined object geometry.

Abstract: Examples disclosed herein relate to a likelihood of success of a remote document service. For example, a processor may determine to transmit information about a remote document service to a device based on a likelihood of success associated with the ability of the device to perform the remote document service. The likelihood of success may be based on the performance history of the device and a factor associated with performance history and likelihood of success

Abstract: Examples of methods for object group packings are described herein. In some examples, a method includes ordering objects of a chromosome into a first group and a second group in accordance with a first priority and a second priority. In some examples, the method includes determining, using a genetic procedure in accordance with the first priority and the second priority, a first arrangement within the first group and a second arrangement within the second group to produce a packing in a volume.

Abstract: Examples of methods for point cloud alignment are described herein. In some examples, a method includes orienting a model point cloud or a scanned point cloud based on a set of initial orientations. In some examples, the method includes determining, using a first portion of a machine learning model, first features of the model point cloud and second features of the scanned point cloud. In some examples, the method includes determining, using a second portion of the machine learning model, correspondence scores between the first features and the second features based on the set of initial orientations. In some examples, the method includes globally aligning the model point cloud and the scanned point cloud based on the correspondence scores.

Abstract: Examples of methods for registering objects are described herein. In some examples, a method includes determining a set of overlap scores based on a set of orientations between a first bounding box of a three-dimensional (3D) object model and a second bounding box of a 3D scan of an object. In some examples, the method includes registering the 3D scan with the 3D object model based on the set of overlap scores.
