Abstract: Methods and apparatus associated with three-dimensional objects are described. In an example, a method comprises receiving data representing a three-dimensional model object, the data comprising object model data and object property data. For at least one object property, a sub-region of the object in which the object property is non-variable is identified and, for at least one location within the object, all sub-regions in which the location is situated are identified. Based on the combination of identified sub-regions for a location, print material data is determined for the location. Control data for the production of a three-dimensional object is generated according to the print material data.

Abstract: Methods and apparatus for three-dimensional object representation are described. In an example, data representing a three-dimensional object is received, the data comprising an object property description associated with each of a plurality of locations within the object. Distinct object property descriptions are identified and a data object, which has a plurality of addresses, is populated with data indicative of the distinct object property descriptions, such that data indicative of each distinct object property description is represented at a different address. Data comprising a representation of the object is generated, the data comprising a data object address associated with each of a plurality of locations, wherein the data object address corresponds to the address of data indicative of the object property description for that location.

Abstract: Methods and apparatus relating to substructures for 3D objects are described. In an example, a method for providing a three-dimensional halftone threshold matrix is described. The method may comprise receiving a substructure model representing a three-dimensional material structure and populating each location in the substructure model at which the structure exists with a halftone threshold value.

Abstract: A method is described in which data representing a three-dimensional object to be printed is obtained. The data comprises sub-volumes representing the three-dimensional object. A characteristic for the three-dimensional object to be printed is identified. Based on the identified characteristic, property data is set for individual sub-volumes to be used in printing the three-dimensional object. The identified characteristic is a function of the property data. The property data comprises material property data, structural property data and printing property 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: Certain examples described herein relate to a three-dimensional threshold matrix. The three-dimensional threshold matrix may be used for three-dimensional halftoning. In one example, values for a predefined two-dimensional threshold matrix are shifted with respect to a third dimension to provide the three-dimensional threshold matrix. In one example, the three-dimensional threshold matrix may then be processed in association with a digital representation of a three-dimensional object to output discrete material arrangement instructions for at least one production material. The instructions may be used to control an additive manufacturing system to produce the three-dimensional object.
