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.
Claims15
Processing apparatus, comprising:
- an interface to receive data representing a three-dimensional model object, the data comprising object model data and object property data;
- a mapping module to map received data to a volume coverage representation relating to object property data at a given location;
- a halftone module to provide halftoning threshold data;
- a substructure module to define a substructure for a three dimensional object to be generated;
- wherein the apparatus is to apply a substructure and a halftoning to the volume coverage representation to generate control data for the production of a three-dimensional object having the substructure.

A method comprising:
- obtaining a three-dimensional bit-map comprising a M×N×L array of voxels representing a three dimensional model object, each voxel being located at a unique three-dimensional location;
- mapping each voxel representing the three dimensional model object to a volume coverage representation, the volume coverage representation specifying print materials as proportions of a set of available print materials at a location;
- obtaining a substructure model comprising an M×N×L array of voxels representing a material structure and populated with halftone threshold values to provide a halftone threshold matrix;
- comparing the volume coverage representation with threshold values of the threshold matrix representing the same three-dimensional location to generate control data for generating a three-dimensional object having a substructure according to the substructure model.
