Abstract
Methods and apparatus relating to substructures for three-dimensional objects are described. In an example, a method comprises receiving a lattice model having a consistent dimensionality and determining a substructure model representing a three-dimensional material structure, the substructure model being based on the lattice model and specifying a variable material distribution. The substructure model may be populated with halftone threshold data to provide a three-dimensional halftone threshold matrix

A method comprising:
- receiving a lattice model having consistent dimensionality;
- determining a substructure model representing a three-dimensional material structure, the substructure model being based on the lattice model and specifying a variable material distribution;
- and
- populating the substructure model with halftone threshold data to provide a three-dimensional halftone threshold matrix.
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 print material coverage representation;
- a halftone module to provide halftone threshold data;
- a substructure module to define a substructure for a three-dimensional object to be generated, the substructure specifying in at least a region thereof a consistent lattice structure and a variable material distribution;
- wherein the apparatus is to apply a substructure and a halftoning to the print material coverage representation to generate control data for the production of a three-dimensional object having the substructure.
A method comprising:
- obtaining data representing a three-dimensional model object;
- mapping the data representing the three-dimensional model object to a print material coverage representation, the print material coverage representation specifying print materials to be applied at a location in the object;
- obtaining a substructure model representing a material structure, at least a portion thereof having a consistent lattice structure with a variable material distribution and being populated with halftone threshold values to provide a halftone threshold matrix;
- comparing the print material 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 material structure according to the substructure model.
