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.

A processing apparatus, comprising:
- an interface to receive:
- request information for a three-dimensional (3D) object to be generated, wherein the request information includes a size and shape of the 3D object to be generated;
- and
- a substructure model for a 3D material structure, wherein substructure is a mesh-like structure having some physical space occupied by the material structure and some unoccupied, empty space;
- a processor;
- and
- a memory storing instructions that are executable to cause the processor to:
- generate a rasterized representation of the substructure model for the 3D material structure, the rasterized representation comprising a plurality of parallel planes, each plane including a binary bitmap, wherein each value in the binary bitmap of each plane indicates either the unoccupied, empty space of the 3D material structure or a discrete location of the physical space where the 3D material structure exists;
- populate each of the discrete locations of each of the plurality of parallel planes where the 3D material structure exists with a halftone threshold to generate a 3D halftone threshold matrix;
- apply the request information, including the size and shape, of the 3D object to the 3D halftone threshold matrix to generate control data, wherein the control data is for controlling a manufacturing of the 3D object;
- and
- cause the 3D object to be generated based on the control data.
