Halftoning of object data for a three-dimensional object
First Claim
1. A method of processing object data for an apparatus, the apparatus being arranged to produce a three-dimensional object, the method comprising:
- receiving object data for a three-dimensional object;
processing the object data to determine first data corresponding to a first portion of the three-dimensional object and second data corresponding to a second portion of the three-dimensional object separate from the first portion of the three-dimensional object, the first portion corresponding to a shell portion of the three-dimensional object and the second portion corresponding to a core portion of the three-dimensional object;
halftoning the first data using a first halftoning technique to generate control instructions for the apparatus to produce the shell portion; and
halftoning the second data using a second halftoning technique to generate control instructions for the apparatus to produce the core portion, the second halftoning technique being different from the first halftoning technique.

Abstract
Certain examples described herein relate to the processing of object data corresponding to a three-dimensional object. First data corresponding to a first portion of the three-dimensional object and second data corresponding to a second portion of the three-dimensional object, separate from the first portion, are determined. The first data is halftoned using a first halftoning technique to generate control instructions for an apparatus to produce the first portion of the three-dimensional object. The second data is halftoned using a second halftoning technique to generate control instructions for the apparatus to produce the second portion of the three-dimensional object.

8. An apparatus arranged to generate control data for production of a three-dimensional object comprising:
-
a data interface to receive object data representative of a three-dimensional object; an object data processor arranged to process the object data to determine first data corresponding to a first portion of the three-dimensional object and second data corresponding to a second portion of the three-dimensional object separate from the first portion; and a first halftoner arranged to process the first data using a first halftoning technique to generate control instructions for the apparatus to produce the first portion of the three-dimensional object; and a second halftoner arranged to process the second data using a second halftoning technique to generate control instructions for the apparatus to produce the second portion of the three-dimensional object. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A non-transitory computer-readable storage medium comprising a set of computer-readable instructions stored thereon, which, when executed by a processor, cause the processor to:
-
process object data corresponding to a three-dimensional object to determine first data corresponding to a first portion of the three-dimensional object and second data corresponding to a second portion of the three-dimensional object separate from the first portion, the first portion corresponding to a shell portion of the three-dimensional object and the second portion corresponding to a core portion of the three-dimensional object; halftone the first data using an error diffusing halftoning technique to generate control instructions for an apparatus to produce the first portion of the three-dimensional object; and halftone the second data using matrix halftoning to generate control instructions for the apparatus to produce the second portion of the three-dimensional object.
