## Abstract

A three-dimensional object data generation apparatus includes an attribute setting unit that sets, for each of plural voxels representing a three-dimensional object, an attribute of a voxel of a second three-dimensional object, which is obtained by combining plural first three-dimensional objects together, in accordance with a priority level set for an attribute of a voxel at a time when the plural first three-dimensional objects are combined together.

## Claims

### Claim 1

A three-dimensional object data generation apparatus comprising:
a processor programmed to function as:
an attribute setting unit that sets, for each of a plurality of voxels representing a three-dimensional object, an attribute of a voxel of a second three-dimensional object, which is obtained by combining a plurality of first three-dimensional objects together, in accordance with a priority level set for an attribute of a voxel at a time when the plurality of first three-dimensional objects are combined together.

### Claim 2 (depends on 1)

The three-dimensional object data generation apparatus according to claim 1,
wherein the attribute setting unit sets an attribute having a higher priority level for a voxel in an overlap between the plurality of first three-dimensional objects.

### Claim 3 (depends on 2)

The three-dimensional object data generation apparatus according to claim 2, wherein the processor is further programmed to function as:
a first priority level setting unit that sets the priority level set in the overlap for at least one of voxels outside the overlap.

### Claim 4 (depends on 2)

The three-dimensional object data generation apparatus according to claim 2,
wherein the attribute setting unit sets, for a voxel located at a boundary between the overlap and a part other than the overlap, an intermediate attribute between attributes set for voxels facing each other across the boundary.

### Claim 5 (depends on 1)

The three-dimensional object data generation apparatus according to claim 1, wherein the processor is further programmed to function as:
a second priority level setting unit that sets the priority level for a virtual voxel set in a hollow part of the first three-dimensional objects.

### Claim 6 (depends on 1)

The three-dimensional object data generation apparatus according to claim 1,
wherein the attribute setting unit sets a material having adhesiveness as an attribute for a voxel located at a boundary between the plurality of first three-dimensional objects.

### Claim 7

A three-dimensional object forming apparatus comprising:
a forming unit that forms a three-dimensional object on a basis of three-dimensional object data generated by a three-dimensional object data generation apparatus, the three-dimensional object data generation apparatus comprising an attribute setting unit that sets, for each of a plurality of voxels representing a three-dimensional object, an attribute of a voxel of a second three-dimensional object, which is obtained by combining a plurality of first three-dimensional objects together, in accordance with a priority level set for an attribute of a voxel at a time when the plurality of first three-dimensional objects are combined together.

### Claim 8

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising setting, for each of a plurality of voxels representing a three-dimensional object, an attribute of a voxel of a second three-dimensional object, which is obtained by combining a plurality of first three-dimensional objects together, in accordance with a priority level set for an attribute of a voxel at a time when the plurality of first three-dimensional objects are combined together.
