Designated region projection printing

An apparatus for performing object-design for a three-dimensional object, the apparatus comprising:

• a memory storing instructions;
• and
• a processor in communication with the memory, wherein, when the processor executes the instructions, the processor is configured to cause the apparatus to perform:
• obtaining a plurality of discrete surfaces of a three-dimensional object,
• obtaining a plurality of spatial patterns for the plurality of discrete surfaces,
• projecting the plurality of spatial patterns into a two-dimensional plane to obtain a plurality of flattened patterns, and
• outputting the plurality of flattened patterns as an object-design result for the three-dimensional object.

A non-transitory computer-readable storage medium, storing computer-readable instructions, wherein, the computer-readable instructions, when executed by a processor, are configured to cause the processor to perform:

• obtaining a plurality of discrete surfaces of a three-dimensional object;
• obtaining a plurality of spatial patterns for the plurality of discrete surfaces;
• projecting the plurality of spatial patterns into a two-dimensional plane to obtain a plurality of flattened patterns;
• and
• outputting the plurality of flattened patterns as an object-design result for the three-dimensional object.
