1. A method comprising:
receiving, by a processor, object model data representing an object to be generated by an additive manufacturing apparatus;
determining, by the processor, an indication of a hollowness of the object;
determining, by the processor, a dimensional compensation value to apply to the object model data based on the indication of the hollowness of the object;
applying, by the processor, the dimensional compensation value to the object model data to generate modified object model data; and
causing, by the processor, the additive manufacturing apparatus to generate the object in accordance with the modified object model data.
