1. A method for forming a desired layer representation of a three-dimensional object from initial layer representations of the three-dimensional object, for use in forming the object on a layer-by-layer basis, comprising:

  • supplying an initial layer representation of a first layer of the object;

    supplying an initial layer representation of a second layer of the object, the second layer being spaced above the first layer;

    forming a desired layer representation for a first selected one of the first and second layers, including performing a Boolean operation between the initial layer representation of the first selected one and the initial layer representation of a second selected one of the first and second layers, the second selected one being different from the first selected one; and

    supplying the desired layer representation for use in forming the first selected one of the first and second layers of the three-dimensional object.
