ABSTRACT:
Use of a non-manifold data structure enables retention of not only the interfaces between an entity in the process of being cut and a non-entity, but also the interfaces between entities or non-entities. These interfaces include the surfaces of substances (the boundaries between an entity and a non-entity) at intermediate points in time during a machining process represented by a series of Boolean operations, and the final or in-process interfaces obtained when machining (Boolean operations) is performed in a different sequence, and hence procedures following this method enable simulation to be retried at a low computation cost after a machining procedure is modified.
