논문 초록 (Abstract)
The requirements of multi-resolution models of feature-based solids, which represent an object at many levels of feature detail, are increasing for engineering purposes, such as analysis, network-based collaborative design, virtual prototyping and manufacturing To provide multi-resolution models for various applications, it is essential to generate adequate solid models at varying levels of detail (LOD) after feature reanangement, based on the LOD criteria However, the non-commutative property of the union and subtraction Boolean operations is a severe obstacle to arbitrary feature rearrangement To solve this problem we propose history-based Boolean operations that satisfy the commutative law between union and subtraction operations by considering the history of the Boolean operations Because these operations guarantee the same resulting shape as the original and reasonable shapes at the intermediate LODs for an arbitrary rearrangement of its features, various LOD criteria can be applied for milti-resolution modeling in different applications
