Résumé: Natural and manufactured objects are usually layered. For example, a human thigh has layers of skin and bone, among others; architectural buildings have walls of exterior sheeting, insulation, and interior finishing. By modeling each layer with a sheet of cuboids, the thickness property that is inherent in many objects is preserved. In addition, modeling layers with cuboids simplifies the making of virtual holes in external layers to view portions of hidden internal layers, which is suitable for geometric volume visualization. In this paper, algorithms, data structures, and the prototypal implementa- tion that allows interactive construction of virtual holes on 3D layered objects are presented.
