A method of generating and processing models of two-dimensional or three-dimensional objects in a computer and of reproducing said models on a display

摘要: A method of generating and processing models two-dimensional three-dimensional objects in a computer reproducing the on display is presented. The are created according to user's instruction by means geometric operations such as moving, rotating, enlarging, reducing and/or Boolean operations, connecting, forming points intersection, differentiation, from elements whose shapes already determined data stored or input into computer. It possible for these turn be constructed lower hierarchical level. menu commands pointer position controllable user through an inputting device shown outside image model so that can select specific parts marking associated place with pointer. Also, each element level, word also concerning relationship between hierarchically higher stored. structure diagram reproduced wherein indicated at corresponding which it belongs. mark when operation carried out lower-level elements.
