To generate the 3D objects efficiently and precisely, it is useful to introduce optimal assisting methods by software instead of using the special equipment of force feedback displays. On the basis of this idea, we develop a 3D modeler VLEGO in a virtual environment. VLEGO simulates toy blocks, and introduces a number of manipulation assisting methods for virtual object manipulation. The methods have the following three features: (1) limiting the relative positions of primitives in discrete fashion, (2) detecting mutual interference among primitives, and adjusting the positions to avoid collision, and (3) making flexible two-handed manipulation possible by the use of two 3D cursors. Thus, VLEGO can provide a virtual environment in which the intuitive and precise generation of shapes is possible without training. In this paper, the design principle and basic functions of VLEGO are described, and the effects on the working efficiency of the virtual object manipulation assisting methods of VLEGO are evaluated by experiments. © 1998 Scripta Technica, Electron Comm Jpn Pt 3, 81(11): 18–28, 1998 References 1 J.
