描述了三维自由曲面计算机辅助设计的实验系统。曲面在系统中表示为参数化基础样条线。该系统的主要特点是：(1) 表面在头戴式显示器上呈现为等参线图，它们是在三维“魔杖”的帮助下设计的，它允许控制表面形状的点进行 3D 运动，(2) 与表面的所有交互都是实时的，(3) 所使用的数学公式假设系统用户不了解它们。还检查了一些应该成为用于设计空间形式的实用 3D 系统的一部分的功能。
An experimental system for computer-aided design of free-form surfaces in three dimensions is described. The surfaces are represented in the system as parametric basis splines. The principal features of the system are: (1) the surfaces are rendered as isoparametric line drawings on a head-mounted display, and they are designed with the aid of a three-dimensional “wand,” which allows 3-D movements of the points controlling the shapes of the surfaces, (2) all of the interactions with the surfaces are in real-time, and (3) the mathematical formulations used assume no knowledge of them by the user of the system. Also examined are some of the features that should be part of a practical 3-D system for designing space-forms.
