Designing Surfaces in 3-D

  title={Designing Surfaces in 3-D},
  author={James H. Clark},
  journal={Commun. ACM},
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… CONTINUE READING
