THE ENVELOPING OF A FAMILY OF Bl-PARAMETRIC SURFACES AND ITS APPLICATION

  • In this paper we derive the formula for computing the envelope of a bi-parametric family of surfaces, when they are expressed in parameters. We also develop a graph-analytic method for cacula ting cross roller shapes with revolving surfaces, when they are considered as envelopes of a bi-parametric family of spheres.
