Question

For generating Coons patch we require

(a) A set of grid points on surface

(b) A set of control points

(c) Four bounding curves defining surface

(d) Two bounding curves and a set of grid control points

I have been asked this question by my college director while I was bunking the class.

The question is from Computer Aided Analysis for Four Bar Mechanism topic in division Computer Aided Analysis and Synthesis of Mechanisms of Machine Dynamics

Answer 1

Correct choice is (c) Four bounding curves defining surface

For explanation I would say: Coons patch or surface is generated by the interpolation of 4 edge curves. A linear interpolation between four bounded curves is used to generate a Coons surface, also called as Coons patch. The method is credited to S. Coons who developed this concept for generating a surface.
