詳解

Defines Spoint seq of a space dimension and of a size.

MGSPointSeq is designed to represent a control polygon network of B-Spline surface. MGSPointSeq has its capacity and actual length used. The dimensioning is like MGSPointSeq spoint(i,j,k). i has u direction length nu, j has v direction length nv, and k has space dimension sd. Then minimum area size is nu*nv*sd, and 0<=i<nu, 0<=j<nv, 0<=k<sd.
