詳解

Defines BPoint seq of a space dimension and of a capacity.

MGBPointSeq is an array of world coordinates of a space dimension(any number), desined especially for MGLBRep class's control polygon handling. Let n be a B-rep dimension(i.e., number of points of the control polygon), and sd be a space dimension, then MGBPointSeq bp has the minimum area of n*sd. The subscription of MGBPointSeq bp is 2 dimension as bp(i,j), 0<=i<n, and 0<=j<sd. If MGBPointSeq can be considered as a Matrix of n by sd.
