function curve_struct(k, cpoint, t, hObject, handles)
% The function is used to create a new structure of a curve
% and save the new structure in the data handles
% The struct has the format:
%                           degree : k
%                           controlP: cpoint
%                           knotV: t
%                           curveP: C
%                           color: cc
%                           plotcurve: []
%                           plotcontrolP: []
%                           plotcpolygon: []

% the curve points
[C] = bspline_curve(k, t, cpoint);

% the color
cc = rand(3,1)';
