程式碼如下
t = 0:pi/180:2*pi*30;
r = linspace(5,0,length(t));
x = t/(2*pi);
y = r.*cos(t);
z = r.*sin(t);
plot3(x,y,z);
hold on
t = 0:pi/180:2*pi*30;
r = linspace(5,0,length(t));
x = t/(2*pi);
y = 10+r.*cos(t);
z = 5+r.*sin(t);
plot3(x,y,z,'g');
t = 0:pi/180:2*pi*30;
r = linspace(3,0,length(t));
x = t/(2*pi);
y = r.*cos(t);
z = 15+r.*sin(t);
plot3(x,y,z,'r');
畫了三個螺旋紋
不知道有沒有辦法讓尾巴收在一起
變成像一束花那樣
謝謝
