matlab在三维坐标系中画二维动画曲线怎么做？

Question

在二维坐标中画二维动画曲线是用comet是吧？那在三维坐标系中怎么画二维动画呢？

Answer 1

有点像是这个样子【我改了一下朝向】

omega = 2*pi;
t = linspace(0,4,1001);
x = 2 + cos(omega*t);
y = 2 + sin(omega*t);
dt = min(diff(t));
t0 = -t;
z = -t;
figure(1)
for i = 1:1:10000
    t0 = t0 + dt;
    x = 2 + cos(omega*t0);
    y = 2 + sin(omega*t0);
    p = [y(1),z(1),x(1)];
    p1 = [y(1),z(1),0];
    p2 = [0,z(1),x(1)];
    plot3(y, z, x,  'g-');
    hold on
    plot3(y, z, zeros(size(x)),  'b-');
    plot3(zeros(size(x)),z, x,  'r-');
    plot3([p1(1),p(1)],[p1(2),p(2)],[p1(3),p(3)],'bo--','markersize',5,'markerfacecolor','b')
    plot3([p2(1),p(1)],[p2(2),p(2)],[p2(3),p(3)], 'ro--','markersize',5,'markerfacecolor','r')
    axis([min(x) max(x) min(y) max(y) -max(abs(z)) max(abs(z))])
    view([50.4,20.4])
    grid on
    axis equal
    pause(0.0001)
    hold off
end
