一、静态心形图绘制

（1）效果展示

（2）静态心形原始代码

 1 clc;
 2 clear all;
 3 const=0;
 4 % 均布三位坐标
 5 x=-5:0.05:5;
 6 y=-5:0.05:5;
 7 z=-5:0.05:5;
 8 [x,y,z]=meshgrid(x,y,z); % 绘制三位坐标点
 9 % 心形函数
10 f=(x.^2 + (9/4)*y.^2 + z.^2 - 1).^3 - x.^2.*z.^3 - (9/80)*y.^2.*z.^3-const;
11 p=patch(isosurface(x,y,z,f,0));  % 连接各点，组成封闭的图形
12 set(p, ‘FaceColor‘, ‘red‘, ‘EdgeColor‘, ‘none‘);
13 daspect([1 1 1])
14 view(3)
15 camlight; lighting phong

(2) 动态心形源代码

 1 clc;
 2 clear;
 3 filename=‘heart‘;
 4 % 三位坐标均布
 5 [x,y,z]=meshgrid(linspace(-3,3));
 6 % 心形函数
 7 p=(x.^2+(9/4)*y.^2+z.^2-1).^3-x.^2.*z.^3-(9/80)*y.^2.*z.^3;
 8 [faces,verts,colors] = isosurface(x,y,z,p,0,x);
 9 % 循环绘制心形形成的过程
10 for i=1:9
11 figure(i)
12 pp=patch(‘Faces‘,faces(1:284+i*1000,:),‘Vertices‘,verts);
13 set(pp,‘FaceColor‘,‘red‘,‘EdgeColor‘,‘none‘);
14 view(-30,24)
15 axis off
16 axis equal
17 axis tight
18 camlight
19 lighting gouraud
20 pause(0.5)
21 f(i) = getframe(i);
22 imind = frame2im(f(i));
23 [imind,cm] = rgb2ind(imind,256);
24 if i == 1
25
26         imwrite(imind,cm,filename,‘gif‘, ‘Loopcount‘,inf,‘DelayTime‘,0.5);
27 else
28         imwrite(imind,cm,filename,‘gif‘,‘WriteMode‘,‘append‘,‘DelayTime‘,0.5);
29 end
30 close(i)
