详细说明：matlab编程，太阳地球月亮公转自转，球体贴图，基于matlab的仿真，实现了太阳的自转以及地球月球的自转公转。 k=6; n = 2^k-1; [x,y,z]=sphere(n ); A = imread('taiyang.png'); patches0=surf2patch(x,y,z,A); k=6; n = 2^k-1; [x,y,z]=sphere(n ); AA = imread('diqiu00.png'); patches1=surf2patch(x,y,z,AA); k=6; n = 2^k-1; [x,y,z]=sphere(n ); AAA = imread('yueqiu.png'); patches2=surf2patch(x,y,z,AAA); %set(patches,'edgecolor','none') % 设计太阳月亮地球的相对大小 Ssun=1; Searth=0.4; Smoon=0.2; % 设置太阳与地球间的距离 Res=4; % 设置地球与月亮之间的距离 Rme=1; alpha=0; beta=0; theta=0; % 设置旋转速度 step_a=0.1; %a的步长 step_b=0.2; %b的步长 step_t=0.05; %c的步长 % 设置太阳的位置 Csun=[0,0,0]; % 计时器 time=0; h=figure; % 取消坐标轴之类的属性 set(h,'toolbar','none','menubar','none','numbertitle','off') % 进入大循环 while 1==1 clf % 设置地球的位置 Cx=4*cos(alpha); Cy=4*sin(alpha); Cz=0; Cearth=[Cx,Cy,Cz]; Cmoon=[Cx+cos(2*alpha);Cy+sin(2*alpha);0;1]; patches_sun=patches0; % 绕z轴旋转坐标公式 Rz=[cos(5*theta) -sin(5*theta) 0;sin(5*theta) cos(5*theta) 0;0 0 1]; [len]=64*64; for i=1:len P=Rz*[patches0.vertices(i,1);patches0.vertices(i,2);patches0.vertices(i,3)]; patches_sun.vertices(i,1)=P(1); patches_sun.vertices(i,2)=P(2); patches_sun.vertices(i,3)=P(3); end patch(patches_sun),shading flat,hold on patches_moon=patches2; [len,t]=size(patches2.vertices); for i=1:len P=Rz*[patches2.vertices(i,1)*Smoon;patches2.vertices(i,2)*Smoon;patches2.vertices(i,3)*Smoon]+[Cmoon(1);Cmoon(2);Cmoon(3)]; patches_moon.vertices(i,1)=P(1); patches_moon.vertices(i,2)=P(2); patches_moon.vertices(i,3)=P(3); end patch(patches_moon),shading flat % 与改变太阳顶点值一致，改变地球的顶点值 patches_earth=patches1; [len,t]=size(patches1.vertices); for i=1:len P=Rz*[patches1.vertices(i,1)*Searth;patches1.vertices(i,2)*Searth;patches1.vertices(i,3)*Searth]+[Cx;Cy;Cz]; patches_earth.vertices(i,1)=P(1); patches_earth.vertices(i,2)=P(2); patches_earth.vertices(i,3)
