我正在尝试在 Matlab 中为旋转球体设置动画,但是球体上的照明会随之旋转。相反,我希望球体旋转,而照明在坐标系中保持固定。这是我的代码当前正在生成的 gif 图像:Animation。这是我的代码:
% Simulation Time
dt = 0.05;
time = 0:dt:5;
% Prep Figure
figure('Color',[1 1 1],'Renderer','zbuffer','ColorMap', [1,0,0; 0,0,1])
% Generate Sphere
[X,Y,Z] = sphere(20);
r = 0.75*25.4;
h = surf(r*X,r*Y,r*Z,Z,'FaceColor','interp');
hold on
% Adjust Axes, Lighting, and Shading
axis equal
view([40 25]);
light('Position',[1 1 1])
set(findobj(gca,'type','surface'),...
'FaceLighting','phong',...
'AmbientStrength',.3,'DiffuseStrength',.8,...
'SpecularStrength',.9,'SpecularExponent',25,...
'BackFaceLighting','unlit','EdgeColor','k')
filename = 'Rotation.gif';
for n = 1:36
rotate(h,[0 0 1],10,[0 0 0])
im = frame2im(getframe(1));
[imind,cm] = rgb2ind(im,256);
if n == 1;
imwrite(imind,cm,filename,'gif', 'Loopcount',inf,'DelayTime',dt);
else
imwrite(imind,cm,filename,'gif','WriteMode','append','DelayTime',dt);
end
end
