情節立方體在MATLAB

Question

我想繪製邊長爲10的立方體，這將是對稱-5到5，而不是-6〜4

xc=1; yc=1; zc=1; % coordinated of the center 
L=10;     % cube size (length of an edge) 
alpha=0.8;   % transparency (max=1=opaque) 

X = [0 0 0 0 0 1; 1 0 1 1 1 1; 1 0 1 1 1 1; 0 0 0 0 0 1]; 
Y = [0 0 0 0 1 0; 0 1 0 0 1 1; 0 1 1 1 1 1; 0 0 1 1 1 0]; 
Z = [0 0 1 0 0 0; 0 0 1 0 0 0; 1 1 1 0 1 1; 1 1 1 0 1 1]; 

C='blue';     % unicolor 

X = L*(X-0.5) + xc; 
Y = L*(Y-0.5) + yc; 
Z = L*(Z-0.5) + zc; 

fill3(X,Y,Z,C,'FaceAlpha',alpha); % draw cube 
axis equal 

Answer 1

我剛纔設置的中心(0,0,0)得到期望的結果：

xc=0; yc=0; zc=0; % coordinates of the center
