How can I plot a specific size 3D bounding box (cube) around a 3D point? For example, the coordinate of the point is (10,5,10) and I need to draw a 3D bounding box size 20 (20x20x20) around the point such that the point is in the center (inside) of the 3D box.

在 MATLAB Online 中打开

P = [10,5,10] ;   % you center point 
L = [20,20,20] ;  % your cube dimensions 
O = P-L/2 ;       % Get the origin of cube so that P is at center 
plotcube(L,O,.8,[1 0 0]);   % use function plotcube 
hold on
plot3(P(1),P(2),P(3),'*k')

After plotting the cube how to store the coordinates of the 8 vertices of the cube generated?

You can make use of the following function: http://in.mathworks.com/matlabcentral/fileexchange/15161-plotcube

the function plots cube but not around a center point. how should I plot a cube around a point of interest? In 2D, it's like a square areound a point which is the center of it.
