combining 2 3D Plot

Dear, I have some 3D Data as zou can see in the photo bellow. (Bilder 1)

I need to create a cube, in a specific position and plot this cube in the sabe plot where my data is. and the data that are inside of the plot I will not be able to see (because the faces of the Cube will hide) However the points that are outside I will still be able to see them.

For example; Imagem that my cube has the folloing vertices: (-0.5 , 0.5 , 0.5), (0.5 , 0.5 , 0.5), (-0.5 ,-0.5 , 0.5) ,(0.5 ,-0.5 , 0.5), (-0.5 , 0.5 , -0.5), (0.5 , 0.5 , -0.5), (-0.5 ,-0.5 , -0.5), (0.5 ,-0.5 , -0.5).

How to add this cube in the 3D plot above.

Hi,

Please try the below code to achieve what you have asked for:

figure
[X,Y,Z] = sphere(16);
x = [0.5*X(:); 0.75*X(:); X(:)];
y = [0.5*Y(:); 0.75*Y(:); Y(:)];
z = [0.5*Z(:); 0.75*Z(:); Z(:)];
scatter3(x,y,z)

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

where the plotcube function is take from: https://www.mathworks.com/matlabcentral/fileexchange/15161-plotcube
