Make faces of cube transparent

Hello,

I have made a 3D cube but would like to have the faces appear transparent. How do I go about doing that? Thanks.

Here is my code:

vert = [0 0 0;1 0 0;1 1 0;0 1 0;0 0 1;1 0 1;1 1 1;0 1 1];
fac = [1 2 6 5;2 3 7 6;3 4 8 7;4 1 5 8;1 2 3 4;5 6 7 8];
patch('Vertices',vert,'Faces',fac,...
      'FaceVertexCData',hsv(6),'FaceColor','flat')

view(3)
axis vis3d
rotate3d
xlabel('x')
ylabel('y')
zlabel('z')

patch('Vertices',vert,'Faces',fac,...
      'FaceVertexCData',hsv(6),'FaceColor','flat', ...
      'FaceAlpha', 0.5);   % <== Add this

how we should opt the points for faces?

fac = [1 2 6 5;2 3 7 6;3 4 8 7;4 1 5 8;1 2 3 4;5 6 7 8];

this line is from above code....how these points are opted ?

Draw a cube.

Go around one of the square faces and label the corners 1, 2, 6, and 5 in that order.

Find the other square face that has the line between 2 and 6 as one of its edges.

Label the corner of that square next to 2 with a 3 and the one next to the 6 with a 7.

This gives you the [2 3 7 6] face.

Find the square face that has points labeled 1, 2, and 3. Label the remaining corner 4.

This gives you the [1 2 3 4] face.

Continue until all the points have been labeled. For this simple shape there's only one point left, the 8.

Each face will consist of the points representing one of the rows in the fac variable and the edges between those points.

Thanks I got it.

I have one more question.

[x y] = meshgrid(-6:1:6); % Generate x and y data

z = zeros(size(x,2)); % Generate z data

surf(x, y,z) % Plot the surface

view(2)

axis padded

hold on

vert = [0 0 0;3 0 0;3 3 0;0 3 0;0 0 3;3 0 3;3 3 3;0 3 3];

fac = [1 2 6 5;2 3 7 6;3 4 8 7;4 1 5 8;1 2 3 4;5 6 7 8];

patch('Vertices',vert,'Faces',fac,...

'FaceVertexCData',hsv(6),'FaceColor','flat', ...

'FaceAlpha', 0);

view(3)

axis vis3d

rotate3d

xlabel('x')

ylabel('y')

zlabel('z')

%theta in radian

In the above code, I have put the cube on image plane but how to centred the cube on the plane. Is it due to the lower face of cube of else?

could you modify it or give me some insight?
