I have a 100*100*100 mat file with only 0 and 1 in it. Display three-dimensional image, and display three-dimensional slices based on this

like this!

Code is required！！！！！！！！！！

thanks

Hi,

To visualize a 100x100x100 matrix containing random 0s and 1s in MATLAB as 3D image and slices, you can use combination of “isosurface”, “patch” and “slice” functions.

Kindly go through the following step-by-step explanation:

Use MATLAB's “isosurface” function to extract the 3D surface where the value changes from 0 to 1, creating a clear boundary representation. Render the extracted surface using “patch” function. This function creates a polygonal representation of the “isosurface”.

% Visualize the 3D matrix using isosurface
figure;
p = patch(isosurface(data, 0.5));
isonormals(data, p);

Transition to slice visualization by selecting slice indices at the midpoint of each dimension. This choice allows you to view cross-sections of the data. Use the “slice” function to display these cross-sections. This function cuts through the 3D matrix at the specified indices, showing the internal layers of the data.

% Visualize slices
figure;
sliceX = 50; % X slice index
sliceY = 50; % Y slice index
sliceZ = 50; % Z slice index

% Display slices
h = slice(data, sliceX, sliceY, sliceZ);
set(h, 'EdgeColor', 'none');

You may refer to the following MathWorks documentation to know more about the functions mentioned above:

• isosurface: https://www.mathworks.com/support/search.html
• patch: https://www.mathworks.com/help/matlab/ref/patch.html
• slice: https://www.mathworks.com/help/matlab/ref/slice.html

I hope the solution provided above is helpful.
