How to extend this code to 3 dimension to get a sphere and how to visualize it?

I have a code with 2 dimension: Nx and Ny. With the following condition i can get the circle of radius 5. Now i want to extend it into 3 dimension Nx, Ny and Nz. The purpose is to get the sphere. How to extend it and which commands should i used to see the output?
Note: I am not looking into any inbuilt function to generate the sphere. Just looking for the extension of this code segment
The code is:
Nx = 64;
Ny = 64;
p = zeros(Nx,Ny);
for i=1:Nx
for j=1:Ny
if ((i-Nx/2)*(i-Nx/2)+(j-Ny/2)*(j-Ny/2) < 10)
p(i,j) = 1.0;
end
end
end

To extend the code to generate a sphere in 3D, you can introduce an additional dimension Nz and modify the condition inside the nested loops. Here's an extended version of the code:
Nx = 64;
Ny = 64;
Nz = 64;
p = zeros(Nx, Ny, Nz);
for i = 1:Nx
for j = 1:Ny
for k = 1:Nz
if ((i-Nx/2)*(i-Nx/2) + (j-Ny/2)*(j-Ny/2) + (k-Nz/2)*(k-Nz/2) < 10^2)
p(i, j, k) = 1.0;
end
end
end
end
slice(p, [], [], 1:Nz);
axis equal;
