the equation below is the equation of a spherical gyroid.
sin x * cos y + sin y * cos z + sin z * cos x = 0
i want to write a code and save the file so i can export it and do a 3D printing.to obtain the different surface areas as shown below. i also want to model so i can obtain various specific surface areas as shown below

Use isosurface
clc,clear
cla
R = 10;
[x,y,z] = meshgrid(-R:0.3:R);
v = sin(x).*cos(y) + sin(y).*cos(z) + sin(z).*cos(x);
ix = x.^2+y.^2+z.^2 > R^2;
v(ix) = nan; % fill nan outside radius
p = isosurface(x,y,z,v,1); % change isovalue
patch(p,'facecolor','y','edgecolor','none')
camlight
material('metal')
axis vis3d
iso=-1 iso=0

Hello sir, how could I make the gyroid thick as it is on the pictures in the question?
Thanks for your help

What about simply use isosurface twice?
p = isosurface(x,y,z,v,1); % change isovalue
p = isosurface(x,y,z,v,0.98); % change isovalue
