Hi Syed,
As I understand, you would like to calculate the surface area and volume of a gyroid by adding to the code you have provided. Here is one possible way of obtaining it.
% Surface Area Calculation
SA = 0;
for i = 1:size(F3, 1)
v1 = V3(F3(i, 1), :);
v2 = V3(F3(i, 2), :);
v3 = V3(F3(i, 3), :);
edge1 = v2 - v1;
edge2 = v3 - v1;
area = 0.5 * norm(cross(edge1, edge2));
SA = SA + area;
end
% Volume Calculation
Volume = 0;
centroid = mean(V3, 1);
for i = 1:size(F3, 1)
v1 = V3(F3(i, 1), :);
v2 = V3(F3(i, 2), :);
v3 = V3(F3(i, 3), :);
Volume = Volume + abs(dot(v1 - centroid, cross(v2 - centroid, v3 - centroid))) / 6;
end
% Displaying the results
disp(['Surface Area: ', num2str(SA)]);
disp(['Volume: ', num2str(Volume)]);
This will output the required information.
Hope this helps!
