make 3d bridge in matlab

main.m
% Define bridge parameters
span = 100; % Span of the bridge in meters
width = 20; % Width of the bridge in meters
height = 10; % Height of the bridge in meters
num_cables = 6; % Number of support cables
cable_radius = 0.2; % Radius of support cables in meters

% Generate bridge mesh
[X,Y] = meshgrid(linspace(-width/2,width/2,10),linspace(0,span,100));
Z = -height/10*(cos(2*X/width*pi)+1).*X.^2/width^2+height;
surf(X,Y,Z,'FaceColor','white','EdgeColor','black');

hold on;

% Generate support cables
theta = linspace(0,2*pi,num_cables+1);
theta = theta(1:end-1);
x = cable_radius*cos(theta);
y = span/num_cables/2+linspace(-span/num_cables/2,span/num_cables/2,num_cables);
z = cable_radius*sin(theta);
for i = 1:num_cables
    plot3(x,y(i)*ones(size(x)),z,'-k','LineWidth',2);
end

% Set view and axis limits
view(-30,30);
axis equal;
xlim([-width/2,width/2]);
ylim([0,span]);
zlim([-height,2*height]);

% Set labels and title
xlabel('Width (m)');
ylabel('Span (m)');
zlabel('Height (m)');
title('3D Bridge');
