[Gautam]

Hello Khadak,

To create a spherical indicatrix, you can follow the code below

t = linspace(0, 2*pi, 1000);  
a = 1;  
x = a * cos(t); 
y = a * sin(2*t) / 2; 

% Project onto a sphere 
z = sqrt(1 - x.^2 - y.^2); 

% Plot the sphere 
figure; 
[xs, ys, zs] = sphere(30); % Create a sphere 
mesh(xs, ys, zs, 'FaceAlpha', 1, 'EdgeColor', 'k'); % Plot the sphere 
hold on; 

% Plot the infinity symbol on the sphere 
plot3(x, y, z, 'r', 'LineWidth', 2); 

axis equal; 
xlabel('X'); 
ylabel('Y'); 
zlabel('Z'); 
grid on; 
hold off; 

This produces the following output
