This is an example of how to produce an interpolated lighting across the surfaces in MATLAB®. This lighting is good for viewing curved surfaces.

Read about the `light` and `lighting` functions in MATLAB documentation.

% Create a grid of x and y points points = linspace(-2, 0, 20); [X, Y] = meshgrid(points, -points); % Define the function Z = f(X,Y) Z = 2./exp((X-.5).^2+Y.^2)-2./exp((X+.5).^2+Y.^2); % "phong" lighting is good for curved, interpolated surfaces. "gouraud" % is also good for curved surfaces surf(X, Y, Z) view(30, 30) shading interp light lighting phong title('Lighting phong')
