plot a lightbulb in matlab

To plot a lightbulb in matlab, you can use the "sphere" function to create a sphere and then add a texture map to it. Here is some example code to get started:

main.m
% Define the lightbulb shape
[x,y,z] = sphere;
r = 2; % Set the radius of the bulb
x = x*r;
y = y*r;
z = z*r;

% Load the lightbulb texture map
img = imread('lightbulb_texture.png');

% Plot the lightbulb
figure
surf(x,y,z,'FaceColor','texturemap','CData',img,'EdgeColor','none')
axis equal

In this example, we create a sphere with radius r by scaling the built-in sphere function. Then, we load a texture map of a lightbulb using the imread function, which reads image files into matlab. Finally, we plot the sphere using surf, setting the color of each face to the corresponding pixel of the texture map. The axis equal command ensures that the x, y, and z axes are scaled uniformly so the sphere looks like a sphere, not an ellipsoid.

You will need to save a lightbulb texture map as a .png file in your working directory or specify the file path to the texture map file.
