create a rotating cube in matlab

To create a rotating cube in Matlab using 3D graphics animation, you can follow the steps below:

main.m
% Define the coordinates of the cube vertices
v = [-1 -1 -1; -1 -1 1; -1 1 1; -1 1 -1; 1 -1 -1; 1 -1 1; 1 1 1; 1 1 -1];

% Define the faces of the cube using the vertex indices
f = [1 2 3 4; 2 6 7 3; 6 5 8 7; 5 1 4 8; 1 2 6 5; 4 3 7 8];

% Create a new figure
figure;

% Set the axis limits
axis([-2 2 -2 2 -2 2]);

% Set the view angle
view(45,30);

% Create a patch object for the cube
p = patch('Vertices', v, 'Faces', f, 'FaceColor', 'red', 'EdgeColor', 'black');

% Set the lighting properties
light('Position', [-1 -1 1], 'Style', 'infinite');
light('Position', [1 1 -1], 'Style', 'infinite');

% Set the rotation speed and angle increment
speed = 0.1; 
dtheta = pi/100;

% Start the animation loop
while true
    % Rotate the cube around the y-axis
    rotate(p, [0 1 0], dtheta);
    
    % Update the figure
    drawnow;
    
    % Pause for a short delay
    pause(speed);
end

In the code above, we first define the coordinates of the cube vertices and the faces of the cube using the vertex indices. We then create a new figure, set the axis limits and view angle, and create a patch object for the cube. We also set the lighting properties to make the cube appear more 3D.

Next, we define the rotation speed and angle increment, and start a while loop that continuously rotates the cube around the y-axis using the rotate function. We update the figure using drawnow and pause for a short delay using pause.

Once you run this code, you will get a rotating cube.
