Here's an example code to create a simple airplane model using Matlab's built-in 3D plotting functions:
% Create a figure window
figure('Color',[0.8 0.8 1], 'Name','Airplane')
hold on
axis equal; grid on; view(3); xlabel('x'); ylabel('y'); zlabel('z')
% Define the airplane geometry using simple 3D lines
BS = [0 0 0; 5 0 0; 5 0 -1; 4 0 -1; 4 1 -1; 5 1 -1; 5 1 0; 0 1 0; 0 1 -1; 0 0 -1; 0 0 0];
HS = [-1 0 -1; -1 0 -2; -2 0 -2; -2 0 -3; -3 0 -3; -3 0 -2; -4 0 -2; -4 0 -1; -3 0 -1; -3 0 0; -2 0 0; -2 0 -1; -1 0 -1];
FS = [-0.5 0 -0.5; -0.5 0 -1.5; -0.5 -1.5 -1.5; -0.5 -1.5 -0.5; -0.5 0 -0.5];
RS = [0.5 0 -0.5; 0.5 0 -1.5; 0.5 -1.5 -1.5; 0.5 -1.5 -0.5; 0.5 0 -0.5];
LW = [0 0.1 0; -0.2 0.2 0; 0 0.2 0; 0.2 0.2 0; 0 0.1 0];
RW = [0 -0.1 0; -0.2 -0.2 0; 0 -0.2 0; 0.2 -0.2 0; 0 -0.1 0];
% Plot the airplane using different line styles and colors for each part
plot3(BS(:,1),BS(:,2),BS(:,3),'b','LineWidth',2)
plot3(HS(:,1),HS(:,2),HS(:,3),'b','LineWidth',2)
plot3(FS(:,1),FS(:,2),FS(:,3),'b:','LineWidth',2)
plot3(RS(:,1),RS(:,2),RS(:,3),'b:','LineWidth',2)
plot3(LW(:,1),LW(:,2),LW(:,3),'k','LineWidth',1.5)
plot3(RW(:,1),RW(:,2),RW(:,3),'k','LineWidth',1.5)
% Adjust the plot limits and camera position
xlim([-5 5]); ylim([-2 2]); zlim([-3 1]);
campos([-15 -15 -15]); camzoom(1.5)
This code creates a 3D plot of different parts of the airplane, including the body, horizontal and vertical stabilizers, front and rear spoilers, and landing wheels. You can modify the coordinates and line styles to create your own custom airplane design. Note that this is just a simple visual representation and does not include any physics-based simulations or computational fluid dynamics.
