How to create 3D shape of square or triangle by using matlab

Hi,
Creating 3D shapes in MATLAB can be done using various functions depending on the type of 3D visualization you want. For a 3D square (which is actually a cube) or a 3D triangle (which could be interpreted as a tetrahedron or a triangular prism), you can use the patch’or ‘surf’ functions to draw the faces of these shapes.
For more information on functions mentioned above, kindly refer to the following MathWorks documentations:
Additionally, following example code to create Tetrahedron (3D Triangle) could be helpful.
% Define the vertices of the tetrahedron
vertices = [0 0 0; 1 0 0; 0.5 sqrt(3)/2 0; 0.5 sqrt(3)/6 sqrt(6)/3];
% Define the faces of the tetrahedron
faces = [1 2 3; % Base
1 2 4; % Side
2 3 4; % Side
3 1 4]; % Side
% Create the 3D patch
patch('Vertices', vertices, 'Faces', faces, ...
'FaceColor', 'r'); % You can specify different colors
% Set the aspect ratio and the viewing angle
axis equal;
view(3);
grid on;
xlabel('X-axis');
ylabel('Y-axis');
zlabel('Z-axis');
title('3D Tetrahedron');
I hope information provided above is helpful.
