    Define mesh vertices for a surface mesh.

    vertices = [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 mesh faces using the vertices.

    faces = [6 2 1; 1 5 6; 8 4 3; 3 7 8; 6 7 3; 3 2 6; ...
         5 1 4; 4 8 5; 4 1 2; 2 3 4; 7 6 5; 5 8 7];

    Create and display the surface mesh.

    mesh = surfaceMesh(vertices,faces);
surfaceMeshShow(mesh)

    Define rotation and translation values, then use them to generate a transformation matrix.

    theta = 30; 
rotationMat = [cosd(theta)  sind(theta) 0;
              -sind(theta) cosd(theta) 0;
                  0            0       1];
translationVector = [2 0 0]; 
tform = rigidtform3d(rotationMat,translationVector);

    Apply the rigid transformation and visualize the output.

    transform(mesh,tform);
surfaceMeshShow(mesh)
