    fileName = fullfile(toolboxdir("lidar"),"lidardata", ...
           "surfaceMesh","sphere.ply");
sphereMesh = readSurfaceMesh(fileName);

    Display the surface mesh.

    removeDefects(sphereMesh,"unreferenced-vertices")
surfaceMeshShow(sphereMesh,Title="Original Mesh")

    Define a bounding box to crop the sphere mesh to its lower half.

    bbox3d = [-1 1 -1 1 -1 0];
crop(sphereMesh,bbox3d)

    Display the cropped mesh.
