2. 在GUIDE中鼠标右键点击选择素材文件夹按键，选择查看回调＝＞callback编辑回调函数。

function pushbutton1_Callback(hObject, eventdata, handles)
binPath = uigetdir();
fileName = dir(fullfile(binPath,'*.ply'));
set(handles.edit1,'String',binPath);
[m,~] = size(fileName);
for i = 1:m
    listbox(i) = string(fileName(i).name);
end
set(handles.listbox1,'string',listbox);

3. 在GUIDE中鼠标右键点击绘制点云按键，选择查看回调->callback编辑回调函数。

function pushbutton2_Callback(hObject, eventdata, handles)
Path = get(handles.edit1,'string');
num = get(handles.listbox1,'value');
filename = get(handles.listbox1,'string');
f = fullfile(Path,filename(num));
fid = pcread(string(f));
axes(handles.axes);
cla reset;
pcshow(fid);
hold on;grid on;
pause(1);

4. 在GUIDE中鼠标右键点击绘制凸包，编辑回调函数

function pushbutton3_Callback(hObject, eventdata, handles)
Path = get(handles.edit1,'string');
num = get(handles.listbox1,'value');

filename = get(handles.listbox1,'string');
f = fullfile(Path,filename(num));
fid = pcread(string(f));
a = double(fid.Location);
k = convhull(a,'simplify', true);
axes(handles.axes);
trimesh(k,a(:,1),a(:,2),a(:,3),'FaceAlpha',0.5);
