Which operating system and compiler are you using?
You need a compiler that supports C++11.

MavAlex · Answer 2 · Mon Jan 06 2020 18:47:14 GMT+0800 (China Standard Time)

thanks for your reply!
My operating system is ubuntu16
And here is my compiler information:
-- The C compiler identification is GNU 4.8.5
-- The CXX compiler identification is GNU 4.8.5
And when i make this project,the error occured:

Liangliang Nan · Answer 3 · Mon Jan 06 2020 19:21:20 GMT+0800 (China Standard Time)

Some features of the Timer require C++14, and it seems your compiler doesn't support that. You can try to replace
set (CMAKE_CXX_STANDARD 11) # in file CMakeLists.txt in the root directory of adtree.
by
set (CMAKE_CXX_STANDARD 14)
If it still doesn't work, we can confirm that your compiler doesn't support C++14.

Then a simple workaround is to just comment out the following lines and let me know how it works:
#include <easy3d/util/timer.h> // line 62
and

    const int delay = 2000;               //  line 510
    Timer::single_shot(delay, [&]() {
        show_pivot_point_ = false;
        pivot_point_ = vec2(0, 0);
        update();
    });

Hello liangliang,after i changed the file CMakeLists.txt as you said, it didn't work still,
by the way,where is the file that i should comment out:)

Liangliang Nan · Answer 5 · Mon Jan 06 2020 20:28:33 GMT+0800 (China Standard Time)

(As the errors pointed out) It is in /3rd_party/easy3d/viewer/viewer.cpp .

MavAlex · Answer 6 · Mon Jan 06 2020 20:41:14 GMT+0800 (China Standard Time)

after i comment out these line i get this exciting result:
[100%] Built target AdTree
thanks for your patience and your work is very enlightening to me:)

Liangliang Nan · Answer 7 · Mon Jan 06 2020 20:45:56 GMT+0800 (China Standard Time)

Great to hear that. Good luck with your work/research!

When you run the program, you should have seen the menus.
Open a point cloud file, and click on one of the menus under "Reconstruction". This demo version has very few menus.

You should have tried a bit before you ask a question :-)

Were you able to generate results from some point clouds (e.g., the examples in the 'data' folder)?

liangliang,so sorry unable to reply for the past few days
when i run this excutable file: build/bin/AdTree,this is the result:
(base) rthpc@Rt:~/anaconda3/envs/code/ADTree/build/bin$ ./AdTree
GLFW error 65542: GLX: GLX version 1.3 is required
terminate called after throwing an instance of 'std::runtime_error'
what(): Could not create an OpenGL 3.2 context!
已放弃 (核心已转储)
i heard ubuntu 16.04 does not support GLX1.3, so i need to upgrade the operating system?

Hi, I don't think it was the problem of the OS. The only thing that matters is the graphics driver. AdTree runs on my old computer from 2009. So I am pretty sure it should run on ubuntu 16.04 (which was released in 2016). I notice you ran AdTree from ~/anaconda3/envs/code/ADTree/build/bin$ I don't know if anaconda3 is your user name. If it is something related to Anaconda, then Anaconda may override some environment variables, e.g., blocking applications from using their default settings. So please first get out of the Anaconda (do this only if anaconda3 is Anaconda related), and use the normal terminal. Then run AdTree. If it still doesn't work, install OpenGL/X11/GLX development environment on Ubuntu using sudo apt-get install mesa-common-dev libgl1-mesa-dev libglu1-mesa-dev Then compile and run. If still errors, please run sudo apt-get update sudo apt-get upgrade Then compile and run. If you reach here, please check the OpenGL version using glxinfo (this will report some infomation about your graphics driver), and I'd love to see the output of glxinfoto help you further.

hello liangliang,after i changed an computer which runs ubuntu18 to run this program the problem was solved! i can get the reconstruction result on your pointcloud now!
But how can i change the code if i want to get the skeleton before cylinder fitting since the GUI doesnt gives an option?And if possible i want to get the result after every single step(like skeleton extract,simplifying..) what should i do?can i change the radius of the tree branch which is related to its weight in your paper? you know for a tree or plant is too small the radius you set in your paper might not be suitable since the radius of branch are almost the same with main trunk

Good to know. But still, did you try the proposed solution on your "old" Linux? I guess that should also work.
I just added the support to export skeletons, i.e., save the skeleton into a file (in PLY format). After you load it into the easy3d viewer, you can press v to hide/show the vertices.

well just now i tried to export the skeleton after "reconstruction skeleton" but failed,the information on terminal is"not implemented yet"

You forget to update the code. -- Liangliang
