Couldn't compile the gigen.cpp

[ccCamila]

Thank you so much for your tutorial. I'm trying to use it but face the problems.

1. May I ask is this only used for windows system? I'm using it in Ubuntu.
2. Would you help me with the second part? Build cpp solution: this code is to generate geometry images. You can run this step in your local desktop.

I couldn't finish the compile part and face the problem. Here is the detail: The CMakLists.txt in local3Ddescriptorlearning-master/3dDescriptorLearning/cpp_geometry_images_generation include_directories( OpenMesh-6.3/src/OpenMesh ) # OpenMesh head files directory. I'm not sure is this the correct directories for OpenMesh head files in ubuntu. link_directories( OpenMesh-6.3/Release/Build/lib ) # OpenMesh lib files directory.

When I compile in 3dDescriptorLearning/cpp_geometry_images_generation/build I use i586-mingw32msvc-g++ -o gigen ../src/gigen.cpp -I ../include/ There are so many errors.

It should be wrong with my command. I want to compile cpp in ubuntu, so I use mingw32. But I could not compile it. There must be something wrong with this.

The config.ini in local3Ddescriptorlearning-master/3dDescriptorLearning/cpp_geometry_images_generationis this:

mesh_dir=local3Ddescriptorlearning-master/3dDescriptorLearning/dataset/MPI-FAUST/training
gi_dir=local3Ddescriptorlearning-master/3dDescriptorLearning/gi
kpi_dir=local3Ddescriptorlearning-master/3dDescriptorLearning/keypoints_faust256

Thank you so much for your help.

Hi, We only test the code of cpp solution in Windows. Maybe it is easier for you to generate geometry images in Windows. Then you copy the generated geometry images into ubuntu for training.

OK! Thank you so much! It's great.

May I ask which openmesh should I download? static or dll? Is 8.0 ok? Is there any special requirement?

Here is a tip when compiling it. generate config, the second one, you should choose x64 or win32 in cmake-gui. I choose x64 and then I can finally build it. It's quite confusing if you don't know it.

Here is the result:

Hi! Would you please give me some right screenshot because I couldn't use GIGen.exe and the error looks like this:

It seems the arrangement for the dataset is not right. How did you run this step in windows?

Here are my folders:

Here is the ini:

The folder "registritions" is downloaded from FAUST website:

gi/faust_256p and keypoints_faust256.kpi are two empty folders.

Thank you in advance!
