Hello Madam or Sir,
I am the user of OpenMesh, and I want ask some questions about the parallel code with OpenMesh, exactly, the parallel code is based on OpenMP on the VS2013.
The first question: When I use the OpenMP on the VS2013 to speed up the program which write with OpenMesh, for example, I add the code: #pragma omp parallel for num_threads(7) , just like the following:
and the errors follow, and I do not know why.
and the second question: Could the code with iterator of OpenMesh be paralleled by OpenMP just like " for (TriMesh::FaceIter f_it = mesh.faces_begin(); f_it != mesh.faces_end(); f_it++) " in the above picture? or How can I parallel the code with iterator of OpenMesh?
Thank you for your time! And I am looking forward to your reply.
Sincerely
LuWang
Hi,
i was wondering whether it's planned to support exporting meshes in glTF
format from openmesh?

Hello sir!
I am using OpenMesh for geometry processing but failed to compile. I looked up other people's error messages and how to deal with them, but I didn't see anything that worked for me. I don't know what went wrong with the error message.
My laptop is Apple M1, arm64. And my IDE is CLion.
The following sentences are the entire compilation error output:
