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
Wow, thank you! That worked great. Those methods have made it really easy
to move between OpenMesh and TriMesh (https://trimsh.org/) which provides
more import options and a scene graph. Combining these two libraries really
makes for a very powerful python API.
My goal is to use OpenMesh for decimation. The next thing I bumped into was
that the python API appears to have removed
<https://www.graphics.rwth-aachen.de:9000/OpenMesh/openmesh-python/commit/ec…>
the ability to "lock
<https://www.openmesh.org/media/Documentations/OpenMesh-6.1-Documentation/a0…>"
vertices. Do you know if there is a new way of doing so or why that
functionality was removed?

Best regards,
Jesse
