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
Hello OpenMesh Team,
Thanks for developing OpenMesh and all of its features !
We got a problem when we try to switch to Eigen::vector3d as data type,
specifiing the mesh as desribed in
https://www.openmesh.org/media/Documentations/OpenMesh-Doc-Latest/a04077.ht…
always leads to an Error
C2440 '<function-style-cast>': cannot convert from 'const
Eigen::Matrix<double,3,1,0,3,1>' to 'OpenMesh::NormalConeT<double>'
(compiling source file
include\OpenMesh\Tools\Decimater\ModNormalDeviationT.hh 224
Line 224 of ModNormalDeviationT.hh
merge(NormalCone(mesh_.normal(*vf_it)));
there a Eigen::Vector3d can not be converted to a scalar. When i switch
back from Eigen representaion, everything works.
We are using Visual Studio 2017 an OpenMesh 8.0.
Thanks and best regards,
Matthias Hackel

Hi,
Thanks for the good work on the OpenMesh Decimation Framework. I have two questions to check:
1. Is it possible to add support for mesh with texture coordinates. It means that while decimation, the algorithm will also take the texture coordinates change(UV shell/island shape) into consideration. In short, it not only maintains the geometry, but also tries to preserve the seam line?
Something similar to Seam Aware Decimation: "https://cragl.cs.gmu.edu/seamless/", https://github.com/songrun/SeamAwareDecimater
2. If it is, how hard(how much effect) is it to add this kind of support, can you give a direction on it?
Thanks & Regards,
Spencer
Hello, I am a researcher for mesh processing, and I'm using your openmesh library. thanks for your development working, but I got a bug when I run you official code, "building a cube" [http://www.openmesh.org/media/Documentations/OpenMesh-Doc-Latest/a04088.html]. No matter whether I type codes by myself or copy your example code , there will always be a bug saying that there is a unexpectation occurring, that there is visiting conflict in posision 0x00000000000000.
