OpenMesh with OpenMP

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

Non-manifold meshes

Hi, I am developing a photorgrammetry library OpenMVS <https://github.com/cdcseacave/openMVS> and I am looking at your library to repair the generated meshes. OpenMesh seems to have support for mesh decimation, smoothing, hole filling, but I searched all documentation and code and I didn't find if it is able to repair non-manifold meshes. Is OpenMesh able to import a non-manifold mesh and convert it to manifold mesh with as little deformation as possible (for example not simply removing all faces to a non-manifold vertex, but try to repair the surface at that point)? Thank you, Dan

join/combine two meshes

Hi, I was browsing the mailing list archive for other questions like this, but I found no results with an answer. I am trying to write a program that adds together multiple OFF meshes into one, but there doesn’t seem to be a function or operation that does this. Is there a reliable way to combine two or more meshes into one using OpenMesh? -Matt
