[bug] UVs serialization broken (superfluous edges) when using .obj

Hi, As the title suggests. Tried with ready builds for 10.0 as well as compiled 11.0. I do not have access to GitLab, otherwise I would have posted there. The situation occurs both for quad (which are auto triangulated since I am using TriMesh) and tri meshes, for mesh of any kind of complexity, when using .obj as input (for instance monkey Suzanne from Blender), and when parametrized with OpenMesh::IO::Options::VertexTexCoord. Thank you in advance

Unable to set OpenMesh::Vec3f Color trait using OM 10.0
by mandasartur＠gmail.com 14 Dec '23

14 Dec '23

Hi, I want to parametrize my mesh with custom traits. I have added typedef OpenMesh::Vec4f Color trait and it works fine - I am able to set colors, read and write them, using .ply file format. The problem is my target is .obj which does not support alpha channel for vertex colors. When I try to add OpenMesh::Vec3f Color to my traits I get the following error during compilation: Severity Code Description Project File Line Suppression State Error C2027 use of undefined type 'OpenMesh::GenProg::AssertCompile<false>' nodeller I:\nodeller\Libraries\OpenMesh\include\OpenMesh\Core\Utils\vector_cast.hh 83 It seems to me I need to implement it myself, or is there a workaround? Thank you in advance

How use mesh.set_color with iterators and not smart handles?

Hi, Like in the subject of the thread. Also, how can I get a handle on the current vertex when using iterators, so that I can use set_color() with that? Thank you in advance

OpenMesh with OpenMP
by LuWang (Jack) 13 Dec '23

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

[OpenFlipper] Building only the backend part of OpenFlipper
by mandasartur＠gmail.com 11 Dec '23

Hi, First of all, thank you for making this great software (both OM and OF) free. My question is OF related, since I cannot joing OF mailing list. Can I build and use the backend only (math helpers + algorithms) or extract them to avoid including the Qt and ACG parts in my project? A more important question is: does the license allow that at all? Best regards
