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

Store/Restore custom property of type 'vector<T>' with dynamic size?

von 王少东

Hi, OpenMesh has implemented the functionalities to s/r custom property of vector<T> in OpenMesh/Core/IO/SR_binary_vector_of_fundamentals.inl. However it seems to expect the size to be known in advance when restoring. Is there a way to restore the size dynamically? I think maybe it's better to store the size as well? Kind regards

Setting the points from stl vector

von sinan mutlu

Hi, Is it possible in OpenMesh C++ to set the vertex positions from an stl container or from another object directly instead of looping on the mesh using the vertex iterators. Thanks, Best Regards, Sinan

Lumberyard White Box Tool

von hultonha＠amazon.co.uk

Hello there! I wanted to let people know that a new tool released as part of the Lumberyard Editor called the White Box Tool is built using the Open Mesh library. We have an announcement video showing off the MVP - https://youtu.be/nV2tm19FmYI?t=130 For more information please find the documentation here - https://docs.aws.amazon.com/lumberyard/latest/userguide/gem-white-box.html The Release Notes for the latest release can be found here - https://aws.amazon.com/about-aws/whats-new/2020/07/lumberyard-beta-1-25-ava… And finally if you want to have a look at the code it’s available on GitHub - https://github.com/aws/lumberyard/tree/master/dev/Gems/WhiteBox (a gotcha is looking on GitHub it might seem that some of the OpenMesh files are missing but that’s because Lumberyard is so large we can’t keep all the files on GitHub – if you sync the repo and then run git_bootstrap.exe it’ll download the remaining files). Thanks again for an excellent library, the docs were fantastic and we're hoping to be able to merge our minimal updates back soon if you're interested! Kind regards, Tom

Interoperate OpenMesh with Open3D

von Fulin Xiang

Hello, I want to use OpenMesh together with Open3D to process point cloud. Just wonder • If OpenMesh can create mesh from 3D points? • If OpenMesh can extract points from mesh? • If OpenMesh can import Open3D mesh and vice versa via eigen matrix? Thank you in advance for your help! --Fulin Xiang https://github.com/intel-isl/Open3D/blob/master/examples/cpp/TriangleMesh.c… http://www.open3d.org/docs/release/tutorial/Basic/mesh.html

Feature Request: Use type traits for the floating point types for mesh import and export

von Alexander Schier

Hello everyone. I noticed that the OBJWriter and PLYWriter use hardcoded "float" and "Vec3f" variables instead of the type traits of the mesh. It would be nice when these routines would follow the type traits. I explicitely use double in my type traits, as some of my algorithms do not converge with single precision. with kind regards, Alexander Schier
