Openmesh, polygon triangulation

Does anyone know if the openmesh library can triangulate a simple closed polygon? I'm currently creating a PolyMesh, where the boundary is represented by a sequence of vertices defining a simple closed polygon. However whan I save this in .ply file…

Find neighbours / inside query in OpenMesh

I'm planning to use a mesh library, likely OpenMesh, to run simulations of surface mechanics for a convex topological surface. A crucial point is to have a good neighbour search, i.e. know which face/vertex is closest to a certain point in space.…

How to delete triangles from an openmesh without creating polygons?

When I call mesh.delete_face(face_handle) in an OpenMesh using OpenMesh::TriMesh_ArrayKernelT<> I get somehow faces with more than 3 vertices, possibly a polygon around the hole created by deleted faces. How can I avoid this to just get a boundary…

calculate the area of a triangle in openmesh

Here is a snippet from "Polygon mesh process" example: for (v_it=mesh_.vertices_begin(); v_it!=v_end; ++v_it) { area = 0.0; for (vf_it=mesh_.vf_iter(v_it); vf_it; ++vf_it) { fv_it = mesh_.fv_iter(vf_it); const Mesh::Point& P =…

Is there a way to reproject/interpolate vertex colors with OpenMesh?

I'm using OpenMesh to remesh/manage some mesh objects. With subdivide/decimate/smooth and other tools from OpenFlipper, I can change the mesh topology. This however results in vertex colors loosing their meaning, as new vertices will all have black…

OpenMesh Recursive Iteration

I recently started using OpenMesh, and I need to make a recursive iteration where I access one vertex, then its neighbouring vertexes and then the neighbours of those. I also need to keep a list of vertexes which I have used already. My main problem…

OpenMesh, decimation, Lindstrom-Turk

In my application I'm working with a lot of triangle meshes, and sometime I need to reduce number of triangles in them (colapse some edges). For mesh handling I use openmesh (openmesh.org) since it's modern (C++), but mainly because it does not drag…

Iterating over edges and getting their vertices with OpenMesh

I am starting to use OpenMesh to go through meshes which may have wholes and am wondering what is the good way to actually retrieve the vertices associated with each edge. For half-edges, there are the methods opposite_he_opposite_vh and opposite_vh…
