FaceFaceIter Problem
by Marcel Makowski 27 Jul '11

27 Jul '11

Hallo, ich habe ein Problem mit den FaceFaceIter-Zirkulatoren. Mein Netz besteht aus 4 Dreiecken, die ein Simplex bilden. Initialisiert habe ich den Zirkulator so: MyMesh::FaceFaceIter ff_iter=mesh->ff_begin(this->face_handle(face_idx)) Wenn ich allerdings ff_iter.handle().idx() ausgeben lasse, erhalte ich -1. Ist denn noch irgend etwas zu beachten, bevor man die FaceFaceIter-Zirkulatoren benutzen kann ? Hier noch die Definition von MyMesh: struct MyTraits : public OpenMesh::DefaultTraits { typedef OpenMesh::Vec3d Point; typedef OpenMesh::Vec3d Normal; VertexAttributes(OpenMesh::Attributes::Status); FaceAttributes(OpenMesh::Attributes::Status); EdgeAttributes(OpenMesh::Attributes::Status); }; typedef OpenMesh::PolyMesh_ArrayKernelT<MyTraits> MyMesh; Vielen Dank im Voraus!

Resolved: Re: error while loading shared libraries
by Marcel Makowski 16 Jun '11

16 Jun '11

Hi Jan, I solved it in the following way: To the file /etc/ld.so.conf I added the line /usr/local/lib/OpenMesh as root. Then I did ldconfig as root and then it works. The Problem is, that the libraries are in the folder /usr/local/lib/OpenMesh. best regards, Marcel 2011/6/16 Jan Möbius <moebius(a)cs.rwth-aachen.de>: > On 16.06.2011 15:30, Marcel Makowski wrote: >> >> Hi Jan, >> >> thanks for your quick response. >> >> Before I started , I did call >>> >>> make install >> >> And the libraries were installed: >> >> masel@masel-x200:/usr/local/lib/OpenMesh$ ls >> libOpenMeshCore.a libOpenMeshCore.so.2.0 libOpenMeshTools.so >> libOpenMeshCore.so libOpenMeshTools.a libOpenMeshTools.so.2.0 >> >> I tried ldd cube, this is the output: >> >> >> masel@masel-x200:~/workspace/OpenMesh-2.0.1/src/OpenMesh/Examples/Tutorial01$ >> ldd cube >> linux-vdso.so.1 => (0x00007fff0ffd5000) >> libOpenMeshCore.so.2.0 => not found >> libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007f7bbda63000) >> libm.so.6 => /lib/libm.so.6 (0x00007f7bbd7df000) >> libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007f7bbd5c8000) >> libc.so.6 => /lib/libc.so.6 (0x00007f7bbd245000) >> /lib64/ld-linux-x86-64.so.2 (0x00007f7bbdd9a000) >> >> I tried copying libOpenMeshCore.so.2.0 into the Tutorial01 folder, >> but this doesn't help. > > Did you copy the lib libOpenMeshCore.so as well as the symlink?

On Mac: OpenGL Version
by Philip J. Schneider 05 May '11

05 May '11

Greetings - I have compiled OpenFlipper on my Mac Mini and upon starting up, I am greeted by a message that my driver/hardware does not support OpenGL 2.0. My Mini is rather old - it's an Intel Core Duo that is at least 5 years old, and so I am not surprised by this. Of course I had to build my own OpenFlipper because the compiled version that's available is 64-bit only, and my Mini is 32-bit. Perhaps I hoped I would get lucky :-) So my question is this: can I assume that a current iMac will have sufficient OpenGL support? The latest machine I will be getting has an AMD (ATI) Radeon HD 6970M card, which I think should be supporting OpenGL 2.1 at least... Thanks!

Faces einfärben
by Marcel Makowski 10 Feb '11

10 Feb '11

Hallo, ich würde gern wissen, ob und wie man Faces einfärben kann? Ein bestehendes Dreiecksnetz habe ich durch "Cluster" von gleichen Dreiecken angenähert und würde nun gern kongruente Dreiecke durch gleiche Farben markieren. Ich würde mich sehr über diesen Tip freuen. Vielen Dank im voraus. Gruß, Marcel Makowski (IGPM)
