Hi, today we released OpenMesh 4.0 which is still fully backward compatible with the 2.x and 3.x branch. We marked some functions which should not be used anymore as deprecated and added hints which should be used instead. The version jump is mainly to indicate the changed license, which is now BSD-3. Although it's even more open we still encourage users of the library to submit bugfixes and improvements back to the project. The other changes incorporate mostly bugfixes. Next to these we added support for custom properties to the PLY reader and improved the documentation for the I/O section. This will be the last release supporting VS2008 and VS2010 and other compilers lacking C++11 support. As usual the full changelog is available on our website: http://www.openmesh.org/media/Documentations/OpenMesh-4.0-Documentation/a00… Best, Jan Möbius -- Dipl.Inform.

Save Boundary Edges

von yoshiyuki yamamoto

Hi OpenFlipper Users, Let me know how to save boundary edges as new file. Boundary edges were extracted as the attached file. However, I don't know how to save it.

Invalid face color

von MBRSL .

Hello, I'm using .obj for OpenFlipper. Is there any way to tell if a .obj contains face color or not from code? I found that if I checked "Load Face Colors" in the popup options, has_face_colors() will always return true no matter this .obj contains face color or not. The resulting color is invalid if this .obj does not contains face color. However, I can't tell this from my code. I would like to run a batch for several .objs that some of them contain face color and some others does not so I can't unchecked this option one by one manualy. Thanks, MBRSL

Showing both edges and faces colors at the same time

von MBRSL .

Hello, I'm trying to visualize data on mesh with color. However, I have trouble to show both edges and faces colors at the same time. Is there some tips or hacks to achieve it? If not, can I show edge colors in Hiddenline mode? EDGES_COLORED mode does not draw faces so it show the edges at rear that I do not need. Thanks, MBRSL

Re: [Openflipper] re-initialize plugin when user click on Clear all

von matthias.moeller＠rwth-aachen.de

Hi, I can just guess. Typicall errors: typo in function name? forgot to declare it as “slot”? private/public? forgot to inherited from the corresponding interface? The Move Plugin for example uses this Slot, maybe you can compare it with your plugin. Greets, Matthias Moeller Von: Juliette Pera Gesendet: ‎Donnerstag‎, ‎16‎. ‎April‎ ‎2015 ‎15‎:‎24 An: Matthias Möller Hi Matthias, Thank you for your answer! The thing is I already tried to use this slot and modify it in my code ( right now only display "cleared" ) but when I actually click on the "clear all" action, it doesn't seems to be executed. Do you know where it might comes from? Thanks again, Juliette 2015-04-16 15:10 GMT+02:00 Möller, Matthias <matthias.moeller(a)rwth-aachen.de>: Hi, you can use the slot from BaseInterface "slotAllCleared()"( http://openflipper.org/Daily-Builds/Doc/Free/Developer/a00314.html#aa00a311… ) for reciving the signal. The slot can be defined in your plugin and will be executed whenever a "clear all" action was performed via GUI or via script or in a plugin. Greets, Matthias M.

WG:Re: conversion from screen coordinates to mesh coordinates

von Möller, Matthias

forget CC ________________________________ Von: Möller, Matthias Gesendet: Donnerstag, 16. April 2015 15:16 An: Juliette Pera Betreff: AW: [Openflipper] conversion from screen coordinates to mesh coordinates Hi Juliette, if you just want the position on your mesh which is on the scenegraph, I would recommend to use the function "PluginFunctions::scenegraphPick(...)" (http://openflipper.org/Daily-Builds/Doc/Free/Developer/a03293.html#a0ae515c…) The last parameter "_hitPointPtr" gives you the hit point in world space. Hopefully I could help.

Fwd: QMouseEvent position

von Juliette Pera

Hi all, I am trying to drag a vertex of a mesh from its position to a new one using the two events: mouse button press and mouse button release. I can detect those two events and the positions of my mouse in the screen at both times. When I click the button close to a vertex, I use the following function in order to get the corresponding point in the coordinate system of my mesh: PluginFunctions::scenegraphPick(ACG::SceneGraph::PICK_ANYTHING,_event->pos (), node_idx, target_idx, &hitPoint); But once I move my mouse and release it, I can only get the position of my mouse in the screen. Do you know an easy way to convert the position of the mouse from the screen coordinate to my mesh coordinate? Thank you in advance, Juliette

Add an existing TriMesh into scene

von MBRSL .

Hello, I'm trying to add an existing TriMesh into scene but got some error. The TriMesh object is generated by myself (not by the core of OpenFlipper) to store the result of my algorithm. I would like to add it into scene but found no suitable functions. I tried to use LoadSaveInterface::addEmptyObject to create an empty TriMeshObject first and then change its underlying data using MeshObject<MeshT>::mesh(). This seems fine until I called OpenMesh::PolyMeshT<Kernel>::update_face_normals(). My debugger showed that the assertion in const PropertyT<T>& property(BasePropHandleT<T> _h) in PropertyContainer.hh failed when accessing point_ property. The point_ property is fine and I did call request_face_normals() before update_face_normals(). I also tested this mesh with TriMesh.point() and got no errors. Unlike previous case, it use static_cast so no assertion error occurs. For dependency reason, I need to separate algorithm from UI-related codes. So I would like to avoid using LoadSaveInterface::addEmptyObject in my algorithm class. And it's not possible for me to use LoadSaveInterface::addEmptyObject before my algorithm because I don't know how many meshes will be created. Any suggestion? Thank you. MBRSL
