Question about UpdateTypes
by Vladimir, Chalupecky 05 Sep '12

05 Sep '12

Hi again, I have a question about UpdateTypes and a proper way to respond to updatedObject in slotObjectUpdated. In my plugin I would like to respond to changes in an object coming from the Move plugin, from the MoveSelection in particular. The user selects vertices, transforms them using a manipulator and the plugin recomputes the position of the remaining vertices. At present I have in slotObjectUpdated something like this: if (!type.contains(UPDATE_GEOMETRY) || PluginFunctions::pickMode() != "MoveSelection") { return; // we are not interested and don't want to respond } However, any update to my object from another plugin while I am in the MoveSelection pick mode will go through. What would be the right way to go about this? A related question: why for example clearModelingArea from Plugin-SelectionMeshObject emits UPDATE_ALL if it does not modify geometry or topology of the object? Another related question: if I add a property to an object, I would like to notify other plugins about it (e.g., PropertyVis). How would I do it? Thanks a lot for your help, Vladimir

Edge coloring
by Erkan Gunpinar 05 Sep '12

05 Sep '12

Dear Möbius, I would like to ask about giving colors to the edges and visualizing them on the Openflipper visualization framework. Here is my code, but I cannot see the colored edges; m_mesh->request_edge_colors(); m_mesh->set_color(m_mesh->edge_handle(0), PolyMesh::Color(0, 255, 0)); PluginFunctions::setDrawMode(ACG::SceneGraph::DrawModes::EDGES_COLORED); emit updatedObject(m_targetObject->id(), UPDATE_COLOR); Thank you.

Bug in PLY exporter with vertex colors?
by Bengt Rosenberger 04 Sep '12

04 Sep '12

Hi! I was trying to export a TriMesh to the PLY file format with vertex colors. The mesh looks as expected in OpenFlipper. But the exported mesh was all black in MeshLab. When looking at the PLY file, the components of the colors were all either 0 or 1. I believe there is a bug in the PLY exporter. TriTraits::Color is defined as Vec4f. FilePLYT.cc exports this as ofs << " " << OpenMesh::color_cast<OpenMesh::Vec3i>(c); That means, that in fact OpenMesh::color_coder<Vec3i, Vec4f> is used for the conversion. Since there is no such specialization of color_coder, the default template will be used, which just converts to int. Thus, the resulting colors will all be not correct. Shouldn't it be this? ofs << " " << OpenMesh::color_cast<OpenMesh::Vec3uc>(c); Bye, Bengt

The problem with showStatusMessage
by 刘先勇 27 Jul '12

27 Jul '12

Dear openflipper, Last time, we raised Vol 29, Issue 5. According to your suggestion, we chagned code to : *int intObjectID = PluginFunctions::getObjectId(strPrameterizationObjectName); PluginFunctions::setDrawMode(ACG::SceneGraph::DrawModes::POINTS_SHADED, 1); emit updatedObject(intObjectID, UPDATE_COLOR );*/ Unfortunately, I found that it did not work. The color did not show up. Besides, we have a new problem with the code below. Compiling and running the following are fine. The problem is line 1 works fine, but line 2 give no message in the status bar. Line1: QMessageBox::information(NULL, "Scene Position", string, QMessageBox::Yes, QMessageBox::Yes); Line2: emit showStatusMessage(string, 100); Thank for your help! THANKS VERY MUCH FOR YOUR GREAT WORK!!

OpenFlipper 1.3 released
by Jan Möbius 25 Jul '12

25 Jul '12

Hi, OpenFlipper 1.3 has been released. This release adds some new functionality. The poly line has been added as a new data type. It can be moved across a surface, and has build in algorithms for smoothing, decimation and subdivision. The ruler plugin is now available and can be used to measure the euclidean distance between objects in the 3D scene. The subdivider has been extended by a Catmull-Clark algorithm for QuadMeshes and various other plugins got improvements or bugfixes. Furthermore there were various updates for gcc-4.7 compatibility and documentation improvements. For a full list of changes please look into the changelog. http://openflipper.org/Documentation/OpenFlipper-1.3/changelog.html Best, Jan Möbius -- Dipl.Inform.

problem with signal updatedObject(int, UpdateType)
by David Lane 24 Jul '12

24 Jul '12

Hi, I've tried using: emit updatedObject(-1, UPDATE_ALL) after performing an operation that updates a number of objects within in the scene. The documentation implies that this should call updatedObject for all objects, it doesn't seem to work. I'm currently using OpenFlipper 1.2, but I don't see a mention of this in the changelog for 1.3. Regards, David Lane

How can i access a Vertex Property in a Shader
by Sebastian von Hippel 24 Jul '12

24 Jul '12

Hi, i want to write a shader, that sums up all values of a vertexproperty for all visible vertices and one with which i compute the color for each vertex using a vertexproperty. Are vertexproperties being pushed automatically into the pipeline or do i have to assign them manually? If necessary what needs to be done so that a shader can use a property and how can i access that property in my vertex shader. I already thought about a workaround, storing the property value for a vertex in a texture but is there a better way? Best Regards Sebastian von Hippel

Re: [Openflipper] How can we set a color for a vertex in code
by xyliu80＠gmail.com 22 Jul '12

22 Jul '12

Dear OpenFlipper, We really appreciate your feedback in such a quick time!! Now, by following your instruction, both the compiling and running are fine without error pop-up. Here is our code: _mesh->set_color(_mesh->vertex_handle(intLoopBeginningVertexHandle), TriMesh::Color(0.7,0.286,0.5568,1.0)); HOWEVER, we found that the vertex color of mesh in viewport did not change at all. It was still in red(selection status). In code, we would like to change the color of those vertices which formed a boundary of a region. Could you please share us with your idea?
