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

von Jan Möbius

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)

von David Lane

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

von Sebastian von Hippel

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

von xyliu80＠gmail.com

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?

How to add a new scene viewer?

von William Chu

Hello, One month ago I discovered OpenFlipper and I started working on a plugin. I am currently striving for adding a new scene viewer and I wish you could help me since I am having some difficulties. Here are the features I want to implement that give me troubles: My plugin can open a new popup window which shows a 2D-planar-view of the 3D-mesh currently loaded in the main OpenFlipper's viewport. In this popup, the user is provided with some features already available in the main Openflipper's viewport such as zoom/pan and pick. Actually, I digged into OpenMesh's Core and CoreWidget source code to check the main viewport's display and try to adapt it to my plugin. At this point, I am trying to copy the main scenegraph's structure and to create another scenegraph, handled by my plugin so that my plugin doesn't mess with OpenFlipper's own scenegraph. I am wondering if I am currently heading in the good direction or if it's possible to achieve my goals by the mean of adding nodes in Openflipper's main scenegraph, or any other way you could indicate me. Thanks for your help! William Chu
