How to add a new scene viewer?
by William Chu 04 Jul '12

04 Jul '12

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

save/load properties with the OM format
by David Lane 25 Jun '12

25 Jun '12

Hi, I'm working with openFlipper and primarily using obj data files, but I was hoping to use the OpenMesh format to store a few simple vertex wise properties. I've found that OpenFlipper will successfully write an integer vertex property to a .OM file, but does not restore the properties on load. Does anyone have an idea where I might be going wrong, or if this might be a bug? Thanks, David Lane

Question about updateFromLocal & updateFromGlobal in Pose.hh
by Adam Hartshorne 25 Jun '12

25 Jun '12

The two methods, updateFromLocal & updateFromGlobal are stated to propagate the changes in coordinate system and also able to keep intact child nodes. They are both protected and as far as I am aware can't be directly called via something along these lines, Pose* pose...; int currentJointId.... ; pose->updateFromLocal(currentJointId) ; Searching through the openflipper project in visual studio, I can't see anywhere these methods are called. I presume when I make alternations to various poses I need to call some method, which will ultimately call these methods in order to perform the update of the various joints in a skeleton. Any help much appreciated, Adam

It seems you are trying to pass an OpenMesh::ArrayItem::Face object as the second parameter to operator() where in fact you have to pass a OpenMesh::ArrayKernel::FaceHandle object. > Send Openflipper mailing list submissions to > openflipper(a)lists.rwth-aachen.de > > To subscribe or unsubscribe via the World Wide Web, visit > http://mailman.rwth-aachen.de/mailman/listinfo/openflipper > or, via email, send a message with subject or body 'help' to > openflipper-request(a)lists.rwth-aachen.de > > You can reach the person managing the list at > openflipper-owner(a)lists.rwth-aachen.de > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Openflipper digest..." > > > Today's Topics: > > 1. no matching functio error (Bo Wu) > 2.

I am sorry to interfere into a discussion of a specific matter with something different. I am a big fan of the OpenFlipper. It’s a great project, very useful (we use it a lot at my3dscanner.com) and I bet it has a bright future. I would personally advertise it as much as I can just because it is good! But what is the intention of making an open-source with so obsolete communication tools? No blog, comments, facebook, Google project/Code – you name it! There are just no tools for discussing and improving, no tools for collaboration. Just emails. Isn’t it awkward? Is it done on purpose?

PluginFunctions::isProjectionOrthographic bug?
by Bengt Rosenberger 14 May '12

14 May '12

Hi! It seems PluginFunctions::isProjectionOrthographic checks for the viewer id being >= 0. That obviously doesn't work when passing ACTIVE_VIEWER which is -1. Shouldn't the method check for ACTIVE_VIEWER and use activeExaminer_ as the id in that case? It works when I manually pass PluginFunctions::activeExaminer. Bye!

OpenFlipper under MacOS
by André Kempe 02 May '12

02 May '12

Hej folks, I try to get OpenFlipper running under MacOS with XCode. However compilation always fails. I try to compile scheme ALL_BUILD, and in *fixbundle* in get an error *"Fixup_bundle: not a valid bundle"*. However I doubt that for debugging it is necessary to create a bundle at all. Is there a way to supress bundle creation completely?? I use XCode 4.2, CMake 2.8.8 and the latest SVN version of OpenFlipper. Thanks in advance for your help, André

TypeInterface and multiple types
by Bengt Rosenberger 11 Apr '12

11 Apr '12

Hi! I'm using a custom object type in my OpenFlipper plugin and I wondered if there is a way to have a single type plugin handle multiple object types? If not it would be very helpful to add this, as it's a pain to write a small plugin for each new object type. Using something like this it should be possible to enhanche TypeInterface without breaking old code: virtual bool TypeInterface::supportsType(DataType type) { return this->supportedType() == type; } virtual int TypeInterface::addEmpty(DataType type) { return this->addEmpty(); } Thanks for OpenFlipper and OpenMesh! Regards, Bengt
