How to add a new scene viewer?
by William Chu 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

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
