Hello OSGers! The last days I am playing with osgAnimation in order to implement something. I managed to make something work like I want it to but I don't know if this is the right approach or not. I will describe my problem and then I will describe my solution. I would be more than grateful if you could give my suggestions,advices,tips etc.
Problem: I have a skinned (it has a skeleton, it is based on bones) hand model in a DAE file. The model does not contain any keyframes or animation. I want to import this hand into my OSG application and be able to move the fingers independently using the k/b. The movement of the fingers is simple: only rotation around an axis. (have your palm wide open and try to make a fist, each finger rotates around one axis that passes through the joint). Solution: * I load the model normally. * I get a pointer to a bone(using an osg::NodeVisitor). * I get osgAnimation::UpdateBone callback for that bone * I get get the osgAnimation::StackedTransform from that osgAnimation::UpdateBone * I push_back() a new osgAnimation::StackedRotateAxisElement (I also store the pointer somewhere else) to the osgAnimation::StackedTransform * Then I pass (using the constructor) the previous stored osgAnimation::StackedRotateAxisTransform pointer to a custom EventHandler that inherits from osgGA::GUIEventHandler and I add it (the handler) to the osgViewer (using addEventhandler()). * Then inside the handler() function of my custom even handler I check for key presses and then I modify the angle of the osgAnimation::StackedRotateAxisTransform. All the above seem to work fine, but I don't know if this is the right way to solve this kind of problem. I would appreciate any comments/suggestions/ideas/tips. Thank you very much for your time!
