Dear all,
I need to move an object along a line with the speed of 1m/s. The

Dear all,
I'm using OpenSceneGraph 2.8.2 with C++, and notice that when I move

objects are blur. I don't like that effect and would like to disable
it. Could anybody tell me how?
Thanks,

Dear all,
I have a very basic question of how to capture key pressed event in
OpenSceneGraph.
My program is set up like this:
osgProducer::Viewer *viewer = new osgProducer::Viewer();
//some more initialization here
Producer::KeyboardMouse* km = viewer-getKeyboardMouse();
, but this is my plan - to migrate all
stereo support into the high level class, and then provide
configuration file support for it. This will be done well after 2.8.
