Hi,
I have used OpenSceneGraph 2.2.x for quite some time and have now
upgraded to 2.8.2.
I found that picking shape Drawables has become very very unprecise.
This can be reproduced with the osgpick-example. The drawable is still
picked even if the mouse is miles away. This error did not occur with
the 2.2.x series, if that helps to find out where this behaviour might
come from.
I attach a sample osg-file that can be used with the 2.8.2. osgpick
example to reproduce the bug. It is a very long and thin cylinder, maybe
this strange shape makes the bug appear whereas more normal shaped
cylinders are picked correctly.
Regards,
Andreas
