Hi Tim,
The mentioned commit breaks scenegraph picking.
For reference take the c172 door handle that opens the dor but never closes it
anymore. Well, except you click at the position where the untransformed door
handle would be.
Also I have some issues with this.
I agree that we should move this into the cull stage. I wanted this also for
some time now. So, thanks for doing this.
But:
I think we should do this in a usual osg::Transform derived class in the two
methods computing the transforms.
That would make picking work again.
That would make osgUtil::CullVisitor find some already pooled RefMatrix without
the need to call new/malloc and delete/free implicitly on each of these nodes.
That would make the nodes work without the EffectCullVisitor and with a plain
osgUtil::CullVisitor. Sure this could be done by just changing the
dynamic_cast to the osgUtil::CullVisitor.
Also osg::Matrix has some methods like {pre,post}Mult{Translate,Scale,Rotate}
which works with O(n^2)~16 operations instead of O(n^3)~64 operations. Ok, the
rotate method saves less.
Greetings
Mathias
