[osg-users] Cast Drawable to ShapeDrawable

[Christian Kunz]

Hi everyone,

I want to pick a geometry object in 3D-Space, e.g. a cylinder.

I use a LineSegmentIntersector to do so. Actually this is working fine. I can call 


Code:
result.drawable.get();



on 


Code:
const osgUtil::LineSegmentIntersector::Intersection& result = *(intersector->getIntersections().begin());



to get an osg::Drawable object:


Code:
osg::Drawable *tempDraw = result.drawable.get();



This gives me an osg::Drawable object. But the object is actually an osg::ShapeDrawable.

How can I cast it the right way to an osg::ShapeDrawable? Do I need to use a dynamic_cast?


... 

Thank you!

Cheers,
Christian
