Hi !
I m trying to detect wich object is selected with
LineSegmentIntersector . I m using the example osgpick to help.
The problem is that I can only see where the line is intersected but I
want to execute some command only if a test objet is intersected.
For example if I have two spheres A and B .
How do I know if I m touching only the A sphere ?
The osgpick code demonstrates how to get all kinds of information from
the Intersection objects in the
osgUtil::LineSegmentIntersector::Intersections list. You can get the
local and world coordinates, the model matrix, the drawable object, the
primitive index of the drawable, and even the node path traversed
through the scene to get to the drawable. It's all in the Intersection
object.
