Dear All,
Mainly I have 2 questions, both are to achieve the comprehensive selection task
in OSG.
#1 - How to draw a rectangle, polygonal, circle, lasso etc.. selection
rubber?#2 - How to configure OSG to implement that selection defined at the
first step?
For selection part OSG Beginners book suggest to use
osgUtil::PolytopeIntersector for regional selection, but doesn't give any clue
on how to draw the rubber or is it comes as an intrinsic feature of
sgUtil::PolytopeIntersector when you create it with WINDOW parameter set on.
I also studied the osgkeyboardmouse.cpp example, but I couldn't find any
visible difference when I switch from LineSegmentInteresect to
PolytopeIntersector, while I was expecting to see the HUD window rubber to be
drawn and objects falling into that rectangle to be selected.
Your guidance will be appreciated!
Regards,
