[osg-users] Pb with PlaneIntersector

[a.lagnier]

Hi,

osgUtil::PlaneIntersector seems to return some bad polylines. This polylines 
belong to parallel planes!! It's very strange.
Any idea of what happen?


Thanks in advance

[osg-users] LineSegmentIntersector and line width

[a.lagnier]

Hi,

I'm using osgUtil::LinesegmentIntersector to pick objects from my scene.
It works all fine except Geode containing line geometry (with LineWidth 
stateset). But, I want to pick somes thick lines, how can I do?

Thanks in advance!
