osgUtil::LineSegmentIntersector::LineSegmentIntersector | ( | const osg::Vec3d & | start, |
const osg::Vec3d & | end | ||

Construct a LineSegmentIntersector the runs between the specified start and end points in MODEL coordinates.
osgUtil::LineSegmentIntersector::LineSegmentIntersector | ( | CoordinateFrame | cf, |
const osg::Vec3d & | start, | ||
const osg::Vec3d & | end | ||

Construct a LineSegmentIntersector the runs between the specified start and end points in the specified coordinate frame.

) |
Convenience constructor for supporting picking in WINDOW, or PROJECTION coordinates In WINDOW coordinates creates a start value of (x,y,0) and end value of (x,y,1). In PROJECTION coordinates (clip space cube) creates a start value of (x,y,-1) and end value of (x,y,1). In VIEW and MODEL coordinates creates a start value of (x,y,0) and end value of (x,y,1).
