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

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).
