Constructor Detail

PickSegment

public PickSegment()

Constructs an empty PickSegment. The start and end points of the line segment are initialized to (0,0,0).

PickSegment

public PickSegment(Point3d start,
           Point3d end)

Constructs a line segment pick shape from the specified parameters.

Parameters:

start - the start point of the line segment.

end - the end point of the line segment.

Method Detail

set

public void set(Point3d start,
       Point3d end)

Sets the parameters of this PickSegment to the specified values.

Parameters:

start - the start point of the line segment.

end - the end point of the line segment.

get

public void get(Point3d start,
       Point3d end)

Gets the parameters from this PickSegment.

Parameters:

start - the Point3d object into which the start point will be copied.

end - the Point3d object into which the end point will be copied.

intersect

final boolean intersect(Bounds bounds,
                Point4d pickPos)

Return true if shape intersect with bounds. The point of intersection is stored in pickPos.
