Constructor Detail

PickCylinderRay

public PickCylinderRay()

Constructs an empty PickCylinderRay. The origin and direction of the cylindrical ray are initialized to (0,0,0). The radius is initialized to 0.

PickCylinderRay

public PickCylinderRay(Point3d origin,
               Vector3d direction,
               double radius)

Constructs an infinite cylindrical ray pick shape from the specified parameters.

Parameters:

origin - the origin of the cylindrical ray.

direction - the direction of the cylindrical ray.

radius - the radius of the cylindrical ray.

Method Detail

set

public void set(Point3d origin,
       Vector3d direction,
       double radius)

Sets the parameters of this PickCylinderRay to the specified values.

Parameters:

origin - the origin of the cylindrical ray.

direction - the direction of the cylindrical ray.

radius - the radius of the cylindrical ray.

intersect

final boolean intersect(Bounds bounds,
                Point4d pickPos)

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

Specified by:

intersect in class PickCylinder

Parameters:

bounds - the bounds object to check

pickPos - the location of the point of intersection (not used for method. Provided for compatibility).

transform

PickShape transform(Transform3D t3d)

Specified by:

transform in class PickShape
