PickConeRay
public PickConeRay()
- Constructs an empty PickConeRay.
The origin and direction of the cone are
initialized to (0,0,0). The spread angle is initialized
to
PI/64
radians.
PickConeRay
public PickConeRay(Point3d origin,
Vector3d direction,
double spreadAngle)
- Constructs an infinite cone pick shape from the specified
parameters.
- Parameters:
origin
- the origin of the conedirection
- the direction of the conespreadAngle
- the spread angle of the cone in radians
set
public void set(Point3d origin,
Vector3d direction,
double spreadAngle)
- Sets the parameters of this PickCone to the specified values.
- Parameters:
origin
- the origin of the conedirection
- the direction of the conespreadAngle
- the spread angle of the cone in radians
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 PickCone
- Parameters:
bounds
- the bounds object to checkpickPos
- 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
