Constructor Detail

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 cone

direction - the direction of the cone

spreadAngle - the spread angle of the cone in radians

Method Detail

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 cone

direction - the direction of the cone

spreadAngle - 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 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
