      Constructor Description
      PlaneCPtr()
      Default constructor yielding a NULL-pointer.
      PlaneCPtr​(long cPtr, boolean cMemoryOwn)  
      PlaneCPtr​(Plane ptr)
      Do not take ownership of ptr.

      ptr can be null.

      The constructor is implicit on purpose.

        Do not take ownership of ptr.

        ptr can be null.

        The constructor is implicit on purpose.

    • Method Detail

      • getCPtr

        public static long getCPtr​(PlaneCPtr obj)

      • delete

        public void delete()

      • deref

        public Plane deref()
        The pointer stored in the object.

      • __ref__

        public Plane __ref__()
        Dereferencing operator.

      • getDeref

        public Plane getDeref()
        Member access operator.

      • equals

        public boolean equals​(Plane p)

      • isShared

        public boolean isShared()
        check if this Ptr has shared ownership or none
        ownership
        Returns:
        true if Ptr has shared ownership, false if it has no ownership.

      • isNull

        public boolean isNull()
        checks if the pointer is null
        Returns:
        Returns true if the pointer is null

      • distance

        public double distance​(Vector3D point)
        Calculates the shortest distance from point to plane.

        The distance includes the sign s.t. a negative distance corresponds to point
        being behind the plane and a positive distance in front of the plane.

        Parameters:
        point -

      • distance

        public double distance​(Plane plane)
        Default metric for computing the difference between 2 planes
        Parameters:
        plane - [in]

      • intersection

        public Vector3D intersection​(Vector3D p1,
                             Vector3D p2)
        Calculates the intersection between the line and plane.

        The line defined by p1 and p2 is considered infinitely long.
        Throws a rw::core::Exception if the line is parallel to the plane.

        Parameters:
        p1 - [in] point 1 on the line
        p2 - [in] point 2 on the line

      • createMesh

        public TriMeshPtr createMesh​(int resolution)

      • createMesh

        public TriMeshPtr createMesh​(int resolution,
                             double size)
        Create a triangle mesh representing the plane.

        Provides the posibility to specify the size of the plan.
        Parameters:
        resolution - [in] Resolution of the mesh (not applicable for a plane)
        size - [in] Size of the plane.
