5. def cartesianToSpherical(p: Point3D): Point3D

   

   Convert a Point3D with cartesian coordinates in a Point3D with spherical coordinates.

   Convert a Point3D with cartesian coordinates in a Point3D with spherical coordinates.

   p

   : (Point3D) Input Point3D with cartesian coordinates.

   returns

7. def dec2theta(dec: Double, inputInRadian: Boolean = false): Double

   

   Convert declination into theta

   Convert declination into theta

   dec

   : (Double) declination coordinate in degree

   inputInRadian

   : (Boolean) If true, assume the input is in radian. Otherwise make the conversion deg2rad. Default is false.

12. def getSampleSize(totalNumRecords: Long, numPartitions: Int): Int

    

    Get sample size to be taken from the RDD.

    Get sample size to be taken from the RDD. This is required in order to avoid the drive Out of Memory (OOM) when the the data size in itself is very large. The min 5000 totalNumRecords bound is added in order to ensure a sufficiently deep Octree construction.

    Convert right ascension into phi

    ra

    : (Double) RA coordinate in degree

    inputInRadian

    : (Boolean) If true, assume the input is in radian. Otherwise make the conversion deg2rad. Default is false.

    returns

    (Double) phi coordinate in radian

19. def sphericalToCartesian(p: Point3D): Point3D

    

    Convert a Point3D with spherical coordinates in a Point3D with cartesian coordinates.

    Convert a Point3D with spherical coordinates in a Point3D with cartesian coordinates.

    p

    : (Point3D) Input Point3D with spherical coordinates.

    returns

    (Point3D) The same point but with cartesian coordinates.

21. def takeOrdered[T <: Shape3D](rdd: RDD[T], num: Int, queryObject: T, unique: Boolean = false)(ord: Ordering[T])(implicit arg0: ClassTag[T]): Array[T]

    

    Custom takeOrdered function to take unique top k elements from the RDD based on the priority of the elements relative to the queryObject defined by the custom Ordering.

    Custom takeOrdered function to take unique top k elements from the RDD based on the priority of the elements relative to the queryObject defined by the custom Ordering. In case, the unique elements are not needed, fallback to using the RDD's takeOrdered function.

    rdd

    RDD from which the elements are to be taken

    num

    number of elements to be taken from the RDD

    queryObject

    elements relative to which the priority is to be defined

    unique

    true/false based on whether unique elements should be returned or not

    ord

    custom Ordering based on which the top k elements are to be taken

    returns

    array of top k elements based on the Ordering relative to the queryObject from the input RDD
