Converting Lidar data from point geometry to Point cloud geometry

Hello everyone ,
i am currently working on Lidar data , i am reading a set of points from a json file and creating vertices based on the coordinates.

here is how the json file containing the Lidar data looks like :  (a bunch of (x,y) set of points)

in order to make use of FME point cloud specific transformers i need to convert these points from point geometry to Point cloud geometry , any idea on how i could do that ?

Thanks in advance
