A RPlidar A1M8 is a 2D lidar, meaning that it can only get data about its surroundings from a 2D perspective. 3D lidars can get info from their surroundings in a 3D perspective. To make a 2D lidar into a 3D lidar you would need to spin the 2D lidar around very fast on its roll axis and know the position of the 2D lidar on the roll axis. If you can combine the regular 2D lidar data (The distance from the object and the yaw angle of the lidar) and where the roll angle of the lidar you can get data in a 3D perspective or what is known as a pointcloud. (Doing what I described is not recomended)

There is actually a package that helps converting 2D laser scan.
