random_per_voxel: Point Cloud Decimation Algorithm
Description
This functions is made to be used in decimate_points. It implements an algorithm that
creates a 3D grid with a given resolution and filters the point cloud by randomly selecting
n points within each voxel
Usage
random_per_voxel(res = 1, n = 1)
Arguments
res
numeric. The resolution of the voxel grid used to filter the point cloud
