[anhtuduong]

We need to visualize point clouds.
Data type: PointCloud2

I have extracted point cloud of 1 object: point_cloud.txt

Note that: point cloud saved to this file is a list of tuples. Where every tuple is the coordinate x,y,z of a single point.
[ (x,y,z), (x,y,z),...]

Please find a way to visualize it!
