How to display the pointcloud?

[lyy-1997-hub]

when I run the "./demo [*.pcd]" in the directory of cuda-icp, just got the result: GPU has cuda devices: 1 ----device id: 0 info---- GPU : Xavier Capbility: 7.2 Global memory: 31918MB Const memory: 64KB SM in a block: 48KB warp size: 32 threads in a block: 1024 block dim: (1024,1024,64) grid dim: (2147483647,65535,65535)

so,I really want to know how to display the result,just like https://developer.nvidia.com/zh-cn/blog/cuda-pcl-1-0-jetson/

There will be three *.pcd: cuda.pcd, ICP.pcd, GICP.pcd in the same dir after "./demo". You can use the command below to install "pcl_viewer" which can be used to show *.pcd sudo apt-get install pcl-tools
