I have a question relating to 3D point cloud. I hope you can help me get answer. Given an 3D point cloud (i obtained it by uniform sampling from a big point cloud), I would like to make an undirected graph consisting of nodes as the 3D points, edges as links between two adjacent nodes. What are steps that i need to follow to implement this graph? Or are there any algorithms for this problem ? Is there any available code you can share for me?
Thank you so much. Looking forward to your reply. Toan
