Hi everyone
My task/problem is the follwoing:
I got pointclouds from lidar scans. Each scan is like a picture you could say (scanner is not moving, just take 5 seconds scan time and gives me the pointcloud).

Render an image of the scan from the origin (scanner) with the depth values (the radius of xyzcoordinates). Could be seen as computing the distance to all points and project these values on a plane (normal facing into the viewing direction). I tried several things and searched for solutions but couldn’t find one.

This task is a bit more advanced. As example I would take the Stanford Bunny as a pointcloud. Now I set an arbitrary point as my “camera”. I want to do the same thing as in 1). Calculate the distance from all other points to the camera point. Project the distance values on a plane with the normal facing into the direction of the center of the bounding box of the pointcloud. (Not considering “hidden” points at first)
I would appreciate any help, solutions or hints in the right direction
