Thanks Calvin, In the QGIS version I’m using, there is Nearest Neighbour algorithm. Natural Neighbour is smth else, and it seems the easiest way to have it for me is WhiteBox Tools plugin.

Under Raster - Rasterizing, there is a Natural Neighbour algorithm. I have not used it, but I have used the Inverse Distance Weighted algorithm for magnetometry data which in essence does something like what you are wanting to do.

Is there any way to replicate it in QGIS? https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-analyst/how-natural-neighbor-works.htm Alternatively, what would be a way to constructing DTM from points, preserving the original points in respective pixels?
