A short project for downsampling point clouds using an octree.
After cloning this repo, run $ make in the directory. This should produce an executable named downsampler.
Simpy run the executable in the terminal, for example $ ./downsampler. It will look for input.csv in the current directory and downsample it to produce output.csv.
Above shows a point cloud of a building with arches before and after being downsampled with my downsampler. It was about 70%+ points lost for the 10 meter boundary. Data is from here: LINK
