LIDAR point cloud to mesh visualization
Utilizing Open3D library
cloudlab/ builds test clouds: sample a known mesh (tier 1) or fake a lidar sweep (tier 2). metrics measures point spacing and distance to a mesh.
examples/ runs those two tiers so you can see spacing, anisotropy, and why a random cube cannot be meshed.
tests/ is stdlib unittest for cloudlab; rendering tests stay off unless CLOUDLAB_RENDER_TESTS=1.
