3D processing prepares geometric observations for inspection, alignment, and downstream modeling. Open3D demonstrates point-cloud visualization, voxel downsampling, normal estimation, segmentation, and geometric measurements. Preserve the original geometry so processing effects remain inspectable.
In a construction or perception exercise, record units and coordinate frames before combining scans. Downsampling reduces point count but can remove important detail. Compare processed data with the original, and report alignment errors or missing surfaces instead of treating a clean visualization as complete evidence.
Geometries can look plausible while being mis-scaled or misaligned. Explicit frames and units make transformations and measurements interpretable.
