Point Cloud Underlay

Field notes

The interface works from LAS or LAZ scans and exposes unusually detailed controls for source units, cut height and depth, pixels per foot, story height, floor sensitivity, and detection method. Its preview generates four directional elevations plus eight sections, while wall snapping uses PCA line growing and vector export keeps longer wall segments before merging near-collinear runs. The page also identifies WebAssembly workers for large scans and offers GPU or CPU processing.
