Compare a building IFC with its matching colour point cloud to inspect façades, balconies and roof edges.
The pair is example-no-1.ifc and example-no-1.laz from the xeokit examples repository. The scan has 9,265,546 points, including surrounding ground and parked cars. Both files use shared local metre coordinates. The IFC bounds are approximately X 705.512–793.626 m, Y 84.995–109.509 m, Z 82.083–106.356 m, inside the scan bounds X 694.785–802.589 m, Y 78.559–114.389 m, Z 78.515–106.567 m. Rooflines, façades and balconies visually overlap without a translation, rotation or scale correction. This visual check does not certify survey accuracy or model deviations.
The page checks each source’s byte length and SHA-256 before passing the original Blob to viewer.add(name, blob). It loads the IFC first, then the LAZ, retaining successful imports when a later download needs a retry. The SDK handles parsing, point-cloud storage, visibility, sections and navigation. Neither file declares a projected CRS, so the example adds no geographic location or map conversion. The IFC is about 30 MB and the LAZ about 91 MB.

Both files are downloaded directly from the official xeokit/examples GitHub repository, pinned to revision eedeb4dca756d56c7703b312daff22fa31643fef: example-no-1.ifc and example-no-1.laz. The repository’s model and point-cloud alignment example uses the same pair.
