First compressed mesh made using LiDAR scanned point cloud of Ian Smith’s Studio.
We’ve found it a challenge to recreate the quality of the original scans in the compressed 3D object. First we exported the scans as an E57 point cloud from the initial AutoDesk Recap project that was deposited with use. We then computed the normals for the point cloud using CloudCompare, and used the PoissonRecon extension to create the mesh object. Whilst there are still a lot of unwanted artefacts on the object, it is a much better result than early attempts which didn’t have normal computed to the same level. This mesh object was around 4gb in size, we then decimated the mesh using Agisoft Metashape to condense it for upload, unfortunately we lost a lot more detail here too.
