Digitization techniques now makes it possible to produce precise and dense textured 3D point clouds. Therefore, 3D surveys of monuments or archaeological sites can easily reach several billions of points. To ensure a smooth virtual visit and to manipulate these point clouds, we have developed the ESILab software (Enhanced Scan Immersion Lab). Thanks to a dedicated 3D model converter using an octree partitioning of the point cloud and the accessibility of rendering engine parameters, ESILab can load a 3D model containing several billion points in just a few seconds. It also makes it possible to load multiple point clouds, superimpose them and extract slices for relevant comparisons and visualizations. The point clouds of six famous and very large French Gothic monuments were used simultaneously to demonstrate the software’s potential. This software can be shared free of charge upon request right now and will be made available to the public as soon as possible.
