The reconstructed 3-D points are available as Matlab® 4.2c binary datafiles (mat-files). No connectivity among the points is represented.
Each datafile consists of a list of partial reconstructions registered in the same room global coordinate frame F3 for a given partial scan (a - h). One item in a list represents one reconstruction (0 - 4) in the scan, see The Mapping between Coordinate Systems. To access the lists, we provide a Matlab®function litem.
A partial reconstruction comprises a vector of reconstructed 3D points [x,y,z] and a vector of colors [r,g,b], one color entry per 3-D point. Please note that the reconstruction for any given view is available in just one partial scan and is not repeated in other scans. For instance, the view 1 in scan c is not present in any of the d, g, h datasets in both the Segment A and C. See the table below for what views are covered in which scan (in parentheses).
