The mathematical result of the integration is a *N*-by-4 matrix, where each line contains the 3D coordinates of a 3D point plus the associated temperature (or, if no temperature is associated, a *NaN* value). This matrix is visualized in Matlab by assigning to the point subset with an associated temperature a particular colormap, whereas a different color is assigned to the points with no temperature associated.

Figure 7 shows an outline of the workflow in the case of the integration of multiple thermograms on the same point cloud.
