Load a series of measurements of the same surface and combine them for 4D analysis – load 3D measurements of the same surface made at different times or under different environmental conditions – combine the measurements into a series with 4 dimensions x, y, z and t, where t is time, temperature, pressure, magnetic field or another fourth dimension (linear or non-linear) – add a new measurement to the series or delete an old measurement at any time – ensure point to point matching using automatic and manual shifting tools – apply preprocessing operators simultaneously to every 3D measurement in the series.

Visualize surface, profile and point evolution – display all of the surfaces in the series in a grid or walk through them one by one – display an animated view of the surfaces as they change with respect to time or another dimension – fly over the series, see the surface changing and record a movie for presentations – extract a profile between points and see how it evolves – extract a transverse profile showing changes in the height of a single point on the surface.

Generate statistics and highlight areas of preponderant change – generate statistics showing how one or more parameters evolve as the surface changes: parameter tables (including min, max, standard deviation), control charts, scatter plots, histograms – highlight areas of preponderant change using the Karhunen-Loève transform (principal component analysis).
