Few words on these specific data sets. All the data consists of triangles only. Each triangle looks as follows:

[POLYGON [PLANE -0.2142377 0.93292164 0.2894121 -0.8252709] 3 [[HSqrCurv 0.821374] [KCurv -3.39314] [uvvals "0.25 0.25"] 2.21630859375 1.2895751953125 0.33521484375] [[HSqrCurv 0.151514] [KCurv -2.3828] [uvvals "0.25 0"] 2.1796875 1.38515625 0] [[HSqrCurv 0.124987] [KCurv -0.701459] [uvvals "0 0"] 1.7 1.275 0] ]

- The "[PLANE ... ]" clause defines the plane (and the normal of the polygon, pointing inside).
- The '3' at the end of the line with the POLYGON keyword states that three vertices are to be expected (always the case for these data sets).
- Each vertex has the forms of '[[attribute_1 ... ] ... [attribute_N ... ] x y z]'
- The 'HSqrCurv' attribute denotes the mean curvature square value of the surface at that vertex.
- The 'KCurv' attribute denotes the total (Gaussian) curvature value of the surface at that vertex.
- The 'uvvals' attribute provides denotes UV parametric values of the original surface at that location.
