| int NModels | Number of models contained in this file and database |
| Repeated NModels times: | |
| int ModelID int NPoints |
ModelID the same as in ModelNames.txt,
NPoints indicates number of points on the model |
| Repeated NPoints times: | |
| int VertexID int NCorrs |
VertexID vertex id of a point on model ModelID
NCorrs number of points that correspond the point VertexID |
| Repeated NCorrs times: | |
| int ModelID2 int VertexID2 double CorrValue |
ModelID2 index of a model with corresponding point
VertexID2 vertex id on a corresponding model CorrValue correspondence value: f(p1, p2) |
