TINGenerator

From fmepedia

TINGenerator is a Workbench Transformer.

Generates a Delaunay surface model and outputs the defining Triangulated Irregular Network (TIN). The TIN is output as both Triangles and TIN Edges.

The underlying surface is built using the surface tolerance as specified by the tolerance parameter. This should be set to the larger of the accuracy of the elevation data being input and the accuracy of the output elevation that is required. A higher surface tolerance results in a less detailed (less accurate) TIN.

The same functionality is offered by the SurfaceModeller.
