Computing the 3D Surface.

This tool allows you to compute the 3D Surface of a DTM as well as the projected 2D Surface.

At the command prompt, FlashMNT displays :

>> Select the 3D Faces :

Select the desired objects then validate. The result is displayed on the screen.

===============================
>> 2D Surface : 8473.267
>> 3D Surface : 9442.107
===============================

Remarks : The surface computation can only be performed on triangular 3D faces. Do your computations on a triangulation, not on a mesh.
