Happy New Year Evgeniy.

So this would calculate area for the surfaces just like my picture?
Assuming a 3D point was used.

Geron's formula works excellent on 3d triangles.
the only problem left is the way we define these triangles.
see my attached drawing.
3d_area_of_ABC + 3d_area_of_CDA = 10488.1
3d_area_of_ABD + 3d_area_of_DBC = 10481.1
