Detailed Description

template<int Dim>
class Go::BaryCoordSystem< Dim >

Encapsulates a barycentric coordinatesystem.

It is designed to work in any dimension, but at the time of writing, only dimension 2 and 3 is supported by the functions in the included header "Volumes.h"

You specify the dimension with a template parameter:

BaryCoordSystem<2> bc(corner_pointer);

... or by using the supplied typedefs:

BaryCoordSystem2D bc(corner_pointer);

This file also contains the small function called triangle_area_signed().
