Data Structures
struct	cross_prod_impl< PointT, 1 >
	Implementation of the cross product calculation in 1d for compatibility. Returns the zero-vector. More...

Namespaces
namespace	viennagrid
	The main ViennaGrid namespace. Most user functionality resides directly in this namespace rather than in sub-namespaces.
namespace	viennagrid::detail
	Namespace for implementation details. Not intended to be used directly by a library user.
Functions
template<typename PointT1 , typename PointT2 >
PointT1	cross_prod (PointT1 const &v1, PointT2 const &v2)
	Returns the cross product of two vectors. If the vectors have one or two components only, the zero vector is returned.
template<typename PointT1 , typename PointT2 , typename CSystem1 , typename CSystem2 >
PointT1	cross_prod_impl (PointT1 const &p1, PointT2 const &p2, CSystem1 const &, CSystem2 const &)
	Dispatched cross product function having information about the coordinate systems. Transforms to Cartesian coordinates and forwards to calculation.
template<typename PointT1 , typename PointT2 , int d>
PointT1	cross_prod_impl (PointT1 const &p1, PointT2 const &p2, cartesian_cs< d >, cartesian_cs< d >)
	Dispatched cross product function having information about the coordinate systems. Points are already in Cartesian coordinates, thus forwarding to the worker function directly.
