Interpolate point on a cartesian segment.
template<typename CalculationType, typename DistanceStrategy> class strategy::line_interpolate::cartesian { // ... };
Parameter 
Default 
Description 

typename CalculationType 
void 
numeric type for calculation (e.g. high precision); if void then it is extracted automatically from the coordinate type and (if necessary) promoted to floating point 
typename DistanceStrategy 
distance::pythagoras<CalculationType> 
The underlying pointpoint distance strategy 
Function 
Description 
Parameters 
Returns 

distance_pp_strategy::type get_distance_pp_strategy()
