strategy::distance::projected_point

Strategy for distance point to segment.

Description

Calculates distance using projected-point method, and (optionally) Pythagoras

Synopsis

template<typename CalculationType, typename Strategy>
class strategy::distance::projected_point
{
  // ...
};

Template parameter(s)

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 Strategy

pythagoras<CalculationType>

underlying point-point distance strategy
