SLIC-Reference : : Distance  

Arguments: location1, location2 Type: int

Returns the distance between location1 and location2

Returns the distance from location1 to location2 (also see SquaredDistance for greater speed if you’re going to use this a lot). Could anyone explain to a mathematical idiot what the difference between Distance() and SquaredDistance() is and why SquaredDistance() is supposed to be faster?

tested   working  

Source:

SFN_ERROR Slic_Distance::Call(SlicArgList *args)
{
	if(args->Count() != 2)
		return SFN_ERROR_NUM_ARGS;

	MapPoint p1, p2;
	if(!args->GetPos(0, p1))
		return SFN_ERROR_TYPE_ARGS;

	if(!args->GetPos(1, p2))
		return SFN_ERROR_TYPE_ARGS;

	m_result.m_int = static_cast
		(sqrt(static_cast(MapPoint::GetSquaredDistance(p1, p2))));
	return SFN_ERROR_OK;
}
