const

getRadius()

double Circle::getRadius

(

)

const

intersect() [1/2]

std::vector< base::Vector2d > Circle::intersect

(

const Circle &

other

)

const

Calculate intersection points of this and other.

Returns

a vector containing the intersections or an empty vector if the circles do not intersect or are identical

intersect() [2/2]

std::vector< base::Vector2d > Circle::intersect

(

const Eigen::ParametrizedLine< double, 2 > &

line

)

const

Calculate intersection points of this and line.

Returns

a vector containing the intersections or an empty vector if the line does not intersect the circle.

Exceptions

std::runtime_error

If the line is invalid

samplePoints()

std::vector<base::Vector2d> numeric::Circle::samplePoints	(	double	start,
		double	end,
		size_t	num
	)		const

Sample points on the circle

Parameters

start	Angle of the first sample (in rad)
end	Angle of the last sample (in rad)
num	Total number of samples (including start and end)

Note

If num == 1, start is returned

Exceptions

std::runtime_error	if num == 0
std::runtime_error	if start == end

setCenter()

void Circle::setCenter

(
