segment

Documentation

Overview

Package segment defines a truncated cone-like object whose bottom is defined by a characteristic line segment (instead of a point). This object also has a characteristic "turning radius", which defines the sharpness of the curve from the bottom line segment to the edges.

L \     / R
   \___/
     S

As with the case of the point-defined cone, we define tangential lines from the VO to the left and right circles of at the ends of the line segment S.

Types

type S

type S struct {
	// contains filtered or unexported fields
}

func New

func New(s segment.S, p vector.V, radius float64) *S

func (S) L

func (s S) L() line.L

L calculates the left vector of the tangent line from the agent position to the base of the truncated line segment.

N.B.: ℓ is always directed away from the agent.

func (S) R

func (s S) R() line.L

func (S) S

func (s S) S() segment.S

S returns the base of line segment VO. Depending on the setup, this segment may differ from the constructor input segment.
