Detailed Description

Euclidean space representation of polygon with height info. This extends Vect3 (temporarily) in order to take advantage to polymorphism of detection algorithms. If treated as a normal Vect3 point, this ignores the polygon information. Only functions that are aware of Poly3Ds will have access to its full definition.

Member Function Documentation

averagePoint()

Vect3 larcfm::Poly3D::averagePoint

(

)

const

Return the average of all vertices. Note this is not the same as the centroid, and will be weighted towards concentrations of vertices instead of concentrations of area/mass. This will, however, have the nice property of having a constant linear velocity between two polygons, even if they morph shape.

Returns

point

contains()

bool larcfm::Poly3D::contains

(

const Vect3 &

v

)

const

This uses a standard raycasting check for point inclusion. It does not explicitly use ACCoRD detection algorithms.

Parameters

v

vector

Returns

true if contains

contains2D()

bool larcfm::Poly3D::contains2D

(

const Vect2 &

v

)

const

This uses a standard raycasting check for point inclusion. It does not explicitly use ACCoRD detection algorithms.

Parameters

v

vector

Returns

true if contains

getBoundingRectangle()

BoundingRectangle larcfm::Poly3D::getBoundingRectangle

(

)

const

Creates a bounding rectangle from the vertices of the polygon.

Returns

distance

isConvex()

bool larcfm::Poly3D::isConvex

(

)

const

Returns true if this polygon is convex

Returns

true, if convex

remove()

void larcfm::Poly3D::remove

(

int

n

)

Remove a point from this SimplePolyNew.

Parameters

n	Index (in order added) of the point to be removed.

reverseOrder()

Poly3D larcfm::Poly3D::reverseOrder

(

)

const

Reverses the order of the vertices

Returns

polygon
