Detailed Description

An axis-aligned bounding box.

Provides convenience functions for creating a bounding box (adding a single point, merging boxes), as well as for testing containment/intersection.

addPointToBox()

void iAAABB::addPointToBox

(

iAVec3d const &

pt

)

add a point that should fit into the bounding box; if the current box does not contain this point, it is enlarged

contains()

bool iAAABB::contains

(

iAVec3d const &

pt

)

const

return true if the given point is contained within the bounding box

intersects()

bool iAAABB::intersects

(

iAAABB const &

other

)

const

return true if the given other bounding box has intersecting space with this

maxCorner()

iAVec3d const & iAAABB::maxCorner

(

)

const

Retrieve the maximum of each of the 3 coordinates as point vector.

merge()

void iAAABB::merge

(

iAAABB const &

other

)

merge another bounding box to this one, enlarging it if necessary

minCorner()

(

)

const
