static

Expands a to contain p, initializing invalid bounds to p.

Invalid()

static AABB a3d::AABB::Invalid ( )

static

Returns an invalid box suitable as an empty accumulation seed.

operator|=() [1/2]

AABB & a3d::AABB::operator|=

(

const AABB &

b

)

Expands this box to include b.

operator|=() [2/2]

AABB & a3d::AABB::operator|=

(

const math::vec3 &

p

)

Expands this box to include p.

Union()

static AABB a3d::AABB::Union ( const AABB &  a, const AABB &  b  )

static

Returns the union of a and b, treating invalid bounds as empty.

valid()

(

)

const

Returns whether min is no greater than max on every axis.

Zero()

static AABB a3d::AABB::Zero ( )

static

Returns a zero-size box at the origin.
