AABBox

Inherited: None

Description

Bounded volume in space in the form of a rectangular parallelepiped, with a period parallel to the coordinate axes in the world system. When the object rotates, the AABB changes its dimensions, but it always remains oriented along the coordinate axes. Axis Aligned Bounding Box represented by center of box and extent.

Methods Description

AABBox::AABBox ()

Constructs an bounding box with center (0, 0, 0) and extent (0.5, 0.5, 0.5).

---

AABBox::AABBox (Vector3 & center, Vector3 & extent)

Constructs a bounding box with center and extent.

---

void AABBox::box (Vector3 & min, Vector3 & max) const

Returns min and max points of bounding box as output arguments.

See also setBox().

---

void AABBox::encapsulate (AABBox & aabb)

Grow the AABBox to encapsulate the aabb.

---

void AABBox::encapsulate (Vector3 & position, areal radius = 0.0f)

Grow the AABBox to encapsulate a spehere with position and radius.

---

bool AABBox::intersect (Plane & plane) const

Returns true if this bounding box intersects the given plane; otherwise returns false.

---

bool AABBox::intersect (Vector3 & position, areal radius) const

Returns true if this bounding box intersects the given sphere at position and radius; otherwise returns false.

---

bool AABBox::isValid () const

Returns true in case of AABBox is valid; otherwise returns false.

---

void AABBox::setBox (Vector3 & min, Vector3 & max)

Set current bounding box by min and max points.

See also box().

---

void AABBox::setBox (Vector3 * points, uint32_t number)

const AABBox AABBox::operator* (Matrix3 & matrix) const

Returns a copy of this box, multiplied by the given rotation matrix.

---

const AABBox AABBox::operator* (Matrix4 & matrix) const

Returns a copy of this box, multiplied by the given transform matrix.

---

const AABBox AABBox::operator* (Quaternion & quaternion) const

Returns a copy of this box, multiplied by the given quaternion.

---

const AABBox AABBox::operator* (Vector3 & vector) const

Returns a copy of this box, multiplied by the given vector.

---

AABBox & AABBox::operator*= (Matrix3 & matrix)
