详细描述

A 3D box aligned with the x/y/z axes.
Remarks:
This class represents a simple box which is aligned with the
axes. Internally it only stores 2 points as the extremeties of
the box, one which is the minima of all 3 axes, and the other
which is the maxima of all 3 axes. This class is typically used
for an axis-aligned bounding box (AABB) for collision and
visibility determination.

成员函数说明

◆ contains() [1/2]

boolean AABoxF.contains ( AABoxF other)

Tests whether another box contained by this box.

◆ contains() [2/2]

boolean AABoxF.contains ( Vector3 v)

Tests whether the given point contained by this box.

◆ distance()

float AABoxF.distance ( Vector3 v)

Returns the minimum distance between a given point and any part of the box.

◆ getAllCorners()

Vec3List AABoxF.getAllCorners ( )

Returns a pointer to an array of 8 corner points, useful for
collision vs. non-aligned objects.
Remarks:
If the order of these corners is important, they are as
follows: The 4 points of the minimum Z face (note that
because Ogre uses right-handed coordinates, the minimum Z is
at the 'back' of the box) starting with the minimum point of
all, then anticlockwise around this face (if you are looking
onto the face from outside the box). Then the 4 points of the
maximum Z face, starting with maximum point of all, then
anticlockwise around this face (looking onto the face from
outside the box). Like this:


1-------2
| /|
| / |
5-------4 |
| 0----|--3
| / | /
|/ |/
6-------7

◆ getCenter()

Vector3 AABoxF.getCenter ( )

Gets the centre of the box

◆ getCorner()

Vector3 AABoxF.getCorner ( AABoxF.CornerEnum cornerToGet)

Gets the position of one of the corners

◆ getHalfSize()

Vector3 AABoxF.getHalfSize ( )

Gets the half-size of the box

◆ getMaximum()

Vector3 AABoxF.getMaximum ( )

Gets the maximum corner of the box.

◆ getMinimum()

Vector3 AABoxF.getMinimum ( )

Gets the minimum corner of the box.

◆ getSize()

Vector3 AABoxF.getSize ( )

Gets the size of the box

◆ intersection()

AABoxF AABoxF.intersection ( AABoxF b2)

Calculate the area of intersection of this box and another

◆ intersects() [1/4]

boolean AABoxF.intersects ( AABoxF b2)

Returns whether or not this box intersects another.

◆ intersects() [2/4]

boolean AABoxF.intersects ( PlaneF p)

Tests whether this box intersects a plane.

◆ intersects() [3/4]

boolean AABoxF.intersects ( SphereF s)

Tests whether this box intersects a sphere.

◆ intersects() [4/4]

boolean AABoxF.intersects ( Vector3 v)

Tests whether the vector point is within this box.

◆ isFinite()

boolean AABoxF.isFinite ( )

Returns true if the box is finite.

◆ isInfinite()

boolean AABoxF.isInfinite ( )

Returns true if the box is infinite.

◆ isNull()

boolean AABoxF.isNull ( )

Returns true if the box is null i.e. empty.

◆ matPlusVec3()

Vector3 AABoxF.matPlusVec3 ( Matrix4 m,
Vector3 v )

Transforms the box according to the matrix supplied.
Remarks:
By calling this method you get the axis-aligned box which
surrounds the transformed version of this box. Therefore each
corner of the box is transformed by the matrix, then the
extents are mapped back onto the axes to produce another
AABB. Useful when you have a local AABB for an object which
is then transformed.

◆ merge() [1/2]

void AABoxF.merge ( AABoxF rhs)

Merges the passed in box into the current box. The result is the
box which encompasses both.

◆ merge() [2/2]

void AABoxF.merge ( Vector3 point)

Extends the box to encompass the specified point (if needed).

◆ scale()

void AABoxF.scale ( Vector3 s)

Scales the AABB by the vector given.

◆ setExtents()

void AABoxF.setExtents ( Vector3 min,
Vector3 max )

Sets both minimum and maximum extents at once.

◆ setInfinite()

void AABoxF.setInfinite ( )

Sets the box to 'infinite'

◆ setMaximum()

void AABoxF.setMaximum ( Vector3 vec)

Sets the maximum corner of the box.

◆ setMaximumX()

void AABoxF.setMaximumX ( float x)

Changes one of the components of the maximum corner of the box
used to resize only one dimension of the box

◆ setMinimum()

void AABoxF.setMinimum ( Vector3 vec)

Sets the minimum corner of the box.

◆ setMinimumX()

void AABoxF.setMinimumX ( float x)

Changes one of the components of the minimum corner of the box
used to resize only one dimension of the box

◆ setNull()

void AABoxF.setNull ( )

Sets the box to a 'null' value i.e. not a box.

◆ squaredDistance()

float AABoxF.squaredDistance ( Vector3 v)

Returns the squared minimum distance between a given point and any part of the box.
This is faster than distance since avoiding a squareroot, so use if you can.

◆ transformedCorners()

Vec3List AABoxF.transformedCorners ( Matrix4 matrix)

Get all corners which transformed by given matrix

参数
matrix

◆ volume()

float AABoxF.volume ( )

Calculate the volume of this box
