Bounds 包围盒

# Bounds 包围盒

Struct

Represents an axis aligned bounding box.

表示一个轴对齐包围盒。

An axis-aligned bounding box, or AABB for short, is a box aligned with
coordinate axes and fully enclosing some object. Because the box is never
rotated with respect to the axes, it can be defined by just its [center](Bounds.center.html) and [extents](Bounds.extents.html), or alternatively by [min](Bounds.min.html) and [max](Bounds.max.html) points.

一个轴对齐包围盒，或 AABB 的简称，是一个坐标轴对齐的盒子并完全包围某些物体。由于这个盒子不会相对于轴旋转，它只可以通过 [center](Bounds.center.html) 和 [extents](Bounds.extents.html) 定义，或者由 [min](Bounds.min.html) 和 [max](Bounds.max.html) 点定义。

包围盒用于 [Collider.bounds](../Collider/Collider.bounds.html), [Mesh.bounds](../Mesh/Mesh.bounds.html), [Renderer.bounds](../Renderer/Renderer.bounds.html).

### Variables**变量**

* [center](Bounds.center.html)
  The center of the bounding box.
  包围盒的中心。
* [size](Bounds.size.html)
  The total size of the box. This is always twice as large as
  the extents.
  包围和的总大小。这个总是 [extents](Bounds.extents.html) 的两倍大。
* [extents](Bounds.extents.html)
  The extents of the box. This is always half of the
  size.
  包围盒的广度。这个总是 [size](Bounds.size.html)[](Bounds.extents.html)的一半。
* [min](Bounds.min.html)
  The minimal point of the box. This is always equal to
  center-extents.
  包围盒的最小点，这个总是等于 center-extents。
* [max](Bounds.max.html)
  The maximal point of the box. This is always equal to
  center+extents.
  包围盒的最大点，这个总是等于 center + extents。

### Constructors**构造器**

* [Bounds](Bounds.Bounds.html)
  Creates new Bounds with a given center and total size.
  Bound extents will be half the given size.
  用给定的中心和总大小，创建一个新的包围盒。包围盒 [extents](Bounds.extents.html) 将是给定 size 的一半。

### Functions**函数**

* [SetMinMax](Bounds.SetMinMax.html)
  Sets the bounds to the min and max value of the
  box.
  设置包围盒的最小和最大值。
* [Encapsulate](Bounds.Encapsulate.html)
  Grows the Bounds to include the point.
  增大包围盒以包含这个点。
* [Expand](Bounds.Expand.html)
  Expand the bounds by increasing its size by amount along
  each side.
  通过增加 amount 的大小沿着每条边扩大包围盒。
* [Intersects](Bounds.Intersects.html)
  Does another bounding box intersect with this bounding
  box?
  这个包围盒是否和另一个包围盒相交？
* [Contains](Bounds.Contains.html)
  Is point contained in the bounding box?
  这个点包含在包含盒中么？
* [SqrDistance](Bounds.SqrDistance.html)
  The smallest squared distance between the point and this
  bounding box.
  点和这个包围盒之间的最小平方距离。
* [IntersectRay](Bounds.IntersectRay.html)
  Does ray intersect this bounding box?
  射线与这个包围盒相交么？
* [ToString](Bounds.ToString.html)
  Returns a nicely formatted string for the
  bounds.
  返回包围盒格式化好的字符串。
