Description 描述

Represents an axis aligned bounding box.

表示一个轴对齐边界盒。

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 and extents, or alternatively by min and max points.

一个轴对齐边界盒，或简称AABB，是一个对齐坐标轴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和extents定义，或者由min和max点定义。

Bounds is used by Collider.bounds, Mesh.bounds and Renderer.bounds.

Bounds用于Collider.bounds、Mesh.bounds 和 Renderer.bounds

Variables 变量

center	The center of the bounding box. 边界盒的中心。
extents	The extents of the box. This is always half of the size. 边界框的实际范围。这个总是size的一半。
max	The maximal point of the box. This is always equal to center+extents. 边界盒的最大点，这个总是等于center + extents。
min	The minimal point of the box. This is always equal to center-extents. 边界盒的最小点，这个总是等于center-extents。
size	The total size of the box. This is always twice as large as the extents. 边界盒的总大小。这个总是extents的两倍大。

Constructors 构造器

Bounds

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，创建一个新的边界盒。边界盒的extents将是给定size的一半。

Public Functions 共有函数

ClosestPoint	The closest point on the bounding box. 边界盒上最近的点。
Contains	Is point contained in the bounding box? 这个点包含在边界盒中么？
Encapsulate	Grows the Bounds to include the point. 生长该边界框以包含这个点。
Expand	Expand the bounds by increasing its size by amount along each side. 通过amount沿着每条边增加边界盒的size来扩展边界盒。
IntersectRay	Does ray intersect this bounding box? 射线与该边界盒相交么？
Intersects	Does another bounding box intersect with this bounding box? 该边界框是否和另一个边界框相交？
SetMinMax	Sets the bounds to the min and max value of the box. 设置边界盒的最小和最大值。
SqrDistance	The smallest squared distance between the point and this bounding box. 点和该边界盒之间的最小平方距离。
ToString	Returns a nicely formatted string for the bounds. 返回边界盒已格式化好的字符串。
