Plane 平面

Struct

Representation of planes.

表示平面。

A plane is defined by a normal vector and distance from the origin to the plane.

一个平面是由一个向量法线和从原点到平面的距离定义的。

Variables变量

• normal
  Normal vector of the plane.
  平面的法线向量。
• distance
  Distance from the origin to the plane.
  从原点到平面的距离。

Constructors构造器

• Plane
  Creates a plane.
  创建一个平面。

Functions函数

• SetNormalAndPosition
  Sets a plane using a point that lies within it plus a normal to orient it (note that the normal must be a normalised vector).
  设置平面上的点和法线的朝向（注意法线必须是规范化的向量）。
• Set3Points
  Sets a plane using three points that lie within it. The points go around clockwise as you look down on the top surface of the plane.
  使用三个点来设置平面。点环绕顺时针方向，正如看到的平面的顶面。
• GetDistanceToPoint
  Distance from plane to point.
  从平面到点的距离。
• GetSide
  Is a point on the positive side of the plane?
  一个点在平面的正面么？
• SameSide
  Are two points on the same side of the plane?
  两个点在平面的同一侧么。
• Raycast
  Intersects a ray with the plane.
  一条射线和平面相交。
