Camera.WorldToViewportPoint 世界转视窗位置


function WorldToViewportPoint (position : Vector3) : Vector3

Description描述

Transforms position from world space into viewport space.

从世界空间到视窗空间的变换位置。

Viewport space is normalized and relative to the camera. The bottom-left of the camera is  (0,0); the top-right is (1,1). The z position is in world units from the camera.

视口空间是归一化的并相对于相机的。相机的左下为（0,0）；右上是（1,1），Z的位置是以世界单位衡量的到相机的距离。
