# [Camera](Camera.html).WorldToScreenPoint 世界转屏幕位置

function *WorldToScreenPoint* (*position* : [Vector3](../Vector3/Vector3.html)) : [Vector3](../Vector3/Vector3.html)

*Description* 描述

Transforms position from world space into screen space.

从世界空间到屏幕空间变换位置。

Screenspace is defined in pixels. The bottom-left of the screen is (0,0); the
right-top is ([pixelWidth](Camera.pixelWidth.html),[pixelHeight](Camera.pixelHeight.html)). The z position is in world
units from the camera.

屏幕空间以像素定义，屏幕左下为 0,0，右上是([pixelWidth](Camera.pixelWidth.html),[pixelHeight](Camera.pixelHeight.html))，Z 的位置是以世界单位衡量的到相机的距离。
