function ViewportToWorldPoint (position : Vector3) : Vector3
Description描述
Transforms position from viewport space into world space.
从视窗空间到世界空间的变换位置。
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。
Note that it transforms a x-y screen position, into a x-y-z position in 3D space.
请注意它是变换一个x-y屏幕位置到一个3D空间的x-y-z位置。
You provide the function with a vector where the x-y components of the vector are the screen coordinates and the z component is the distance of the resulting plane from the camera.
这个函数带有在屏幕坐标的x-y组件向量,并且z组件是在从相机产生的平面的距离。
