position | 视口空间中的 3D 矢量。 |
Vector3 世界空间中的 3D 矢量。
将 position
从视口空间变换为世界空间。
视口空间是标准化的、相对于摄像机的空间。视口左下角为 (0,0),
右上角为 (1,1)。z 位置为与摄像机的距离,采用世界单位。
注意,ViewportToWorldPoint 将 x-y 屏幕位置变换为 3D 空间中的 x-y-z 位置。
请为该函数提供一个矢量,其中矢量的 x-y 分量为屏幕坐标,
z 分量为最终平面到摄像机的距离。
// Draw a yellow sphere at top-right corner of the near plane // for the selected camera in the Scene view. using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { void OnDrawGizmosSelected() { Camera camera = GetComponent<Camera>(); Vector3 p = camera.ViewportToWorldPoint(new Vector3(1, 1, camera.nearClipPlane)); Gizmos.color = Color.yellow; Gizmos.DrawSphere(p, 0.1F); } }
