Camera.ViewportToWorldPoint 视窗转世界位置

function ViewportToWorldPoint (position : Vector3) : Vector3


Transforms position from viewport space into world space.


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.


Note that it transforms a x-y screen position, into a x-y-z position in 3D space.


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.

public class example : MonoBehaviour {
	void OnDrawGizmosSelected() {
		Vector3 p = camera.ViewportToWorldPoint(new Vector3(1, 1, camera.nearClipPlane));
		Gizmos.color = Color.yellow;
		Gizmos.DrawSphere(p, 0.1F);
// Draw a yellow sphere at top-right corner of the near plane
// for the selected camera in the scene view.
function OnDrawGizmosSelected () {
	var p : Vector3 = camera.ViewportToWorldPoint (Vector3 (1,1, camera.nearClipPlane));
	Gizmos.color = Color.yellow;
	Gizmos.DrawSphere (p, 0.1);
