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.
// 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);
}
