function ScreenToWorldPoint (position : Vector3) : Vector3


Transforms position from screen space into world space.

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

// Draw a yellow sphere in the scene view at the position
// on the near plane of the selected camera that is
// 100 pixels from lower-left.
function OnDrawGizmosSelected () {
var p = camera.ScreenToWorldPoint (Vector3 (100,100,camera.nearClipPlane));
Gizmos.color = Color.yellow;
Gizmos.DrawSphere (p, 0.1);
