Transforms position from viewport space into screen 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.
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.
using UnityEngine;
public class Example : MonoBehaviour { // Draw an image based on normalized view coordinates // rather than pixel positions. Texture2D bottomPanel;
void VPToScreenPtExample() { var origin = Camera.main.ViewportToScreenPoint(new Vector3(0.25f, 0.1f, 0)); var extent = Camera.main.ViewportToScreenPoint(new Vector3(0.5f, 0.2f, 0));
GUI.DrawTexture(new Rect(origin.x, origin.y, extent.x, extent.y), bottomPanel); } }
