* **Assembly:** UnityEngine.CoreModule

## WorldToScreenPoint(Vector3, MonoOrStereoscopicEye)

Transforms `position` from world space into screen space.

```csharp
public Vector3 WorldToScreenPoint(Vector3 position, Camera.MonoOrStereoscopicEye eye)
```

### Parameters

**** (\[Vector3]\(/engine/6000.5/script-reference/unityengine/vector3)): A 3D point in world space.**** (\[MonoOrStereoscopicEye]\(/engine/6000.5/script-reference/unityengine/camera/monoorstereoscopiceye)): Optional argument that can be used to specify which eye transform to use. Default is Mono.

### Returns

| Type                                                              | Description |
| ----------------------------------------------------------------- | ----------- |
| [Vector3](/engine/6000.5/script-reference/unityengine/vector3.md) |             |

### Remarks

Screen space is defined in pixels. The lower left pixel of the screen is (0,0). The upper right pixel of the screen is (screen width in pixels - 1, screen height in pixels - 1).

The z coordinate is the distance from the camera in world units.

If `position` is outside the Camera's viewing volume, Unity returns a screen position that's off-screen.

### Examples

```csharp
using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour
{
    public Transform target;
    Camera cam;

    void Start()
    {
        cam = GetComponent<Camera>();
    }

    void Update()
    {
        Vector3 screenPos = cam.WorldToScreenPoint(target.position);
        Debug.Log("target is " + screenPos.x + " pixels from the left");
    }
}
```

## WorldToScreenPoint(Vector3)

Transforms `position` from world space into screen space.

```csharp
public Vector3 WorldToScreenPoint(Vector3 position)
```

### Parameters

**** (\[Vector3]\(/engine/6000.5/script-reference/unityengine/vector3)): A 3D point in world space.

### Returns

| Type                                                              | Description |
