## MultiplyPoint(Vector3)

Transforms a position by this matrix (generic).

```csharp
public readonly Vector3 MultiplyPoint(Vector3 point)
```

### Parameters

**** (\[Vector3]\(/engine/6000.5/script-reference/unityengine/vector3)): 

### Returns

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

### Remarks

Returns a position `v` transformed by the current fully arbitrary matrix. If the matrix is a regular 3D transformation matrix, it is much faster to use [Matrix4x4.MultiplyPoint3x4](/engine/6000.5/script-reference/unityengine/matrix4x4/multiplypoint3x4.md) instead. `MultiplyPoint` is slower, but can handle projective transformations as well.

### Examples

```csharp
using UnityEngine;

public class ScriptExample : MonoBehaviour
{
  void Start()
  {
    // Find our current location in the camera's projection space.
    Vector3 pt = Camera.main.projectionMatrix.MultiplyPoint(transform.position);
  }
}
```

```csharp

```

### Parameters

### Returns

| Type                                                              | Description |
