# NormalAndDistance

> A plane in the form Ax + By + Cz + Dw = 0.

## Definition

* **Type:** Field
* **Namespace:** [Unity.Mathematics.Geometry](/engine/6000.5/script-reference/unity/mathematics/geometry.md)
* **Assembly:** UnityEngine.MathematicsModule

```csharp
public float4 NormalAndDistance
```

### Remarks

Stores the plane coefficients A, B, C, D where (A, B, C) is a unit normal vector and D is the distance from the origin.  A plane stored with a unit normal vector is called a normalized plane.
