# Curvature

> Bi-axial curvature applied to a visual element's generated mesh. The element bends around its X axis by _x (curving the vertical extent) and around its Y axis by _y (curving the horizontal extent); the sign of each angle selects concave vs. convex.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine.UIElements](/engine/6000.7/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule
* **Implements:** [IEquatable\<Curvature>](https://learn.microsoft.com/dotnet/api/system.iequatable-1)

```csharp
public struct Curvature : IEquatable<Curvature>
```

## Remarks

Curvature describes surface shape only — placement and orientation still come from the element's transform. It is only visually meaningful on world-space panels.
