## Geometry class

The base class of all renderable geometric objects (like [`Mesh`](../mesh/), [`NurbsSurface`](../nurbssurface/), [`Patch`](../patch/) and etc.).

The `Geometry` base class supports: **Control point management**, control points defines the base 3D spatial structure of the geometry, different geometric types has different way to define concrete 3D models. **Vertex element definition**, vertex elements applies extra information like normals/uv coordinates/vertex colors to the geometry, see [`VertexElement`](../vertexelement/) for more details.**Object deforming**, [`Deformer`](../../aspose.threed.deformers/deformer/) can be bonded to animate geometry's shape.

```csharp
public class Geometry : Entity
```
