# RenderMeshProvider class

Namespace: [Rhino.Render.CustomRenderMeshes](https://developer.rhino3d.com/api/rhinocommon/namespace/rhino.render.customrendermeshes.md) · Assembly: [RhinoCommon](https://developer.rhino3d.com/api/rhinocommon/assembly/rhinocommon.md)

```cs
public abstract class RenderMeshProvider : IDisposable
```

A RenderMeshProvider delivers custom render primitives (in the form of RenderMeshes). Derive a public class from this with a public constructor, and this primitive provider will be added to the RDK forming a collection of providers. Each RenderMeshProvider::HasCustomRenderMeshes will be called and if it returns true, a call to RenderMeshes will be made. It is up to the provider to cache its own primitives - the IRenderMeshes::ProviderTracking class is provided for that. A provider may optionally return a collection of non-object Ids that it will provide custom render primitives for. An example of this is Grasshopper, which which will typically return a collection of the Ids of each CustomPreview component. Override this class if you are a plug-in developer intending to supply a custom set of primitives for a given object, or objectId. Examples of IRenderMeshProviders are CurvePiping, EdgeSoftening, Displacement, Shutlining, Grasshopper's CustomPreview component.
