Custom scene renderers

To create a custom renderer, directly implement the ISceneRenderer or use a delegate through the DelegateSceneRenderer.

Implement an ISceneRenderer

The SceneRendererBase provides a default implementation of ISceneRenderer. It automatically binds the output defines on the renderer to the GraphicsDevice before calling the DrawCore method.

  1. [DataContract("MyCustomRenderer")]
  2. [Display("My Custom Renderer")]
  3. public sealed class MyCustomRenderer : SceneRendererBase
  4. {
  5.     // Implements the DrawCore method
  6.     protected override void DrawCore(RenderContext context, RenderFrame output)
  7.     {
  8.         // Access to the graphics device
  9.         var graphicsDevice = context.GraphicsDevice;
  10.         // Clears the currrent render target
  11.         graphicsDevice.Clear(output.RenderTargets[0], Color.CornflowerBlue);
  12.         // [...] 
  13.     }
  14. }

Use a delegate

To develop a renderer and attach it to a method directly, use DelegateSceneRenderer:

  1. var sceneRenderer = new DelegateSceneRenderer(
  2.     (renderContext, frame) =>
  3.     {
  4.         // Access to the graphics device
  5.         var graphicsDevice = context.GraphicsDevice;
  6.         // Clears the currrent render target
  7.         graphicsDevice.Clear(output.RenderTargets[0], Color.CornflowerBlue);
  8.         // [...] 
  9.    });
