Custom scene renderers

To create a custom renderer, directly implement the @'Stride.Rendering.Compositing.ISceneRenderer' or use a delegate through the @'Stride.Rendering.Compositing.DelegateSceneRenderer'.

Implement an ISceneRenderer

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

[DataContract("MyCustomRenderer")]
[Display("My Custom Renderer")]
public sealed class MyCustomRenderer : SceneRendererBase
{
    // Implements the DrawCore method
    protected override void DrawCore(RenderContext context, RenderDrawContext drawContext)
    {
        // Access to the graphics device
        var graphicsDevice = drawContext.GraphicsDevice;
        var commandList = drawContext.CommandList;
        // Clears the current render target
        commandList.Clear(commandList.RenderTargets[0], Color.CornflowerBlue);
        // [...] 
    }
}

Use a delegate

To develop a renderer and attach it to a method directly, use @'Stride.Rendering.Compositing.DelegateSceneRenderer':

var sceneRenderer = new DelegateSceneRenderer(
    (drawContext) =>
    {
        // Access to the graphics device
        var graphicsDevice = drawContext.GraphicsDevice;
        var commandList = drawContext.CommandList;
        // Clears the current render target
        commandList.Clear(commandList.RenderTargets[0], Color.CornflowerBlue);
        // [...] 
   });
