The graphics service (interface IGraphicsService) is the main interface for graphics-related tasks. It provides access to the graphics device (see GraphicsDevice), the main game window (see GameForm, Windows only), the graphics screens (see Graphics Screens) and a RenderTargetPool.

Graphics screens render game content, like the 3D scene or the HUD. The graphics service manages a collection of screens, which are rendered back to front. The graphics are displayed in a presentation target (see Windows Forms, WPF, UWP Interoperability), which is either a window, a Windows Forms control or a WPF control.

The graphics service is implemented by the class GraphicsManager. The following examples shows how to add the graphics service to an XNA game.

using DigitalRune.Graphics;
using Microsoft.Xna.Framework;

namespace GeneralSamples
{
  public class MyGame : Game
  {
    private GraphicsManager _graphicsManager;

    public MyGame()
    {
      var graphicsDeviceManager = new GraphicsDeviceManager(this)
      {
        PreferredBackBufferWidth = 1280,
        PreferredBackBufferHeight = 720,
        PreferMultiSampling = false,
      };
      Content.RootDirectory = "Content";
    }

    protected override void Initialize()
    {
      _graphicsManager = new GraphicsManager(GraphicsDevice, Window, Content);

      ...

      base.Initialize();
    }

    protected override void Update(GameTime gameTime)
    {
      ...

      base.Update(gameTime);
    }

    protected override void Draw(GameTime gameTime)
    {
      _graphicsManager.Update(gameTime.ElapsedGameTime);
      _graphicsManager.Render(false);

      base.Draw(gameTime);
    }
  }
}
