Mogre and WPF         Information and links for WPF interaction


WPF (Windows Presentation Foundation) is a modern SDK created by Microsoft for building GUIs in Windows. Many powerful Windows applications today, including Visual Studio 2010 and later, are built using WPF. WPF makes it easy to create sophisticated GUI controls that are composed of other controls. It also has support for animation, styling, and data binding. It optionally supports a declarative UI layout through a XML format called XAML.

UI toolkits for games are often simpler and less featureful than desktop-grade UI toolkits. Incorporating WPF into a Mogre application allows a developer to have a sophisticated UI and leverage the vast wealth of WPF resources available.

Methods of Combining WPF and Mogre

There are several ways of using WPF and Mogre together. Note that most are in an experimental state.
Here are the possibilities:

Mogre In WPF

D3DImage is a WPF control that shows a Direct3D texture inside WPF. It can be set to use a texture that Mogre renders to.


  • The result is a fully interactive WPF application with all WPF features supported.
  • The Mogre scene can be partially transparent, with WPF elements behind it. Partially transparent WPF elements can be placed on top of the Mogre scene.


  • WPF controls the rendering loop
  • WPF's rendering loop is locked at Vsync (e.g. 60FPS)

Approaches to implementation:

  • Single vs Double buffering
  • Timing of Ogre rendering
    • CompositionTarget.Rendering event
    • DispatcherInactive event
    • DispatcherTimer
    • Timer
    • Loop in separate thread

WPF on Mogre (Overlay technique)

This approach takes two Windows windows: the top is mostly transparent and contains some WPF controls, while the bottom is a typical Mogre window. The positions of the two windows are synced, and input from the user can go to either window.


  • Mogre Rendering rate is not constrained to WPF rendering, as it is in the 'Mogre In WPF' approach.


  • It can be tricky to cleanly keep two windows in sync, with input working nicely between the two.

WPF in Mogre

Capture a screenshot of individual WPF visuals and render them as textures onto entities in Ogre or Mogre.


  • You can position GUI elements in 3D space as Ogre Scene Nodes
  • You have full control over when WPF is rendered to an Ogre scene, which might facilitate high performance scenarios.


  • It is up to you to arrange WPF controls on the screen. (Perhaps this is simpler if you capture an entire WPF window.)
  • It is up to you to handle input to make the WPF elements interactive. (Not an issue if you only use WPF as a HUD that requires no input.)
  • No open source implementation is known that provides interactivity.
