Is there any way to activate multisampling with MonoTouch and OpenGL ES 2.0? I can't find the apple extension in the framework, so i think it's not implemented?

Functions like glRenderbufferStorageMultisampleAPPLE and glResolveMultisampleFramebufferAPPLE are not presently included in MonoTouch's OpenGL bindings. I'm not sure if they are included in the latest OpenTK bits.

Anyway whenever you find missing pieces you should fill a bug report (enhancement) on http://bugzilla.xamarin.com That will ensure you get notified on the progress of the bug/enhancement request.

UPDATE: MonoTouch 5.2.3 (stable) has been released and includes OpenTK 1.0 (which defines the mentioned symbols).

  • I'm wondering about this, because the multisampling is supported since iOS 4.0. Maybe i can invoke the method call with C#. – Felix K. Nov 17 '11 at 15:51
  • Yes, you can likely add the p/invoke inside your own application and use them. Most of the MonoTouch code wrt OpenGL is opensource (OpenTK) so interop should not be overly complicated. – poupou Nov 17 '11 at 16:05
  • Please note that MonoTouch uses a forked version of OpenTK that is closed-source. While most of the code is similar, there are a few significant differences: (a) upstream OpenTK includes all official OpenGL ES extensions, whereas MonoTouch doesn't; (b) upstream OpenTK uses strongly-typed enums, whereas MonoTouch uses the 'All' enum. There is little upstream OpenTK can do to improve the situation (the closed-source nature of the fork and the cost of MonoTouch are prohibitive). – The Fiddler Jan 24 '12 at 21:50
