This is a gathering topic for recommendations/requests/contributions of OpenTK Tutorials that should be added. Please keep this sane (noone will port Quake III's source code for a tutorial) and be verbose what the tutorial should achieve, i.e. with that knowledge the reader should end up with after reading the source code.
There's no limit how small or big the tutorial should be, but some things need to be part of a larger tutorial (e.g. load a texture and draw a textured quad - makes little sense separated)
Also note that the tutorials on this list will not necessarily be finished tomorrow, it's more a list of feedback from users to get an idea what is missing and which areas require improvements. Posts like "I second [name]'s suggestion" are very welcome too, as this helps to set priorities! Thank you :)
Free your mind ...
Edit: this topic isn't much for discussion of the suggestion's details, so don't be confused if you get no reply. All suggestions will be read and considered.
Don't be afraid to add wishes that might sound trivial or stupid, the tutorials are supposed to help beginners get a good start with OpenTK and without you voicing the problems there cannot be done anything about this.
