osuTK

MAINTAINERS WANTED

osuTK is a large project, with a huge number of components. We're looking to add a more maintainers to the team. Email @varon or message him in Gitter if you'd like to help out.

The Open Toolkit library is a fast, low-level C# binding for OpenGL, OpenGL ES and OpenAL. It runs on all major platforms and powers hundreds of apps, games and scientific research.

Use osuTK to add cross-platform 3d graphics, audio, compute and haptics to your C# application. Integrate it into your existing user interface or use it standalone without any external dependencies.

Build Status

Platform	Status
Windows
Mono/Linux

Features

• Create cutting-edge graphics with OpenGL 4.6 and OpenGL ES 3.0
• Spice up your GUI with 3d acceleration
• Improve your code flow with strong types and inline documentation
• Write once run everywhere

osuTK is available for Windows, Linux, Mac OS X, *BSD, SteamOS, Android and iOS. It can be used standalone or integrated into a GUI (Windows.Forms, WPF, GTK+, Qt, VTK, ...)

Download binaries or NuGet packages

Instructions

The simplest way to use osuTK in your project is to install the NuGet package. If you want to try out the latest development build from the develop branch, we also have a MyGet feed.

Note what installing NuGet package will add reference to osuTK.dll, but osuTK.dll.config will not be copied to the project output directory automatically, so you need to add it to your project and then enable the "Copy to Output Directory" option (as in step 3 below).

To build osuTK from source, do the following once:

git clone https://github.com/opentk/opentk   # Download source code from git
cd opentk                                    # Enter the source directory
./build.cmd                                  # Build on .Net (Windows)
./build.sh                                   # Build on Mono (Linux / Mac OS X)

After this is done at least once, you can build osuTK normally through your IDE.

osuTK 2.0.0 is now available for download from Nuget.

Aside from being a maintenance release to bring the current package closer in-line with develop, this the project's first release since adopting a new build system.

Release notes:

• Moved to new FAKE/Paket based build system
• Removed superfluous release configurations
• Numerous other fixes and enhancements

We would welcome any feedback on the package, so please open a GitHub issue if you require assistance or experience difficulties.

2014-07-24

osuTK 1.1.4c was released on 24 July 2014.

This is a hotfix release that improves stability on Mac OS X. Moreover, it synchronizes the GamePad configuration database with SDL 2.0.4 and fixes an invalid GUID introduced in 1.1.4b.

2014-07-21

osuTK 1.1.4 was released on 21 July 2014.

This release resolves a number of identified issues, adds experimental support for Linux/KMS and synchronizes the OpenGL and OpenGL ES bindings with the July 2014 Khronos specifications.

Changelog:

1. Fixed a memory leak in OpenGL functions accepting a string array.
2. Fixed an issue where MakeCurrent() might fail on Linux/X11 when using the Nvidia closed-source drivers.
3. Fixed an issue where GameWindow might remain open on Linux/X11 after calling Close() or Dispose().
4. Fixed a potential crash on Mac OS X systems without hardware acceleration (e.g. virtual machines).
5. Fixed function parameters for the OES_byte_coordinates extension.
6. Fixed an issue where osuTK would always perform a full rebuild even when a partial rebuild could work.
7. Fixed all compilation warnings on VS2013 and Mono 3.4.0.
8. Improved OpenGL and OpenGL ES documentation on 'count' parameters.
9. New platform: Linux/KMS. You can now run osuTK applications on a Linux terminal without an X11 display server.
10. New OpenGL ES extensions:

• ANDROID_extension_pack_es31a

osuTK 1.1.4 is backwards compatible with 1.1.3. Users of previous versions are strongly encouraged to upgrade.

Known issues

1. The SDL2 backend has a number of limitations compared to the native platform backends. In particular, SDL2 does not support:
   • osuTK.GLControl. osuTK will automatically switch to a native platform backend instead.
   • DisplayDevice.ChangeResolution() without a fullscreen INativeWindow.
   • Switching between WindowBorder.Fixed and WindowBorder.Resizable.
   • High-resolution mouse input. Additionally, it is limited to a single keyboard and mouse device.
2. osuTK.Input.GamePad.SetVibration is currently not implemented. This API will be implemented in a future release.

Contributing

1. Install git and a C# IDE (see requirements section below)
2. Fork the develop branch of https://github.com/opentk/opentk
3. Commit your changes in small, incremental steps with clear descriptions
4. When ready, issue a Pull Request (PR) against the develop branch of https://github.com/opentk/opentk
