The new function reference for OpenTK is now available online. It includes documentation and class diagrams for all public OpenTK 1.0 members, as well as the various native APIs (OpenGL, OpenGL ES, OpenAL). The reference will also be available offline in PDF format.

Many thanks to the doxygen team for creating such a useful tool!

Containing a significant amount of bug- and stability fixes, OpenTK 1.0 beta-1 is released to the world. Download from Sourceforge.

Feature highlights:

• A large number of new examples.
• Various stability fixes on all operating systems.
• Improved support for multithreading.
• Type-safe OpenGL|ES 2.0 bindings.

Due to the number and significance of the included bug fixes, users are strongly encouraged to upgrade from earlier versions.

Warning: a number of features did not make the cut for 1.0 beta-1 and will not appear in the final 1.0 release. These features include the OpenTK.Compute.CL10 and OpenTK.Graphics.ES10/ES11 namespaces. If your code requires support for these features, please recompile OpenTK with the EXPERIMENTAL compiler flag or download the latest 1.x-dev release.

A must read for all OpenGL developers: OpenGL 3.2 quick reference card! Also available for OpenCL.

Kudos to Khronos for creating those PDFs. They are invaluable for looking up some specific parameter or function quickly.

Now, I'm going to print them out and keep them by my workstation.

OpenTK 0.9.8-3 is the final bugfix release in the 0.9.8 series. Read the complete 0.9.8-3 release notes.

OpenTK 0.9.9-2 is the third work-in-progress snapshot of the 0.9.9 series that will lead to our first stable release. 0.9.9-2 contains significant changes to the project structure. Please read the [API changes] section on the 0.9.9-2 release notes.

Important: the 0.9.9-2 release has been superseded by 0.9.9-2b, due to an issue with missing AllowPartialTrustedCallers attributes. If you have downloaded 0.9.9-2, please re-download 0.9.9-2b. Thank you for your understanding.

Update: current efforts are focused on Cloo (object-oriented CL wrapper), which can be found here. It provides a much cleaner OpenCL API compared to raw bindings (which are also available in case you need them).

The generator now supports generating C# OpenCL wrappers from the C headers. The OpenCL wrappers reside under the OpenTK.Compute.CL10 namespace of SVN trunk. An OpenCL sample has also been added to Examples.exe: if you have access to an OpenCL implementation, please run the VectorAdd sample and report your results here.

AMD has released a public beta of its OpenCL implementation that you can download from AMD's developer website (free registration needed). This implementation runs on all SSE3-capable CPUs and is available for Window and Linux platforms.

There is a lot of fine-tuning left to do for OpenTK's OpenCL wrappers and the sooner you test the bindings, the sooner they will become ready for release.

OpenTK 0.9.8-2 is a bugfix release in the 0.9.8 series. Features:

• TextPrinter.Print() no longer ignores the specified color.
• Various GL methods with string[] parameters are now correctly wrapped.

Read the complete 0.9.8-2 release notes.

OpenTK 0.9.9-1 is a work-in-progress snapshot of what will become our first stable release. This release is strictly for testing and feedback purposes: if you are a new user, you are strongly advised to stay with the 0.9.8 series until the new code stabilizes.

Features:

• Initial OpenGL 3.2 support.
• Initial support for OpenGL ES 1.0, 1.1 and 2.0.
• Bugfixes for OpenCL, OpenAL and OpenGL.
• Various changes and bugfixes to the math library and the GameWindow.

Major changes are in progress, so please expect bugs and missing features. In particular, Mac OS X support may be broken and the new GameWindow and OpenTK.Input APIs are incomplete.
