The OpenGL ARB ... [More] (Architecture Review Board) working group at Khronos has defined GLSL 1.5, an updated version of the OpenGL Shading language, and two profiles within the OpenGL 3.2 specification providing developers the choice of using the streamlined Core profile for new application development or the Compatibility profile which provides full backwards compatibility with previous versions of the OpenGL standard for existing and workstation applications. OpenGL 3.2 has been designed to run on a wide range of recent GPU silicon and provides a wide range of significant benefits to application developers, including: Increased performance for vertex arrays and fence sync objects to avoid idling while waiting for resources shared between the CPU and GPU, or multiple CPU threads; Improved pipeline programmability, including geometry shaders in the OpenGL core; Boosted cube map visual quality and multisampling rendering flexibility by enabling shaders to directly process texture samples. In addition, Khronos has defined a set of five new ARB extensions that enable the very latest graphics functionality introduced in the newest GPUs to be accessed through OpenGL – these extensions will be absorbed into the core of a future version of OpenGL when this functionality is proven and widely adopted. Read the full announcement on opengl.org. The specification is already available for download - expect a new OpenTK release soon. read more [Less]

OpenGL ES is a subset of the OpenGL API used in embedded devices. It is used by Apple's iPhone, Google's Android, Nokia's Maemo, the Sony Playstation 3, the Pandora handheld and other devices. OpenTK now offers experimental support for OpenGL ES ... [More] profiles 1.0, 1.1 and 2.0, which roughly translate to OpenGL 1.3, 1.5 and 2.0 respectively. This includes inline documentation but excludes strongly-typed enums, which will be added at a later time. There is also no support for constructing contexts through EGL, however it should be possible to use an external GL ES context in conjuction with OpenTK. Finally, the bindings are untested - please file any bugs you encounter. If you are interested in helping out, testing or porting (esp. to iPhone and Android), make a post! [Less]

Download OpenTK 0.9.8-1 Download OpenTK 0.9.9-0 OpenTK 0.9.8-1 is a bugfix release in the 0.9.8 series. Features: TextPrinter.Clear() no longer corrupts text rendering. Matrix4.CreateOrthographic() no longer returns an invalid matrix. ... [More] Optimized Matrix4.Mult() should increase matrix multiplication speed by 50-100%. OpenTK.Math now contains Vector[234].One readonly properties. Read the complete 0.9.8-1 release notes. OpenTK 0.9.9 is the first step in what will lead to our first stable release. This release is strictly for testing and feedback purposes: if you are a new user, you are strongly advised to remain with OpenTK 0.9.8-1, above. Features: Support for the OpenCL flat API in OpenTK.Compute.CL. Extensive changes to the GameWindow. You can now control most visible aspects, including the position on the screen. Improved support for Windows Vista and Windows 7. Support for multisampling on Windows systems. Several obsolete APIs have been removed or marked as deprecated. 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.
