This function makes a specified context the current context.

A pointer to the new context. Returns True on success, or False on failure.

This function tells a context to begin processing. When a context is suspended, changes in OpenAL state will be accepted but will not be processed. alcSuspendContext can be used to suspend a context, and then all the OpenAL state changes can be applied at once, followed by a call to alcProcessContext to apply all the state changes immediately. In some cases, this procedure may be more efficient than application of properties in a non-suspended state. In some implementations, process and suspend calls are each a NOP.

a pointer to the new context

This function suspends processing on a specified context. When a context is suspended, changes in OpenAL state will be accepted but will not be processed. A typical use of alcSuspendContext would be to suspend a context, apply all the OpenAL state changes at once, and then call alcProcessContext to apply all the state changes at once. In some cases, this procedure may be more efficient than application of properties in a non-suspended state. In some implementations, process and suspend calls are each a NOP.

OpenGL binding for .NET, implementing OpenGL 2.1, plus extensions.

This class contains all OpenGL enums and functions defined in the 2.1 specification. The official .spec files can be found at: http://opengl.org/registry/. We rely on static initialization to obtain the entry points for OpenGL functions. Please ensure that a valid OpenGL context has been made current in the pertinent thread before any OpenGL functions are called (toolkits like GLUT, SDL or GLFW will automatically take care of the context initialization process). Without a valid OpenGL context, we will only be able to retrieve statically exported entry points (typically corresponding to OpenGL version 1.1 under Windows, 1.3 under Linux and 1.4 under Windows Vista), and extension methods will need to be loaded manually. If you prefer to have more control on extension loading, you can use the ReloadFunctions or ReloadFunction methods to manually force the initialisation of OpenGL entry points. The ReloadFunctions method should be called whenever you change an existing visual or pixelformat. This generally happens when you change the color/stencil/depth buffer associated with a window (but probably not the resolution). This may or may not be necessary under Linux/MacOS, but is generally required for Windows. You can use the Gl.IsExtensionSupported method to check whether any given category of extension functions exists in the current OpenGL context. The results can be cached to speed up future searches. Keep in mind that different OpenGL contexts may support different extensions, and under different entry points. Always check if all required extensions are still supported when changing visuals or pixel formats. You may retrieve the entry point for an OpenGL function using the Gl.GetDelegate method.

Determines whether the specified OpenGL extension category is available in the current OpenGL context. Equivalent to IsExtensionSupported(name, true)

The string for the OpenGL extension category (eg. "GL_ARB_multitexture") True if the specified extension is available, false otherwise.

Creates a System.Delegate that can be used to call an OpenGL function, core or extension.

Loads all OpenGL functions (core and extensions).

This function will be automatically called the first time you use any opengl function. There is Call this function manually whenever you need to update OpenGL entry points. This need may arise if you change the pixelformat/visual, or in case you cannot (or do not want) to use the automatic initialization of the GL class.

Tries to reload the given OpenGL function (core or extension).

The name of the OpenGL function (i.e. glShaderSource) True if the function was found and reloaded, false otherwise. Use this function if you require greater granularity when loading OpenGL entry points. While the automatic initialisation will load all OpenGL entry points, in some cases the initialisation can take place before an OpenGL Context has been established. In this case, use this function to load the entry points for the OpenGL functions you will need, or use ReloadFunctions() to load all available entry points. This function returns true if the given OpenGL function is supported, false otherwise. To query for supported extensions use the IsExtensionSupported() function instead.

Builds a cache of all supported extensions.

Retrieves the entry point for a dynamically exported OpenGL function.

The function string for the OpenGL function (eg. "glNewList") An IntPtr contaning the address for the entry point, or IntPtr.Zero if the specified OpenGL function is not dynamically exported. The Marshal.GetDelegateForFunctionPointer method can be used to turn the return value into a call-able delegate. This function is cross-platform. It determines the underlying platform and uses the correct wgl, glx or agl GetAddress function to retrieve the function pointer.

Executes "uname" which returns a string representing the name of the underlying Unix kernel.

"Unix", "Linux", "Darwin" or null. Source code from "Mono: A Developer's Notebook"

Creates a System.Delegate that can be used to call a dynamically exported OpenGL function.

The name of the OpenGL function (eg. "glNewList") The signature of the OpenGL function. A System.Delegate that can be used to call this OpenGL function or null if the function is not available in the current OpenGL context.

Contains DllImports for the core OpenGL functions.

Build a string->MethodInfo map to speed up extension loading.

OpenGL bindings for .NET, implementing OpenGL 3.1, plus extensions.

This class contains all OpenGL enums and functions defined in the 3.1 specification. The official .spec files can be found at: http://opengl.org/registry/. A valid OpenGL context must be created before calling any OpenGL function. Use the GL.Load and GL.LoadAll methods to prepare function entry points prior to use. To maintain cross-platform compatibility, this must be done for both core and extension functions. The GameWindow and the GLControl class will take care of this automatically. You can use the GL.SupportsExtension method to check whether any given category of extension functions exists in the current OpenGL context. Keep in mind that different OpenGL contexts may support different extensions, and under different entry points. Always check if all required extensions are still supported when changing visuals or pixel formats. You may retrieve the entry point for an OpenGL function using the GL.GetDelegate method.
