메소드	설명
GetDelegateForExtensionMethod ( string name, Type signature ) : Delegate	Creates a System.Delegate that can be used to call a dynamically exported OpenGL function.
GetDelegateForMethod ( string methodName, Type signature ) : Delegate	Creates a callable delegate for the specified OpenGL function (core or extension), if it exists.
GetFunctionPointerForExtensionMethod ( string name ) : IntPtr	Retrieves the entry point for a dynamically exported OpenGL function. 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. Marshal.GetDelegateForFunctionPointer Gl.GetDelegateForExtensionMethod
IsExtensionSupported ( string name ) : bool	Determines whether the specified OpenGL extension category is available in the current OpenGL context. Equivalent to IsExtensionSupported(name, true)
IsExtensionSupported ( string name, bool useCache ) : bool	Determines whether the specified OpenGL extension category is available in the current OpenGL context.
ReloadFunction ( string name ) : bool	Tries to reload the given OpenGL function (core or extension). 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 will return true if the given OpenGL function exists, false otherwise. A return value of "true" does not mean that any specific OpenGL function is supported; rather it means that the string passed to this function denotes a known OpenGL function. To query supported extensions use the IsExtensionSupported() function instead.
ReloadFunctions ( ) : void	Reloads all OpenGL functions (core and extensions). Call this function to reload all OpenGL entry points. This should be done whenever you change the pixelformat/visual, or in the case you cannot (or do not want) to use the automatic initialisation. Calling this function before the automatic initialisation has taken place will result in the Gl class being initialised twice. This is harmless, but, given the choice, the automatic initialisation should be preferred.

메소드 상세

GetDelegateForExtensionMethod() 공개 정적인 메소드

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

public static GetDelegateForExtensionMethod ( string name, Type signature ) : Delegate
name	string	The function string for the OpenGL function (eg. "glNewList")
signature	Type	The signature of the OpenGL function.
리턴	Delegate

GetDelegateForMethod() 공개 정적인 메소드

Creates a callable delegate for the specified OpenGL function (core or extension), if it exists.

public static GetDelegateForMethod ( string methodName, Type signature ) : Delegate
methodName	string	The OpenGL function name (e.g. glVertex3f)
signature	Type	The signature of the delegate to return.
리턴	Delegate

GetFunctionPointerForExtensionMethod() 공개 정적인 메소드

Retrieves the entry point for a dynamically exported OpenGL function.

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.

Marshal.GetDelegateForFunctionPointer Gl.GetDelegateForExtensionMethod

public static GetFunctionPointerForExtensionMethod ( string name ) : IntPtr
name	string	The function string for the OpenGL function (eg. "glNewList")
리턴	IntPtr

IsExtensionSupported() 공개 정적인 메소드

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

public static IsExtensionSupported ( string name ) : bool
name	string	The string for the OpenGL extension category (eg. "GL_ARB_multitexture")
리턴	bool

IsExtensionSupported() 공개 정적인 메소드

Determines whether the specified OpenGL extension category is available in the current OpenGL context.

public static IsExtensionSupported ( string name, bool useCache ) : bool
name	string	The string for the OpenGL extension category (eg. "GL_ARB_multitexture")
useCache	bool	If true, the results will be cached to speed up future results.
리턴	bool

ReloadFunction() 공개 정적인 메소드

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

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 will return true if the given OpenGL function exists, false otherwise. A return value of "true" does not mean that any specific OpenGL function is supported; rather it means that the string passed to this function denotes a known OpenGL function.

To query supported extensions use the IsExtensionSupported() function instead.

public static ReloadFunction ( string name ) : bool
name	string	The name of the OpenGL function (i.e. glShaderSource)
리턴	bool

ReloadFunctions() 공개 정적인 메소드

Reloads all OpenGL functions (core and extensions).

Call this function to reload all OpenGL entry points. This should be done whenever you change the pixelformat/visual, or in the case you cannot (or do not want) to use the automatic initialisation.

Calling this function before the automatic initialisation has taken place will result in the Gl class being initialised twice. This is harmless, but, given the choice, the automatic initialisation should be preferred.
