Constructors

this this(Logger logger): Load OpenGL library, redirect debug output to our logger. You can pass a null logger if you don't want logging.

Destructor

~this ~this(): Undocumented in source.

Members

Enums

Vendor enum Vendor: Undocumented in source.

Functions

close void close(): Releases the OpenGL dynamic library. All resources should have been released at this point, since you won't be able to call any OpenGL function afterwards.
debugCheck void debugCheck(): Check for pending OpenGL errors, log a message if there is. Only for debug purpose since this check will be disabled in a release build.
getExtensions string[] getExtensions()
getExtensionsString deprecated string getExtensionsString()
getFloat float getFloat(GLenum pname)
getFloat float getFloat(GLenum pname, GLfloat defaultValue, bool logging)
getGLSLVersionString string getGLSLVersionString()
getInteger bool getInteger(GLenum pname, int result): Calls glGetIntegerv and gives back the requested integer.
getInteger int getInteger(GLenum pname, GLint defaultValue, bool logging)
getMajorVersion int getMajorVersion()
getMinorVersion int getMinorVersion()
getRendererString string getRendererString()
getString string getString(GLenum name)
getString string getString(GLenum name, GLuint index)
getVendor Vendor getVendor(): Tries to detect the driver maker.
getVendorString string getVendorString()
getVersionString string getVersionString()
maxColorAttachments int maxColorAttachments()
maxCombinedImageUnits int maxCombinedImageUnits()
maxFragmentTextureImageUnits int maxFragmentTextureImageUnits()
maxTextureMaxAnisotropy float maxTextureMaxAnisotropy()
maxTextureSize int maxTextureSize()
maxTextureUnits int maxTextureUnits()
maxVertexImageUnits int maxVertexImageUnits()
reload void reload(): Reload OpenGL function pointers. Once a first OpenGL context has been created, you should call reload() to get the context you want.
runtimeCheck void runtimeCheck(): Checks pending OpenGL errors.
runtimeCheckNothrow bool runtimeCheckNothrow(): Checks pending OpenGL errors.
supportsExtension bool supportsExtension(string extension)
textureUnits TextureUnits textureUnits()

Static functions
