Static Public Member Functions | |
| static GLenum | GetGLType (GLubyte const *) |
| Returns the OpenGL type identifier that corresponds to unsigned byte. | |
| static GLenum | GetGLType (GLushort const *) |
| Returns the OpenGL type identifier that corresponds to unsigned short. | |
| static GLenum | GetGLType (GLfloat const *) |
| Returns the OpenGL type identifier that corresponds to float. | |
| static GLenum | GetGLType (GLbyte const *) |
| Returns the OpenGL type identifier that corresponds to byte. | |
| static GLenum | GetGLType (GLshort const *) |
| Returns the OpenGL type identifier that corresponds to short. | |
| static GLenum | GetGLType (GLint const *) |
| Returns the OpenGL type identifier that corresponds to int. | |
| static GLenum | GetGLType (GLuint const *) |
| Returns the OpenGL type identifier that corresponds to unsigned int. | |
| static Type | GetType (GLubyte const *) |
| Returns the Type that corresponds to unsigned byte. | |
| static Type | GetType (GLushort const *) |
| Returns the Type that corresponds to unsigned short. | |
| static Type | GetType (GLfloat const *) |
| Returns the Type that corresponds to float. | |
| static Type | GetType (GLbyte const *) |
| Returns the Type that corresponds to byte. | |
| static Type | GetType (GLshort const *) |
| Returns the Type that corresponds to short. | |
| static Type | GetType (GLint const *) |
| Returns the Type that corresponds to int. | |
| static Type | GetType (GLuint const *) |
| Returns the Type that corresponds to unsigned int. | |
| static GLenum | TextureFormat (Type type, int numChannels) |
| Returns the internal OpenGL texture type identifier for the given Type and the number of channels. | |
| static GLenum | TextureDataFormat (Type type, int numChannels) |
| Returns the OpenGL texture data format identifier for the given Type and the number of channels. | |
| static void | PrintVersion (std::ostream *outStream=&std::cout) |
| Prints the OpenGL version to the given stream. | |
| static void | CheckError (char const *sourcefile, int line, char const *call=nullptr, std::ostream *outStream=&std::cout) |
| Checks all previously triggered OpenGL errors and prints them to the given output stream. | |
| static bool | CheckContext () |
| Checks if an OpenGL context exists. Returns false if a valid OpenGL context cannot be retrieved. This is mostly useful for safely deleting previously allocated OpenGL objects. | |
