Detailed Description

OpenGL utility class.

Member Function Documentation

static void uicore::OpenGL::check_error ( )

static

Throw an exception if an OpenGL error was detected ( Using glGetError() )

Remember to call glGetError() to clear any previous errors

static std::vector<MessageLog_GL> uicore::OpenGL::get_message_log ( GLuint  numMsgs )

static

Get the OpenGL message log.

This is required for this function to operate OpenGLContextDescription gldesc; gldesc.set_debug(true); OpenGLTarget::set_description(gldesc);

static ProcAddress* uicore::OpenGL::get_proc_address ( const std::string &  function_name )

static

Get OpenGL extension specific function address.

static GLuint uicore::OpenGL::get_texture_handle ( const TexturePtr &  texture )

static

Returns the OpenGL texture handle.

static void uicore::OpenGL::set_active ( const GraphicContextPtr &  gc )

static

Sets the thread's OpenGL context to the one used by the graphic context.

static void uicore::OpenGL::set_active ( const OpenGLContextProvider *const  gc_provider )

static

Sets the thread's OpenGL context to the one used by the graphic context.

static bool uicore::OpenGL::set_active ( )

static

Sets the thread's OpenGL context to the first valid allocated one.

If a valid OpenGL context is not found, then "no render context" is set.

Returns

true = Success. false = No OpenGL contexts could be found

static TextureFormat_GL uicore::OpenGL::textureformat ( TextureFormat  format )

static

Returns the opengl texture format.

static GLenum uicore::OpenGL::to_cube_target ( int  index )

static

static GLenum uicore::OpenGL::to_enum ( DrawBuffer  buf )

static

static GLenum uicore::OpenGL::to_enum ( CompareFunction  func )

static

static GLenum uicore::OpenGL::to_enum ( StencilOp  op )

static

static GLenum uicore::OpenGL::to_enum ( CullMode  mode )

static

static GLenum uicore::OpenGL::to_enum ( FillMode  mode )

static

static GLenum uicore::OpenGL::to_enum ( BlendFunc  func )

static

static GLenum uicore::OpenGL::to_enum ( BlendEquation  eq )

static

static GLenum uicore::OpenGL::to_enum ( VertexAttributeDataType  value )

static

static GLenum uicore::OpenGL::to_enum ( PrimitivesType  value )

static

static GLenum uicore::OpenGL::to_enum ( LogicOp  op )

static

static GLenum uicore::OpenGL::to_enum ( TextureFilter  filter )

static

static

static GLenum uicore::OpenGL::to_enum ( TextureCompareMode  mode )

static

static GLenum uicore::OpenGL::to_enum ( BufferUsage  usage )

static

static GLenum uicore::OpenGL::to_enum ( BufferAccess  access )

static
