Public Member Functions
	OpenGl_FrameBuffer (GLint theTextureFormat=GL_RGBA8)
virtual	~OpenGl_FrameBuffer ()
GLsizei	GetSizeX () const
	Texture width.
GLsizei	GetSizeY () const
	Texture height.
GLsizei	GetVPSizeX () const
	Viewport width.
GLsizei	GetVPSizeY () const
	Viewport height.
Standard_Boolean	IsValid () const
	Returns true if current object was initialized.
Standard_Boolean	Init (const Handle< OpenGl_Context > &theGlContext, GLsizei theViewportSizeX, GLsizei theViewportSizeY, GLboolean toForcePowerOfTwo=GL_FALSE)
	Notice! Obsolete hardware (GeForce FX etc) doesn't support rectangular textures! There are 3 possible results if you are trying to create non power-of-two FBO on these cards: 1) FBO creation will fail, current implementation will try to generate compatible FBO; 2) FBO rendering will be done in software mode (ForceWare 'hack'); 3) FBO rendering will be incorrect (some obsolete Catalyst drivers).
void	Release (const Handle< OpenGl_Context > &theGlContext)
	Release GL objects.
void	SetupViewport ()
	Setup viewport to render into FBO.
void	ChangeViewport (const GLsizei theVPSizeX, const GLsizei theVPSizeY)
	Override viewport settings.
void	BindBuffer (const Handle< OpenGl_Context > &theGlContext)
	Bind frame buffer (to render into the texture).
void	UnbindBuffer (const Handle< OpenGl_Context > &theGlContext)
	Unbind frame buffer.
void	BindTexture ()
	Bind the texture.
void	UnbindTexture ()
	Unbind the texture.
Static Public Attributes
static const GLuint	NO_TEXTURE = 0
	Helpful constants.
static const GLuint	NO_FRAMEBUFFER = 0
static const GLuint	NO_RENDERBUFFER = 0
