Function documentation

TGLFBO()

 Constructor.

~TGLFBO()

 Destructor.

void Init(int w, int h, int ms_samples = 0)

 Acquire GL resources for given width, height and number of
 multi-sampling samples.

void Release()

 Release the allocated GL resources.

void Bind()

 Bind the frame-buffer object.

void Unbind()

 Unbind the frame-buffer object.

void BindTexture()

 Bind texture.

void UnbindTexture()

 Unbind texture.

void SetAsReadBuffer()

void InitStandard()

void InitMultiSample()

UInt_t CreateAndAttachRenderBuffer(Int_t format, Int_t type)

UInt_t CreateAndAttachColorTexture()

 Initialize color-texture and attach it to current FB.

Bool_t GetRescaleToPow2()

 Return state of fgRescaleToPow2 static member.

void SetRescaleToPow2(Bool_t r)

 Set state of fgRescaleToPow2 static member.
 Default is kTRUE as this works better on older hardware, especially ATI.

TGLFBO(const TGLFBO& )

TGLFBO& operator=(const TGLFBO& )

Int_t GetW() const

{ return fW; }

Int_t GetH() const

{ return fReqW; }

Int_t GetReqH() const

{ return fReqH; }

Int_t GetMSSamples() const

{ return fMSSamples; }

Int_t GetMSCoverageSamples() const

{ return fMSCoverageSamples; }

Float_t GetWScale() const

{ return fWScale; }

{ return fHScale; }

Bool_t GetIsRescaled() const

{ return fIsRescaled; }
