virtual

Return 1 if this class is the same type of (or a subclass of) the named class.

Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkObjectBase.

◆ PrintSelf()

void vtkRenderbuffer::PrintSelf	(	ostream &	os,

	)

overridevirtual

Methods invoked by print to print information about the object including superclasses.

Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkObject.

◆ IsSupported()

static bool vtkRenderbuffer::IsSupported ( vtkRenderWindow * renWin )

static

Returns if the context supports the required extensions.

Extension will be loaded when the context is set.

◆ GetHandle()

virtual unsigned int vtkRenderbuffer::GetHandle ( )

virtual

Get the name of the buffer for use opengl code.

◆ SetContext()

void vtkRenderbuffer::SetContext ( vtkRenderWindow * win )

Setting the context has the side affect of initializing OpenGL required extensions and allocates an OpenGL name(handle) that is released when the object is destroyed.

NOTE: the reference count to the passed in object is not incremented. Contex must be set prior to other use.

◆ GetContext()

vtkRenderWindow * vtkRenderbuffer::GetContext ( )

Setting the context has the side affect of initializing OpenGL required extensions and allocates an OpenGL name(handle) that is released when the object is destroyed.

NOTE: the reference count to the passed in object is not incremented. Contex must be set prior to other use.

◆ CreateColorAttachment()

int vtkRenderbuffer::CreateColorAttachment	(	unsigned int	width,
		unsigned int	height
	)

Sets up an RGBAF renderbufffer for use as a color attachment.

Use mode to control READ or DRAW operation.

◆ CreateDepthAttachment()

int vtkRenderbuffer::CreateDepthAttachment	(	unsigned int	width,
		unsigned int	height
	)

Sets up an DEPTH renderbufffer for use as a color attachment.

Use mode to control READ or DRAW operation.

◆ Create() [1/2]

int vtkRenderbuffer::Create	(	unsigned int	format,
		unsigned int	width,
		unsigned int	height
	)

Sets up an renderbufffer.

Use mode to control READ or DRAW operation and format to control the internal format. (see OpenGL doc for more info)

int vtkRenderbuffer::Create	(	unsigned int	format,
		unsigned int	width,
		unsigned int	height,
		unsigned int	samples
	)

virtual

Get the buffer dimensions.

These are the properties of the OpenGL renderbuffer this instance represents.

◆ GetSamples()
