Member Function Documentation

void FBORenderbufferAttachment::createRenderBuffer ( )

Creates a renderbuffer object calling glGenRenderbuffers().

The identifier returned by glGenRenderbuffers() can be queried calling the handle() method.

void FBORenderbufferAttachment::deleteRenderBuffer ( )

Deletes the renderbuffer object created with the createRenderBuffer() method.

void vl::FBORenderbufferAttachment::setHandle ( GLuint handle ) [inline]

Sets the handle for this attachment, the handle must have been created by glGenRenderbuffers().

Normally you don't need to call this. See also: createRenderBuffer(), handle().

Definition at line 113 of file FramebufferObject.hpp.

GLuint vl::FBORenderbufferAttachment::handle ( ) const [inline]

Returns the handle obtained by createRenderBuffer() using glGenRenderbuffers()

Definition at line 116 of file FramebufferObject.hpp.

Referenced by bindAttachment(), and initStorage().

void FBORenderbufferAttachment::initStorage	(	int	w,
		int	h,
		int	samples
	)

Initializes the storage of the renderbuffer with the given sample count and dimensions.

This method does nothing if the the width, height and sample count has not changed since last time it was called. Note that the renderbuffer storage type is defined by the setType() method of FBOColorBufferAttachment, FBODepthBufferAttachment, FBOStencilBufferAttachment, FBODepthStencilBufferAttachment. See also setSamples().
