Member Function Documentation

virtual const char* vl::FBORenderbufferAttachment::className ( ) [inline, virtual]

Returns the name of the class.

Reimplemented from vl::FBOAbstractAttachment.

Reimplemented in vl::FBOColorBufferAttachment, vl::FBODepthBufferAttachment, vl::FBOStencilBufferAttachment, and vl::FBODepthStencilBufferAttachment.

Definition at line 92 of file FramebufferObject.hpp.

void FBORenderbufferAttachment::create ( )

Creates a renderbuffer object calling glGenRenderbuffers().

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

Definition at line 498 of file FramebufferObject.cpp.

References GLEW_Has_Framebuffer_Object, mHandle, mReallocateRenderbuffer, VL_CHECK, VL_CHECK_OGL, and vl::VL_glGenRenderbuffers().

Referenced by bindAttachment().

void FBORenderbufferAttachment::destroy ( ) [virtual]

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

Reimplemented from vl::FBOAbstractAttachment.

Definition at line 512 of file FramebufferObject.cpp.

References GLEW_Has_Framebuffer_Object, mHandle, mHeight, mReallocateRenderbuffer, mWidth, VL_CHECK, VL_CHECK_OGL, and vl::VL_glDeleteRenderbuffers().

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: create(), handle().

Definition at line 110 of file FramebufferObject.hpp.

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

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

Definition at line 113 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().

Definition at line 529 of file FramebufferObject.cpp.

References vl::Log::error(), GLEW_Has_Framebuffer_Object, GLEW_Has_Framebuffer_Object_Multisample, handle(), height(), internalType(), mHeight, mReallocateRenderbuffer, mSamples, mWidth, samples(), VL_CHECK, VL_CHECK_OGL, vl::VL_glBindRenderbuffer(), vl::VL_glRenderbufferStorage(), vl::VL_glRenderbufferStorageMultisample(), and width().

void vl::FBORenderbufferAttachment::initStorage ( ) [inline]

The same as calling initStorage( width(), height() )

Definition at line 125 of file FramebufferObject.hpp.

References initStorage().

Referenced by bindAttachment(), and initStorage().

int vl::FBORenderbufferAttachment::width ( ) const [inline]

Returns the with of the renderbuffer storage.

Note that if renderbufferStorageReady() returns false it means that the renderbuffer has not been allocated yet.

Definition at line 132 of file FramebufferObject.hpp.

Referenced by bindAttachment(), and initStorage().

int vl::FBORenderbufferAttachment::height ( ) const [inline]

Returns the height of the renderbuffer storage.

Note that if renderbufferStorageReady() returns false it means that the renderbuffer has not been allocated yet.

Definition at line 139 of file FramebufferObject.hpp.

Referenced by bindAttachment(), and initStorage().

int vl::FBORenderbufferAttachment::samples ( ) const [inline]

Returns the number of samples to be used when allocating the renderbuffer's storage.

Note that if renderbufferStorageReady() returns false it means that the renderbuffer has not been allocated yet.

Definition at line 146 of file FramebufferObject.hpp.

Referenced by bindAttachment(), and initStorage().

void vl::FBORenderbufferAttachment::setWidth ( int w ) [inline]

The width of the renderbuffer storage to be allocated.

If 'w' is set to 0 the renderbuffer storage allocation will use the dimensions of the next FBORenderTarget bound.

Definition at line 152 of file FramebufferObject.hpp.

void vl::FBORenderbufferAttachment::setHeight ( int h ) [inline]

The height of the renderbuffer storage to be allocated.

If 'h' is set to 0 the renderbuffer storage allocation will use the dimensions of the next FBORenderTarget bound.

Definition at line 158 of file FramebufferObject.hpp.

void vl::FBORenderbufferAttachment::setSamples ( int samples ) [inline]

Sets the number of samples to be specified when allocating the renderbuffer's storage.

Definition at line 163 of file FramebufferObject.hpp.

bool vl::FBORenderbufferAttachment::renderbufferStorageReady ( ) const [inline]

Returns false if the renderbuffer storage needs to be created or reallocated due to a change of the sample count, renderbuffer type or dimension.

Definition at line 166 of file FramebufferObject.hpp.

void FBORenderbufferAttachment::bindAttachment	(	FBORenderTarget *	fbo,
		EAttachmentPoint	attach_point
	)		`[protected, virtual]`

Implements vl::FBOAbstractAttachment.
