activate()

void inviwo::FrameBufferObject::activate

(

)

Activate this FBO and store the currently set FBO

attachColorTexture() [1/3]

GLenum inviwo::FrameBufferObject::attachColorTexture	(	Texture2D *	texture,
		int	attachmentNumber,
		bool	attachFromRear = false,
		int	forcedLocation = -1
	)

If forcedLocation is > -1, this will enforce to position the color attachment at the given location in the draw buffer list (as used for attrib location in shaders). Side effects: affects subsequent buffer locations of already attached color buffers

attachColorTexture() [2/3]

GLenum inviwo::FrameBufferObject::attachColorTexture	(	Texture2DArray *	texture,
		int	attachmentNumber,
		bool	attachFromRear = false,
		int	forcedLocation = -1
	)

If forcedLocation is > -1, this will enforce to position the color attachment at the given location in the draw buffer list (as used for attrib location in shaders). Side effects: affects subsequent buffer locations of already attached color buffers

attachColorTexture() [3/3]

GLenum inviwo::FrameBufferObject::attachColorTexture	(	Texture3D *	texture,
		int	attachmentNumber,
		bool	attachFromRear = false,
		int	forcedLocation = -1
	)

If forcedLocation is > -1, this will enforce to position the color attachment at the given location in the draw buffer list (as used for attrib location in shaders). Side effects: affects subsequent buffer locations of already attached color buffers

attachColorTextureLayer() [1/2]

GLenum inviwo::FrameBufferObject::attachColorTextureLayer	(	Texture2DArray *	texture,
		int	attachmentNumber,
		int	layer,
		bool	attachFromRear = false,
		int	forcedLocation = -1
	)

If forcedLocation is > -1, this will enforce to position the color attachment at the given location in the draw buffer list (as used for attrib location in shaders). Side effects: affects subsequent buffer locations of already attached color buffers

attachColorTextureLayer() [2/2]

GLenum inviwo::FrameBufferObject::attachColorTextureLayer	(	Texture3D *	texture,
		int	attachmentNumber,
		int	layer,
		bool	attachFromRear = false,
		int	forcedLocation = -1
	)

If forcedLocation is > -1, this will enforce to position the color attachment at the given location in the draw buffer list (as used for attrib location in shaders). Side effects: affects subsequent buffer locations of already attached color buffers

attachTexture() [1/3]

void inviwo::FrameBufferObject::attachTexture	(	Texture2D *	texture,
		GLenum	attachmentID
	)

For attaching a 2D Texture

attachTexture() [2/3]

void inviwo::FrameBufferObject::attachTexture	(	Texture2DArray *	texture,
		GLenum	attachmentID
	)

For attaching a 2D Array Texture

attachTexture() [3/3]

void inviwo::FrameBufferObject::attachTexture	(	Texture3D *	texture,
		GLenum	attachmentID
	)

For attaching a 3D Texture

attachTextureLayer() [1/2]

void inviwo::FrameBufferObject::attachTextureLayer	(	Texture2DArray *	texture,
		GLenum	attachmentID,
		int	layer,
		int	level = 0
	)

For attaching a layer of a 2D Array Texture

attachTextureLayer() [2/2]

void inviwo::FrameBufferObject::attachTextureLayer	(	Texture3D *	texture,
		GLenum	attachmentID,
		int	layer
	)

For attaching a layer of a 3D Texture

deactivate()

void inviwo::FrameBufferObject::deactivate

(

)

Unbind FBO and restore previous one

deactivateFBO()

void inviwo::FrameBufferObject::deactivateFBO ( )

static

Use this function to unbind the FBO, without restoring the previous after this call, no FBO is bound

getAttachmentLocation()

int inviwo::FrameBufferObject::getAttachmentLocation

(

GLenum

attachmentID

)

const

Returns the location of the given attachment withing the registered draw buffers (e.g. used for glBindAttribLocation() and glFragDataLocation())

getDrawBuffers()

const std::vector<GLenum>& inviwo::FrameBufferObject::getDrawBuffers ( ) const

inline

Returns a compactified list of all color attachments (as used in glDrawBuffers())

getDrawBuffersInUse()

const std::vector<bool>& inviwo::FrameBufferObject::getDrawBuffersInUse ( ) const

inline

Returns a boolean field indicating whether attachment i has an attached texture

performAttachColorTexture()

bool inviwo::FrameBufferObject::performAttachColorTexture ( GLenum &  outAttachNumber, int  attachmentNumber, bool  attachFromRear = false, int  forcedLocation = -1  )

protected

If forcedLocation is > -1, this will enforce to position the color attachment at the given location in the draw buffer list (as used for attrib location in shaders). Side effects: affects subsequent buffer locations of already attached color buffers. NOTE: if forcedLocation is larger than the number of attachments, it will not be considered
