Member Function Documentation

canWeave() [1/3]

bool SR::GLWeaverBase::canWeave

(

)

Used to determine if software weaving is possible on this device.

Deprecated:

Returns

bool indicating whether weaving can be done. Returns true when software weaving can be performed by GLWeaver. When false is returned, you can output side-by-side manually or let GLWeaver handle this.

canWeave() [2/3]

bool SR::GLWeaverBase::canWeave	(	unsigned int	width,
		unsigned int	height
	)

Used to determine if software weaving is possible for certain size and visibility to the currently bound framebuffer.

Parameters

width	of the image to be rendered to the bound framebuffer
height	of the image to be rendered to the bound framebuffer

Exceptions

std::runtime_error

if the window handle (HWND) becomes invalid during the execution of canWeave

Returns

bool indicating whether weaving can be done. Returns true when software weaving can be performed by GLWeaver. When false is returned, you can output side-by-side manually or let GLWeaver handle this.

canWeave() [3/3]

bool SR::GLWeaverBase::canWeave	(	unsigned int	width,
		unsigned int	height,
		unsigned int	xOffset,
		unsigned int	yOffset
	)

Used to determine if software weaving is possible for certain size and visibility to the currently bound framebuffer.

Parameters

width	of the image to be rendered to the bound framebuffer
height	of the image to be rendered to the bound framebuffer
xOffset	of the image to be rendered to the bound framebuffer
yOffset	of the image to be rendered to the bound framebuffer

Exceptions

std::runtime_error

if the window handle (HWND) becomes invalid during the execution of canWeave

Returns

bool indicating whether weaving can be done. Returns true when software weaving can be performed by GLWeaver. When false is returned, you can output side-by-side manually or let GLWeaver handle this.

getFrameBuffer()

GLuint SR::GLWeaverBase::getFrameBuffer

(

)

Returns the buffer that will be used to create a weaved imaged. This buffer expects a side-by-side image.

Returns

GLuint identifying a buffer generated with glGenFramebuffers

The buffer identifier can be bound using glBindFramebuffer to start rendering to it. Rendering to the buffer is identical to normal rendering and often starts with calling glClear.

setInputFrameBuffer()

void SR::GLWeaverBase::setInputFrameBuffer	(	GLuint	frameBufferID,
		GLuint	renderedTextureID
	)

Sets the buffer that will be used to create a weaved image.

Parameters

frameBufferID	ID of the frame buffer object used to render to the weaver input
renderedTextureID	ID of the texture used as a buffer for the weaver input. This texture needs to be attached as a color attachment of the frame buffer object!

setWindowHandle()

void SR::GLWeaverBase::setWindowHandle

(

HWND

handle

)

Sets the window handle of the application window. If the weaver was created using a deprecated constructor, setting window handle has no effect.

Parameters

window

Handle of the application window

weave() [1/2]

void SR::GLWeaverBase::weave	(	unsigned int	width,
		unsigned int	height
	)

Can be called to render a weaved image of a certain size to the currently bound framebuffer.

Parameters

width	of the image to be rendered to the bound framebuffer
height	of the image to be rendered to the bound framebuffer Should often be preceeded by glBindFramebuffer(GL_FRAMEBUFFER, 0) to start rendering to the default framebuffer again. The relative position of the user to the display in full-screen mode is equal to the direct output of the SR::EyeTracker class.

weave() [2/2]

void SR::GLWeaverBase::weave	(	unsigned int	width,
		unsigned int	height,
		unsigned int	xOffset,
		unsigned int	yOffset
	)

Can be called to render a weaved image of a certain size to the currently bound framebuffer.

Parameters

width	of the image to be rendered to the bound framebuffer
height	of the image to be rendered to the bound framebuffer
xOffset	of the image to be rendered to the bound framebuffer
yOffset	of the image to be rendered to the bound framebuffer Should often be preceeded by glBindFramebuffer(GL_FRAMEBUFFER, 0) to start rendering to the default framebuffer again. The relative position of the user to the display in full-screen mode is equal to the direct output of the SR::EyeTracker class.

Suppressing warning because if we don't want to export everything then solving the underlying problem requires modification of the API Warning Description: 'type' : class 'type1' needs to have dll-interface to be used by clients of class 'type2' Candidate for deprecation
