void CEGUI::Direct3D11RenderTarget::activate

(

)

[virtual]

Activate the render target and put it in a state ready to be drawn to.

Note:

You MUST call this before doing any rendering - if you do not call this, in the unlikely event that your application actually works, it will likely stop working in some future version.

Implements CEGUI::RenderTarget.

Reimplemented in CEGUI::Direct3D11TextureTarget.

void CEGUI::Direct3D11RenderTarget::deactivate

(

)

[virtual]

Deactivate the render target after having completed rendering.

Note:

You MUST call this after you finish rendering to the target - if you do not call this, in the unlikely event that your application actually works, it will likely stop working in some future version.

Implements CEGUI::RenderTarget.

Reimplemented in CEGUI::Direct3D11TextureTarget.

void CEGUI::Direct3D11RenderTarget::draw

(

const GeometryBuffer &

buffer

)

[virtual]

Draw geometry from the given GeometryBuffer onto the surface that this RenderTarget represents.

Parameters:

buffer

GeometryBuffer object holding the geometry that should be drawn to the RenderTarget.

Implements CEGUI::RenderTarget.

void CEGUI::Direct3D11RenderTarget::draw

(

const RenderQueue &

queue

)

[virtual]

Draw geometry from the given RenderQueue onto the surface that this RenderTarget represents.

Parameters:

queue

RenderQueue object holding the geometry that should be drawn to the RenderTarget.

Implements CEGUI::RenderTarget.

const Rect& CEGUI::Direct3D11RenderTarget::getArea

(

)

const [virtual]

Return the area defined for this RenderTarget.

Returns:

Rect object describing the currently defined area for this RenderTarget.

Implements CEGUI::RenderTarget.

void CEGUI::Direct3D11RenderTarget::setArea

(

const Rect &

area

)

[virtual]

Set the area for this RenderTarget. The exact action this function will take depends upon what the concrete class is representing. For example, with a 'view port' style RenderTarget, this should set the area that the view port occupies on the display (or rendering window).

Parameters:

area	Rect object describing the new area to be assigned to the RenderTarget.

Exceptions:

InvalidRequestException

May be thrown if the RenderTarget does not support setting or changing its area, or if the area change can not be satisfied for some reason.
