void	setArea (const Rect &area)
	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). More...

	Deactivate the render target after having completed rendering. More...
void	unprojectPoint (const GeometryBuffer &buff, const Vector2 &p_in, Vector2 &p_out) const
	Take point p_in unproject it and put the result in p_out. Resulting point is local to GeometryBuffer buff.

Detailed Description

Direct3D9 RenderTarget that represents a screen viewport.

Constructor & Destructor Documentation

CEGUI::Direct3D9ViewportTarget::Direct3D9ViewportTarget	(	Direct3D9Renderer &	owner,
		const Rect &	area
	)

Construct a Direct3D9ViewportTarget that uses the specified Rect as it's initial area.

Parameters

area	Rect object describing the initial viewport area that should be used for the RenderTarget.

Member Function Documentation

bool CEGUI::Direct3D9ViewportTarget::isImageryCache ( ) const

virtual

Return whether the RenderTarget is an implementation that caches actual rendered imagery.

Typically it is expected that texture based RenderTargets would return
true in response to this call.  Other types of RenderTarget, like
view port based targets, will more likely return false.

Returns

• true if the RenderTarget does cache rendered imagery.
• false if the RenderTarget does not cache rendered imagery.

Implements CEGUI::RenderTarget.
