Public Member Functions

 Direct3D9ViewportTarget (Direct3D9Renderer &owner)
 Construct a default Direct3D9ViewportTarget that uses the current Direct3D9 viewport as it's initial area.
 
 Direct3D9ViewportTarget (Direct3D9Renderer &owner, const Rect &area)
 Construct a Direct3D9ViewportTarget that uses the specified Rect as it's initial area. More...
 
bool isImageryCache () const
 Return whether the RenderTarget is an implementation that caches actual rendered imagery. More...

 Constructor.
 
void draw (const GeometryBuffer &buffer)
 Draw geometry from the given GeometryBuffer onto the surface that this RenderTarget represents. More...
 
void draw (const RenderQueue &queue)
 Draw geometry from the given RenderQueue onto the surface that this RenderTarget represents. More...
 
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...
 
const RectgetArea () const
 Return the area defined for this RenderTarget. More...
 
void activate ()
 Activate the render target and put it in a state ready to be drawn to. More...
 
void deactivate ()
 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
areaRect 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

Implements CEGUI::RenderTarget.
