Public Member Functions | |
virtual void | draw (const GeometryBuffer &buffer)=0 |
Draw geometry from the given GeometryBuffer onto the surface that this RenderTarget represents. | |
virtual void | draw (const RenderQueue &queue)=0 |
Draw geometry from the given RenderQueue onto the surface that this RenderTarget represents. | |
virtual void | setArea (const Rectf &area)=0 |
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). | |
virtual const Rectf & | getArea () const =0 |
Return the area defined for this RenderTarget. | |
virtual bool | isImageryCache () const =0 |
Return whether the RenderTarget is an implementation that caches actual rendered imagery. | |
virtual void | activate ()=0 |
Activate the render target and put it in a state ready to be drawn to. | |
virtual void | deactivate ()=0 |
Deactivate the render target after having completed rendering. | |
virtual void | unprojectPoint (const GeometryBuffer &buff, const Vector2f &p_in, Vector2f &p_out) const =0 |
Take point p_in unproject it and put the result in p_out. Resulting point is local to GeometryBuffer buff. | |

Defines interface to some surface that can be rendered to. Concrete instances of objects that implement the RenderTarget interface are normally created via the Renderer object.
virtual void CEGUI::RenderTarget::activate | ( | ) | [pure virtual] |
Activate the render target and put it in a state ready to be drawn to.
Implemented in CEGUI::Direct3D9TextureTarget, CEGUI::OpenGLWGLPBTextureTarget, CEGUI::Direct3D10TextureTarget, CEGUI::Direct3D11TextureTarget, CEGUI::IrrlichtTextureTarget, CEGUI::OpenGL3FBOTextureTarget, CEGUI::OpenGLESFBOTextureTarget, CEGUI::DirectFBRenderTarget, CEGUI::OpenGLFBOTextureTarget, CEGUI::OpenGLGLXPBTextureTarget, and CEGUI::OpenGLApplePBTextureTarget.
virtual void CEGUI::RenderTarget::deactivate | ( | ) | [pure virtual] |
Deactivate the render target after having completed rendering.
Implemented in CEGUI::Direct3D9TextureTarget, CEGUI::OpenGLWGLPBTextureTarget, CEGUI::Direct3D10TextureTarget, CEGUI::Direct3D11TextureTarget, CEGUI::IrrlichtTextureTarget, CEGUI::OpenGL3FBOTextureTarget, CEGUI::OpenGLESFBOTextureTarget, CEGUI::DirectFBRenderTarget, CEGUI::OpenGLFBOTextureTarget, CEGUI::OpenGLGLXPBTextureTarget, and CEGUI::OpenGLApplePBTextureTarget.
virtual void CEGUI::RenderTarget::draw | ( | const GeometryBuffer & | buffer | ) | [pure virtual] |
Draw geometry from the given GeometryBuffer onto the surface that this RenderTarget represents.
buffer | GeometryBuffer object holding the geometry that should be drawn to the RenderTarget. |
Implemented in CEGUI::DirectFBRenderTarget.
virtual void CEGUI::RenderTarget::draw | ( | const RenderQueue & | queue | ) | [pure virtual] |
Draw geometry from the given RenderQueue onto the surface that this RenderTarget represents.
queue | RenderQueue object holding the geometry that should be drawn to the RenderTarget. |
Implemented in CEGUI::DirectFBRenderTarget.
virtual const Rectf& CEGUI::RenderTarget::getArea | ( | ) | const [pure virtual] |
Return the area defined for this RenderTarget.
Implemented in CEGUI::DirectFBRenderTarget.
virtual bool CEGUI::RenderTarget::isImageryCache | ( | ) | const [pure 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.
Implemented in CEGUI::Direct3D9ViewportTarget, CEGUI::OpenGLViewportTarget, CEGUI::OpenGLESViewportTarget, CEGUI::Direct3D9TextureTarget, CEGUI::Direct3D10TextureTarget, CEGUI::Direct3D11TextureTarget, CEGUI::IrrlichtTextureTarget, CEGUI::Direct3D10ViewportTarget, CEGUI::OgreWindowTarget, CEGUI::Direct3D11ViewportTarget, CEGUI::OpenGLESFBOTextureTarget, CEGUI::OpenGLTextureTarget, CEGUI::DirectFBRenderTarget, CEGUI::NullTextureTarget, CEGUI::OgreTextureTarget, and CEGUI::IrrlichtWindowTarget.
virtual void CEGUI::RenderTarget::setArea | ( | const Rectf & | area | ) | [pure 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).
area | Rect object describing the new area to be assigned to the RenderTarget. |
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. |
Implemented in CEGUI::DirectFBRenderTarget.
const String CEGUI::RenderTarget::EventAreaChanged [static] |
Event to be fired when the RenderTarget object's area has changed. Handlers are passed a const RenderTargetEventArgs reference with RenderTargetEventArgs::target set to the RenderTarget whose area changed.
