 Add a render pass to the render target. More...
 
virtual math::Color BackgroundColor () const =0
 Get the background color of the render target. This should be the same as the scene background color. More...
 
virtual void Copy (Image &_image) const =0
 Write rendered image to given Image. The RenderTarget will convert the underlying image to the specified format listed in the given Image. However if the given image is not of the correct size no work will be done. Calling this function before an image has been rendered will result in undefined behavior. More...

 Get render target height in pixels. More...

 Remove a render pass from the render target. More...

 Get a render pass by index. More...

 Destroy any resources associated with this object. Invoking any other functions after destroying an object will result in undefined behavior. More...
 
virtual unsigned int Id () const =0
 Get the object ID. This ID will be unique across all objects inside a given scene, but necessarily true for objects across different scenes. More...
 
virtual std::string Name () const =0
 Get the object name. This name will be unique across all objects inside a given scene, but necessarily true for objects across different scenes. More...
 
virtual void PostRender ()=0
 Post process this object and any of its children after rendering. More...
 
virtual void PreRender ()=0
 Prepare this object and any of its children for rendering. This should be called for each object in a scene just before rendering, which can be achieved by a single call to Scene::PreRender. More...

 Get the Scene that created this object. More...
